-Overview
-========
-
-This repository was created as a private staring point for the vpp documentation
-project. It is expected that it will be used as a sandbox that can be used to
-evaluate and comment on the new fd.io document structure.
-
-Build and Load Instructions
-===========================
-I build and load the documents using a mac, but these instuctions should be portable
-to any platform. I used the Python virtual environment.
-
-For more information on how to use the Python virtual enviroment check out
-`Installing packages using pip and virtualenv`_.
-
-.. _`Installing packages using pip and virtualenv`: https://packaging.python.org/guides/installing-using-pip-and-virtualenv/
-
-1. Get the repository
-
-.. code-block:: console
-
- git clone https://github.com/fdioDocs/vpp-docs
- cd vpp-docs
-
-2. Install the virtual environment
-
-.. code-block:: console
-
- python -m pip install --user virtualenv
- python -m virtualenv env
- source env/bin/activate
- pip install -r etc/requirements.txt
-
-.. note::
-
- To exit from the virtual environment execute:
-
-.. code-block:: console
-
- deactivate
-
-3. Build the html files
-
-.. code-block:: console
-
- cd docs
- make html
-
-4. View the results.

+This presentation describes the Transport Layer Development Kit (TLDK),
+which is an FD.io project that provides a set of libraries to accelerate L4-L7 protocol
+processing for DPDK-based applications. The initial implementation supports UDP,
+with work on TCP in progress. The project scope also includes integration of
+TLDK libraries into Vector Packet Processing (VPP) graph nodes to provide a host stack.
+This presentation was held during the DPDK US Summit on August 10th, 2016.

+
+Although packet forwarding with VPP and DPDK can now scale to tens of millions
+of packets per second per core, lack of alternatives to kernel-based
+sockets means that containers and host applications cannot
+take full advantage of this speed. To fill this gap, VPP
+was recently added functionality specifically designed
+to allow containerized or host applications to communicate
+via shared-memory if co-located, or via a high-performance
+TCP stack inter-host.
+
+This presentation was held during the 2017 DPDK Summit
+ on September 26th, 2017.

+Performance Considerations for Packet Processing on Intel Architecture
+######################################################################
+
+Event
+-----
+
+FD.io VPP is a modular, fast, scalable and deterministic data plane for NFV network workloads. Some common uses cases for VPP are as a vSwitch, a L3 Router, a vTEP, a Load Balancer, sockets applications and so much more, out of the box - no hacking required! It is optimized to take advantage of Intel Architecture Core and Platform accelerations to accelerate dataplane packet processing. It is permissively licensed as Apache 2, with a welcoming community of active developers behind it. It is extensible and can be used as an excellent set of building blocks to accelerate your next development project.
+
+This presentation covers the following content:
+* Introduction to the architecture and design of VPP.
+* A walk through common VPP use cases, cloud and NFV integration.
+* Creating Network Nodes: accelerating VPP IPSEC with Intel Technologies.
+* Performance analysis on Intel Architecture.
+
+This presentation was held during the on May 10th, 2017.

+Bounded-index Extensible Hashing (bihash)
+=========================================
+
+Vpp uses bounded-index extensible hashing to solve a variety of
+exact-match (key, value) lookup problems. Benefits of the current
+implementation:
+
+* Very high record count scaling, tested to 100,000,000 records.
+* Lookup performance degrades gracefully as the number of records increases
+* No reader locking required
+* Template implementation, it's easy to support arbitrary (key,value) types
+
+Bounded-index extensible hashing has been widely used in databases for
+decades.
+
+Bihash uses a two-level data structure:
+
+```
+ +-----------------+
+ | bucket-0 |
+ | log2_size |
+ | backing store |
+ +-----------------+
+ | bucket-1 |
+ | log2_size | +--------------------------------+
+ | backing store | --------> | KVP_PER_PAGE * key-value-pairs |
+ +-----------------+ | page 0 |
+ ... +--------------------------------+
+ +-----------------+ | KVP_PER_PAGE * key-value-pairs |
+ | bucket-2**N-1 | | page 1 |
+ | log2_size | +--------------------------------+
+ | backing store | ---
+ +-----------------+ +--------------------------------+
+ | KVP_PER_PAGE * key-value-pairs |
+ | page 2**(log2(size)) - 1 |
+ +--------------------------------+
+```
+
+Discussion of the algorithm
+---------------------------
+
+This structure has a couple of major advantages. In practice, each
+bucket entry fits into a 64-bit integer. Coincidentally, vpp's target
+CPU architectures support 64-bit atomic operations. When modifying the
+contents of a specific bucket, we do the following:
+
+* Make a working copy of the bucket's backing storage
+* Atomically swap a pointer to the working copy into the bucket array
+* Change the original backing store data
+* Atomically swap back to the original
+
+So, no reader locking is required to search a bihash table.
+
+At lookup time, the implementation computes a key hash code. We use
+the least-significant N bits of the hash to select the bucket.
+
+With the bucket in hand, we learn log2 (nBackingPages) for the
+selected bucket. At this point, we use the next log2_size bits from
+the hash code to select the specific backing page in which the
+(key,value) page will be found.
+
+Net result: we search **one** backing page, not 2**log2_size
+pages. This is a key property of the algorithm.
+
+When sufficient collisions occur to fill the backing pages for a given
+bucket, we double the bucket size, rehash, and deal the bucket
+contents into a double-sized set of backing pages. In the future, we
+may represent the size as a linear combination of two powers-of-two,
+to increase space efficiency.
+
+To solve the "jackpot case" where a set of records collide under
+hashing in a bad way, the implementation will fall back to linear
+search across 2**log2_size backing pages on a per-bucket basis.
+
+To maintain *space* efficiency, we should configure the bucket array
+so that backing pages are effectively utilized. Lookup performance
+tends to change *very litte* if the bucket array is too small or too
+large.
+
+Bihash depends on selecting an effective hash function. If one were to
+use a truly broken hash function such as "return 1ULL." bihash would
+still work, but it would be equivalent to poorly-programmed linear
+search.
+
+We often use cpu intrinsic functions - think crc32 - to rapidly
+compute a hash code which has decent statistics.
+
+Bihash Cookbook
+---------------
+
+### Using current (key,value) template instance types
+
+It's quite easy to use one of the template instance types. As of this
+writing, .../src/vppinfra provides pre-built templates for 8, 16, 20,
+24, 40, and 48 byte keys, u8 * vector keys, and 8 byte values.
+
+See .../src/vppinfra/{bihash_<key-size>_8}.h
+
+To define the data types, #include a specific template instance, most
+often in a subsystem header file:
+
+```c
+ #include <vppinfra/bihash_8_8.h>
+```
+
+If you're building a standalone application, you'll need to define the
+various functions by #including the method implementation file in a C
+source file.
+
+The core vpp engine currently uses most if not all of the known bihash
+types, so you probably won't need to #include the method
+implementation file.
+
+
+```c
+ #include <vppinfra/bihash_template.c>
+```
+
+Add an instance of the selected bihash data structure to e.g. a
+"main_t" structure:
+
+```c
+ typedef struct
+ {
+ ...
+ BVT (clib_bihash) hash;
+ or
+ clib_bihash_8_8_t hash;
+ ...
+ } my_main_t;
+```
+
+The BV macro concatenate its argument with the value of the
+preprocessor symbol BIHASH_TYPE. The BVT macro concatenates its
+argument with the value of BIHASH_TYPE and the fixed-string "_t". So
+in the above example, BVT (clib_bihash) generates "clib_bihash_8_8_t".
+
+If you're sure you won't decide to change the template / type name
+later, it's perfectly OK to code "clib_bihash_8_8_t" and so forth.
+
+In fact, if you #include multiple template instances in a single
+source file, you **must** use fully-enumerated type names. The macros
+stand no chance of working.
+
+### Initializing a bihash table
+
+Call the init function as shown. As a rough guide, pick a number of
+buckets which is approximately
+number_of_expected_records/BIHASH_KVP_PER_PAGE from the relevant
+template instance header-file. See previous discussion.
+
+The amount of memory selected should easily contain all of the
+records, with a generous allowance for hash collisions. Bihash memory
+is allocated separately from the main heap, and won't cost anything
+except kernel PTE's until touched, so it's OK to be reasonably
+generous.
+
+For example:
+
+```c
+ my_main_t *mm = &my_main;
+ clib_bihash_8_8_t *h;
+
+ h = &mm->hash_table;
+
+ clib_bihash_init_8_8 (h, "test", (u32) number_of_buckets,
+ (uword) memory_size);
+```
+
+### Add or delete a key/value pair
+
+Use BV(clib_bihash_add_del), or the explicit type variant:
+
+```c
+ clib_bihash_kv_8_8_t kv;
+ clib_bihash_8_8_t * h;
+ my_main_t *mm = &my_main;
+ clib_bihash_8_8_t *h;
+
+ h = &mm->hash_table;
+ kv.key = key_to_add_or_delete;
+ kv.value = value_to_add_or_delete;
+
+ clib_bihash_add_del_8_8 (h, &kv, is_add /* 1=add, 0=delete */);
+```
+
+In the delete case, kv.value is irrelevant. To change the value associated
+with an existing (key,value) pair, simply re-add the [new] pair.
+
+### Simple search
+
+The simplest possible (key, value) search goes like so:
+
+```c
+ clib_bihash_kv_8_8_t search_kv, return_kv;
+ clib_bihash_8_8_t * h;
+ my_main_t *mm = &my_main;
+ clib_bihash_8_8_t *h;
+
+ h = &mm->hash_table;
+ search_kv.key = key_to_add_or_delete;
+
+ if (clib_bihash_search_8_8 (h, &search_kv, &return_kv) < 0)
+ key_not_found()
+ else
+ key_not_found();
+```
+
+Note that it's perfectly fine to collect the lookup result
+
+```c
+ if (clib_bihash_search_8_8 (h, &search_kv, &search_kv))
+ key_not_found();
+ etc.
+```
+
+### Bihash vector processing
+
+When processing a vector of packets which need a certain lookup
+performed, it's worth the trouble to compute the key hash, and
+prefetch the correct bucket ahead of time.
+
+Here's a sketch of one way to write the required code:
+
+Dual-loop:
+* 6 packets ahead, prefetch 2x vlib_buffer_t's and 2x packet data
+ required to form the record keys
+* 4 packets ahead, form 2x record keys and call BV(clib_bihash_hash)
+ or the explicit hash function to calculate the record hashes.
+ Call 2x BV(clib_bihash_prefetch_bucket) to prefetch the buckets
+* 2 packets ahead, call 2x BV(clib_bihash_prefetch_data) to prefetch
+ 2x (key,value) data pages.
+* In the processing section, call 2x BV(clib_bihash_search_inline_with_hash)
+ to perform the search
+
+Programmer's choice whether to stash the hash code somewhere in
+vnet_buffer(b) metadata, or to use local variables.
+
+Single-loop:
+* Use simple search as shown above.
+
+### Walking a bihash table
+
+A fairly common scenario to build "show" commands involves walking a
+bihash table. It's simple enough:
+
+```c
+ my_main_t *mm = &my_main;
+ clib_bihash_8_8_t *h;
+ void callback_fn (clib_bihash_kv_8_8_t *, void *);
+
+ h = &mm->hash_table;
+
+ BV(clib_bihash_foreach_key_value_pair) (h, callback_fn, (void *) arg);
+```
+To nobody's great surprise: clib_bihash_foreach_key_value_pair
+iterates across the entire table, calling callback_fn with active
+entries.
+
+### Creating a new template instance
+
+Creating a new template is easy. Use one of the existing templates as
+a model, and make the obvious changes. The hash and key_compare
+methods are performance-critical in multiple senses.
+
+If the key compare method is slow, every lookup will be slow. If the
+hash function is slow, same story. If the hash function has poor
+statistical properties, space efficiency will suffer. In the limit, a
+bad enough hash function will cause large portions of the table to
+revert to linear search.
+
+Use of the best available vector unit is well worth the trouble in the
+hash and key_compare functions.

+Feature Arcs
+============
+
+A significant number of vpp features are configurable on a per-interface
+or per-system basis. Rather than ask feature coders to manually
+construct the required graph arcs, we built a general mechanism to
+manage these mechanics.
+
+Specifically, feature arcs comprise ordered sets of graph nodes. Each
+feature node in an arc is independently controlled. Feature arc nodes
+are generally unaware of each other. Handing a packet to "the next
+feature node" is quite inexpensive.
+
+The feature arc implementation solves the problem of creating graph arcs
+used for steering.
+
+At the beginning of a feature arc, a bit of setup work is needed, but
+only if at least one feature is enabled on the arc.
+
+On a per-arc basis, individual feature definitions create a set of
+ordering dependencies. Feature infrastructure performs a topological
+sort of the ordering dependencies, to determine the actual feature
+order. Missing dependencies **will** lead to runtime disorder. See
+<https://gerrit.fd.io/r/#/c/12753> for an example.
+
+If no partial order exists, vpp will refuse to run. Circular dependency
+loops of the form "a then b, b then c, c then a" are impossible to
+satisfy.
+
+Adding a feature to an existing feature arc
+-------------------------------------------
+
+To nobody's great surprise, we set up feature arcs using the typical
+"macro -> constructor function -> list of declarations" pattern:
+
+```c
+ VNET_FEATURE_INIT (mactime, static) =
+ {
+ .arc_name = "device-input",
+ .node_name = "mactime",
+ .runs_before = VNET_FEATURES ("ethernet-input"),
+ };
+```
+
+This creates a "mactime" feature on the "device-input" arc.
+
+Once per frame, dig up the vnet\_feature\_config\_main\_t corresponding
+to the "device-input" feature arc:
+
+```c
+ vnet_main_t *vnm = vnet_get_main ();
+ vnet_interface_main_t *im = &vnm->interface_main;
+ u8 arc = im->output_feature_arc_index;
+ vnet_feature_config_main_t *fcm;
+
+ fcm = vnet_feature_get_config_main (arc);
+```
+
+Note that in this case, we've stored the required arc index - assigned
+by the feature infrastructure - in the vnet\_interface\_main\_t. Where
+to put the arc index is a programmer's decision when creating a feature
+arc.
+
+Per packet, set next0 to steer packets to the next node they should
+visit:
+
+```c
+ vnet_get_config_data (&fcm->config_main,
+ &b0->current_config_index /* value-result */,
+ &next0, 0 /* # bytes of config data */);
+```
+
+Configuration data is per-feature arc, and is often unused. Note that
+it's normal to reset next0 to divert packets elsewhere; often, to drop
+them for cause:
+
+```c
+ next0 = MACTIME_NEXT_DROP;
+ b0->error = node->errors[DROP_CAUSE];
+```
+
+Creating a feature arc
+----------------------
+
+Once again, we create feature arcs using constructor macros:
+
+```c
+ VNET_FEATURE_ARC_INIT (ip4_unicast, static) =
+ {
+ .arc_name = "ip4-unicast",
+ .start_nodes = VNET_FEATURES ("ip4-input", "ip4-input-no-checksum"),
+ .arc_index_ptr = &ip4_main.lookup_main.ucast_feature_arc_index,
+ };
+```
+
+In this case, we configure two arc start nodes to handle the
+"hardware-verified ip checksum or not" cases. During initialization,
+the feature infrastructure stores the arc index as shown.
+
+In the head-of-arc node, do the following to send packets along the
+feature arc:
+
+```c
+ ip_lookup_main_t *lm = &im->lookup_main;
+ arc = lm->ucast_feature_arc_index;
+```
+
+Once per packet, initialize packet metadata to walk the feature arc:
+
+```c
+vnet_feature_arc_start (arc, sw_if_index0, &next, b0);
+```
+
+Enabling / Disabling features
+-----------------------------
+
+Simply call vnet_feature_enable_disable to enable or disable a specific
+feature:
+
+```c
+ vnet_feature_enable_disable ("device-input", /* arc name */
+ "mactime", /* feature name */
+ sw_if_index, /* Interface sw_if_index */
+ enable_disable, /* 1 => enable */
+ 0 /* (void *) feature_configuration */,
+ 0 /* feature_configuration_nbytes */);
+```
+
+The feature_configuration opaque is seldom used.
+
+If you wish to make a feature a _de facto_ system-level concept, pass
+sw_if_index=0 at all times. Sw_if_index 0 is always valid, and
+corresponds to the "local" interface.
+
+Related "show" commands
+-----------------------
+
+To display the entire set of features, use "show features [verbose]". The
+verbose form displays arc indices, and feature indicies within the arcs
+
+```
+$ vppctl show features verbose
+Available feature paths
+<snip>
+[14] ip4-unicast:
+ [ 0]: nat64-out2in-handoff
+ [ 1]: nat64-out2in

+ [29]: ipsec-input-ip4
+ [30]: vpath-input-ip4
+ [31]: ip4-vxlan-bypass
+ [32]: ip4-lookup
+<snip>
+```
+
+Here, we learn that the ip4-unicast feature arc has index 14, and that
+e.g. ip4-inacl is the 25th feature in the generated partial order.
+
+To display the features currently active on a specific interface,
+use "show interface <name> features":
+
+```
+$ vppctl show interface GigabitEthernet3/0/0 features
+Feature paths configured on GigabitEthernet3/0/0...
+<snip>
+ip4-unicast:
+ nat44-out2in
+<snip>
+```
+
+Table of Feature Arcs
+---------------------
+
+Simply search for name-strings to track down the arc definition, location of
+the arc index, etc.
+
+```
+ | Arc Name |
+ |------------------|
+ | device-input |
+ | ethernet-output |
+ | interface-output |
+ | ip4-drop |

+VPPINFRA (Infrastructure)
+=========================
+
+The files associated with the VPP Infrastructure layer are located in
+the ./src/vppinfra folder.
+
+VPPinfra is a collection of basic c-library services, quite
+sufficient to build standalone programs to run directly on bare metal.
+It also provides high-performance dynamic arrays, hashes, bitmaps,
+high-precision real-time clock support, fine-grained event-logging, and
+data structure serialization.
+
+One fair comment / fair warning about vppinfra: you can\'t always tell a
+macro from an inline function from an ordinary function simply by name.
+Macros are used to avoid function calls in the typical case, and to
+cause (intentional) side-effects.
+
+Vppinfra has been around for almost 20 years and tends not to change
+frequently. The VPP Infrastructure layer contains the following
+functions:
+
+Vectors
+-------
+
+Vppinfra vectors are ubiquitous dynamically resized arrays with by user
+defined \"headers\". Many vpppinfra data structures (e.g. hash, heap,
+pool) are vectors with various different headers.
+
+The memory layout looks like this:
+
+```
+ User header (optional, uword aligned)
+ Alignment padding (if needed)
+ Vector length in elements
+ User's pointer -> Vector element 0
+ Vector element 1
+ ...
+ Vector element N-1
+```
+
+As shown above, the vector APIs deal with pointers to the 0th element of
+a vector. Null pointers are valid vectors of length zero.
+
+To avoid thrashing the memory allocator, one often resets the length of
+a vector to zero while retaining the memory allocation. Set the vector
+length field to zero via the vec\_reset\_length(v) macro. \[Use the
+macro! It's smart about NULL pointers.\]
+
+Typically, the user header is not present. User headers allow for other
+data structures to be built atop vppinfra vectors. Users may specify the
+alignment for data elements via the [vec]()\*\_aligned macros.
+
+Vectors elements can be any C type e.g. (int, double, struct bar). This
+is also true for data types built atop vectors (e.g. heap, pool, etc.).
+Many macros have \_a variants supporting alignment of vector data and
+\_h variants supporting non-zero-length vector headers. The \_ha
+variants support both.
+
+Inconsistent usage of header and/or alignment related macro variants
+will cause delayed, confusing failures.
+
+Standard programming error: memorize a pointer to the ith element of a
+vector, and then expand the vector. Vectors expand by 3/2, so such code
+may appear to work for a period of time. Correct code almost always
+memorizes vector **indices** which are invariant across reallocations.
+
+In typical application images, one supplies a set of global functions
+designed to be called from gdb. Here are a few examples:
+
+- vl(v) - prints vec\_len(v)
+- pe(p) - prints pool\_elts(p)
+- pifi(p, index) - prints pool\_is\_free\_index(p, index)
+- debug\_hex\_bytes (p, nbytes) - hex memory dump nbytes starting at p
+
+Use the "show gdb" debug CLI command to print the current set.
+
+Bitmaps
+-------
+
+Vppinfra bitmaps are dynamic, built using the vppinfra vector APIs.
+Quite handy for a variety jobs.
+
+Pools
+-----
+
+Vppinfra pools combine vectors and bitmaps to rapidly allocate and free
+fixed-size data structures with independent lifetimes. Pools are perfect
+for allocating per-session structures.
+
+Hashes
+------
+
+Vppinfra provides several hash flavors. Data plane problems involving
+packet classification / session lookup often use
+./src/vppinfra/bihash\_template.\[ch\] bounded-index extensible
+hashes. These templates are instantiated multiple times, to efficiently
+service different fixed-key sizes.
+
+Bihashes are thread-safe. Read-locking is not required. A simple
+spin-lock ensures that only one thread writes an entry at a time.
+
+The original vppinfra hash implementation in
+./src/vppinfra/hash.\[ch\] are simple to use, and are often used in
+control-plane code which needs exact-string-matching.
+
+In either case, one almost always looks up a key in a hash table to
+obtain an index in a related vector or pool. The APIs are simple enough,
+but one must take care when using the unmanaged arbitrary-sized key
+variant. Hash\_set\_mem (hash\_table, key\_pointer, value) memorizes
+key\_pointer. It is usually a bad mistake to pass the address of a
+vector element as the second argument to hash\_set\_mem. It is perfectly
+fine to memorize constant string addresses in the text segment.
+
+Format
+------
+
+Vppinfra format is roughly equivalent to printf.
+
+Format has a few properties worth mentioning. Format's first argument is
+a (u8 \*) vector to which it appends the result of the current format
+operation. Chaining calls is very easy:
+
+```c
+ u8 * result;
+
+ result = format (0, "junk = %d, ", junk);
+ result = format (result, "more junk = %d\n", more_junk);
+```
+
+As previously noted, NULL pointers are perfectly proper 0-length
+vectors. Format returns a (u8 \*) vector, **not** a C-string. If you
+wish to print a (u8 \*) vector, use the "%v" format string. If you need
+a (u8 \*) vector which is also a proper C-string, either of these
+schemes may be used:
+
+```c
+ vec_add1 (result, 0)
+ or
+ result = format (result, "<whatever>%c", 0);
+```
+
+Remember to vec\_free() the result if appropriate. Be careful not to
+pass format an uninitialized (u8 \*).
+
+Format implements a particularly handy user-format scheme via the "%U"
+format specification. For example:
+
+```c
+ u8 * format_junk (u8 * s, va_list *va)
+ {
+ junk = va_arg (va, u32);
+ s = format (s, "%s", junk);
+ return s;
+ }
+
+ result = format (0, "junk = %U, format_junk, "This is some junk");
+```
+
+format\_junk() can invoke other user-format functions if desired. The
+programmer shoulders responsibility for argument type-checking. It is
+typical for user format functions to blow up if the va\_arg(va,
+type) macros don't match the caller's idea of reality.
+
+Unformat
+--------
+
+Vppinfra unformat is vaguely related to scanf, but considerably more
+general.
+
+A typical use case involves initializing an unformat\_input\_t from
+either a C-string or a (u8 \*) vector, then parsing via unformat() as
+follows:
+
+```c
+ unformat_input_t input;
+
+ unformat_init_string (&input, "<some-C-string>");
+ /* or */
+ unformat_init_vector (&input, <u8-vector>);
+```
+
+Then loop parsing individual elements:
+
+```c
+ while (unformat_check_input (&input) != UNFORMAT_END_OF_INPUT)
+ {
+ if (unformat (&input, "value1 %d", &value1))
+ ;/* unformat sets value1 */
+ else if (unformat (&input, "value2 %d", &value2)
+ ;/* unformat sets value2 */
+ else
+ return clib_error_return (0, "unknown input '%U'",
+ format_unformat_error, input);
+ }
+```
+
+As with format, unformat implements a user-unformat function capability
+via a "%U" user unformat function scheme.
+
+Vppinfra errors and warnings
+----------------------------
+
+Many functions within the vpp dataplane have return-values of type
+clib\_error\_t \*. Clib\_error\_t's are arbitrary strings with a bit of
+metadata \[fatal, warning\] and are easy to announce. Returning a NULL
+clib\_error\_t \* indicates "A-OK, no error."
+
+Clib\_warning(format-args) is a handy way to add debugging
+output; clib warnings prepend function:line info to unambiguously locate
+the message source. Clib\_unix\_warning() adds perror()-style Linux
+system-call information. In production images, clib\_warnings result in
+syslog entries.
+
+Serialization
+-------------
+
+Vppinfra serialization support allows the programmer to easily serialize
+and unserialize complex data structures.
+
+The underlying primitive serialize/unserialize functions use network
+byte-order, so there are no structural issues serializing on a
+little-endian host and unserializing on a big-endian host.
+
+Event-logger, graphical event log viewer
+----------------------------------------
+
+The vppinfra event logger provides very lightweight (sub-100ns)
+precisely time-stamped event-logging services. See
+./src/vppinfra/{elog.c, elog.h}
+
+Serialization support makes it easy to save and ultimately to combine a
+set of event logs. In a distributed system running NTP over a local LAN,
+we find that event logs collected from multiple system elements can be
+combined with a temporal uncertainty no worse than 50us.
+
+A typical event definition and logging call looks like this:
+
+```c
+ ELOG_TYPE_DECLARE (e) =
+ {
+ .format = "tx-msg: stream %d local seq %d attempt %d",
+ .format_args = "i4i4i4",
+ };
+ struct { u32 stream_id, local_sequence, retry_count; } * ed;
+ ed = ELOG_DATA (m->elog_main, e);
+ ed->stream_id = stream_id;
+ ed->local_sequence = local_sequence;
+ ed->retry_count = retry_count;
+```
+
+The ELOG\_DATA macro returns a pointer to 20 bytes worth of arbitrary
+event data, to be formatted (offline, not at runtime) as described by
+format\_args. Aside from obvious integer formats, the CLIB event logger
+provides a couple of interesting additions. The "t4" format
+pretty-prints enumerated values:
+
+```c
+ ELOG_TYPE_DECLARE (e) =
+ {
+ .format = "get_or_create: %s",
+ .format_args = "t4",
+ .n_enum_strings = 2,
+ .enum_strings = { "old", "new", },
+ };
+```
+
+The "t" format specifier indicates that the corresponding datum is an
+index in the event's set of enumerated strings, as shown in the previous
+event type definition.
+
+The “T” format specifier indicates that the corresponding datum is an
+index in the event log’s string heap. This allows the programmer to emit
+arbitrary formatted strings. One often combines this facility with a
+hash table to keep the event-log string heap from growing arbitrarily
+large.
+
+Noting the 20-octet limit per-log-entry data field, the event log
+formatter supports arbitrary combinations of these data types. As in:
+the ".format" field may contain one or more instances of the following:
+
+- i1 - 8-bit unsigned integer
+- i2 - 16-bit unsigned integer
+- i4 - 32-bit unsigned integer
+- i8 - 64-bit unsigned integer
+- f4 - float
+- f8 - double
+- s - NULL-terminated string - be careful
+- sN - N-byte character array
+- t1,2,4 - per-event enumeration ID
+- T4 - Event-log string table offset
+
+The vpp engine event log is thread-safe, and is shared by all threads.
+Take care not to serialize the computation. Although the event-logger is
+about as fast as practicable, it's not appropriate for per-packet use in
+hard-core data plane code. It's most appropriate for capturing rare
+events - link up-down events, specific control-plane events and so
+forth.
+
+The vpp engine has several debug CLI commands for manipulating its event
+log:
+
+```
+ vpp# event-logger clear
+ vpp# event-logger save <filename> # for security, writes into /tmp/<filename>.
+ # <filename> must not contain '.' or '/' characters
+ vpp# show event-logger [all] [<nnn>] # display the event log
+ # by default, the last 250 entries
+```
+
+The event log defaults to 128K entries. The command-line argument "...
+vlib { elog-events nnn } ..." configures the size of the event log.
+
+As described above, the vpp engine event log is thread-safe and shared.
+To avoid confusing non-appearance of events logged by worker threads,
+make sure to code vlib\_global\_main.elog\_main - instead of
+vm->elog\_main. The latter form is correct in the main thread, but
+will almost certainly produce bad results in worker threads.
+
+G2 graphical event viewer
+-------------------------
+
+The g2 graphical event viewer can display serialized vppinfra event logs
+directly, or via the c2cpel tool.

+Plugins
+=======
+
+vlib implements a straightforward plug-in DLL mechanism. VLIB client
+applications specify a directory to search for plug-in .DLLs, and a name
+filter to apply (if desired). VLIB needs to load plug-ins very early.
+
+Once loaded, the plug-in DLL mechanism uses dlsym to find and verify a
+vlib\_plugin\_registration data structure in the newly-loaded plug-in.

+Software Architecture
+=====================
+
+The fd.io vpp implementation is a third-generation vector packet
+processing implementation specifically related to US Patent 7,961,636,
+as well as earlier work. Note that the Apache-2 license specifically
+grants non-exclusive patent licenses; we mention this patent as a point
+of historical interest.
+
+For performance, the vpp dataplane consists of a directed graph of
+forwarding nodes which process multiple packets per invocation. This
+schema enables a variety of micro-processor optimizations: pipelining
+and prefetching to cover dependent read latency, inherent I-cache phase
+behavior, vector instructions. Aside from hardware input and hardware
+output nodes, the entire forwarding graph is portable code.
+
+Depending on the scenario at hand, we often spin up multiple worker
+threads which process ingress-hashes packets from multiple queues using
+identical forwarding graph replicas.
+
+VPP Layers - Implementation Taxonomy
+------------------------------------
+
+
+
+- VPP Infra - the VPP infrastructure layer, which contains the core
+ library source code. This layer performs memory functions, works
+ with vectors and rings, performs key lookups in hash tables, and
+ works with timers for dispatching graph nodes.
+- VLIB - the vector processing library. The vlib layer also handles
+ various application management functions: buffer, memory and graph
+ node management, maintaining and exporting counters, thread
+ management, packet tracing. Vlib implements the debug CLI (command
+ line interface).
+- VNET - works with VPP\'s networking interface (layers 2, 3, and 4)
+ performs session and traffic management, and works with devices and
+ the data control plane.
+- Plugins - Contains an increasingly rich set of data-plane plugins,
+ as noted in the above diagram.
+- VPP - the container application linked against all of the above.
+
+It's important to understand each of these layers in a certain amount of
+detail. Much of the implementation is best dealt with at the API level
+and otherwise left alone.

+
+VLIB (Vector Processing Library)
+================================
+
+The files associated with vlib are located in the ./src/{vlib,
+vlibapi, vlibmemory} folders. These libraries provide vector
+processing support including graph-node scheduling, reliable multicast
+support, ultra-lightweight cooperative multi-tasking threads, a CLI,
+plug in .DLL support, physical memory and Linux epoll support. Parts of
+this library embody US Patent 7,961,636.
+
+Init function discovery
+-----------------------
+
+vlib applications register for various \[initialization\] events by
+placing structures and \_\_attribute\_\_((constructor)) functions into
+the image. At appropriate times, the vlib framework walks
+constructor-generated singly-linked structure lists, calling the
+indicated functions. vlib applications create graph nodes, add CLI
+functions, start cooperative multi-tasking threads, etc. etc. using this
+mechanism.
+
+vlib applications invariably include a number of VLIB\_INIT\_FUNCTION
+(my\_init\_function) macros.
+
+Each init / configure / etc. function has the return type clib\_error\_t
+\*. Make sure that the function returns 0 if all is well, otherwise the
+framework will announce an error and exit.
+
+vlib applications must link against vppinfra, and often link against
+other libraries such as VNET. In the latter case, it may be necessary to
+explicitly reference symbol(s) otherwise large portions of the library
+may be AWOL at runtime.
+
+Node Graph Initialization
+-------------------------
+
+vlib packet-processing applications invariably define a set of graph
+nodes to process packets.
+
+One constructs a vlib\_node\_registration\_t, most often via the
+VLIB\_REGISTER\_NODE macro. At runtime, the framework processes the set
+of such registrations into a directed graph. It is easy enough to add
+nodes to the graph at runtime. The framework does not support removing
+nodes.
+
+vlib provides several types of vector-processing graph nodes, primarily
+to control framework dispatch behaviors. The type member of the
+vlib\_node\_registration\_t functions as follows:
+
+- VLIB\_NODE\_TYPE\_PRE\_INPUT - run before all other node types
+- VLIB\_NODE\_TYPE\_INPUT - run as often as possible, after pre\_input
+ nodes
+- VLIB\_NODE\_TYPE\_INTERNAL - only when explicitly made runnable by
+ adding pending frames for processing
+- VLIB\_NODE\_TYPE\_PROCESS - only when explicitly made runnable.
+ "Process" nodes are actually cooperative multi-tasking threads. They
+ **must** explicitly suspend after a reasonably short period of time.
+
+For a precise understanding of the graph node dispatcher, please read
+./src/vlib/main.c:vlib\_main\_loop.
+
+Graph node dispatcher
+---------------------
+
+Vlib\_main\_loop() dispatches graph nodes. The basic vector processing
+algorithm is diabolically simple, but may not be obvious from even a
+long stare at the code. Here's how it works: some input node, or set of
+input nodes, produce a vector of work to process. The graph node
+dispatcher pushes the work vector through the directed graph,
+subdividing it as needed, until the original work vector has been
+completely processed. At that point, the process recurs.
+
+This scheme yields a stable equilibrium in frame size, by construction.
+Here's why: as the frame size increases, the per-frame-element
+processing time decreases. There are several related forces at work; the
+simplest to describe is the effect of vector processing on the CPU L1
+I-cache. The first frame element \[packet\] processed by a given node
+warms up the node dispatch function in the L1 I-cache. All subsequent
+frame elements profit. As we increase the number of frame elements, the
+cost per element goes down.
+
+Under light load, it is a crazy waste of CPU cycles to run the graph
+node dispatcher flat-out. So, the graph node dispatcher arranges to wait
+for work by sitting in a timed epoll wait if the prevailing frame size
+is low. The scheme has a certain amount of hysteresis to avoid
+constantly toggling back and forth between interrupt and polling mode.
+Although the graph dispatcher supports interrupt and polling modes, our
+current default device drivers do not.
+
+The graph node scheduler uses a hierarchical timer wheel to reschedule
+process nodes upon timer expiration.
+
+Graph dispatcher internals
+--------------------------
+
+This section may be safely skipped. It's not necessary to understand
+graph dispatcher internals to create graph nodes.
+
+Vector Data Structure
+---------------------
+
+In vpp / vlib, we represent vectors as instances of the vlib_frame_t type:
+
+```c
+ typedef struct vlib_frame_t
+ {
+ /* Frame flags. */
+ u16 flags;
+
+ /* Number of scalar bytes in arguments. */
+ u8 scalar_size;
+
+ /* Number of bytes per vector argument. */
+ u8 vector_size;
+
+ /* Number of vector elements currently in frame. */
+ u16 n_vectors;
+
+ /* Scalar and vector arguments to next node. */
+ u8 arguments[0];
+ } vlib_frame_t;
+```
+
+Note that one _could_ construct all kinds of vectors - including
+vectors with some associated scalar data - using this structure. In
+the vpp application, vectors typically use a 4-byte vector element
+size, and zero bytes' worth of associated per-frame scalar data.
+
+Frames are always allocated on CLIB_CACHE_LINE_BYTES boundaries.
+Frames have u32 indices which make use of the alignment property, so
+the maximum feasible main heap offset of a frame is
+CLIB_CACHE_LINE_BYTES * 0xFFFFFFFF: 64*4 = 256 Gbytes.
+
+Scheduling Vectors
+------------------
+
+As you can see, vectors are not directly associated with graph
+nodes. We represent that association in a couple of ways. The
+simplest is the vlib\_pending\_frame\_t:
+
+```c
+ /* A frame pending dispatch by main loop. */
+ typedef struct
+ {
+ /* Node and runtime for this frame. */
+ u32 node_runtime_index;
+
+ /* Frame index (in the heap). */
+ u32 frame_index;
+
+ /* Start of next frames for this node. */
+ u32 next_frame_index;
+
+ /* Special value for next_frame_index when there is no next frame. */
+ #define VLIB_PENDING_FRAME_NO_NEXT_FRAME ((u32) ~0)
+ } vlib_pending_frame_t;
+```
+
+Here is the code in .../src/vlib/main.c:vlib_main_or_worker_loop()
+which processes frames:
+
+```c
+ /*
+ * Input nodes may have added work to the pending vector.
+ * Process pending vector until there is nothing left.
+ * All pending vectors will be processed from input -> output.
+ */
+ for (i = 0; i < _vec_len (nm->pending_frames); i++)
+ cpu_time_now = dispatch_pending_node (vm, i, cpu_time_now);
+ /* Reset pending vector for next iteration. */
+```
+
+The pending frame node_runtime_index associates the frame with the
+node which will process it.
+
+Complications
+-------------
+
+Fasten your seatbelt. Here's where the story - and the data structures
+\- become quite complicated...
+
+At 100,000 feet: vpp uses a directed graph, not a directed _acyclic_
+graph. It's really quite normal for a packet to visit ip\[46\]-lookup
+multiple times. The worst-case: a graph node which enqueues packets to
+itself.
+
+To deal with this issue, the graph dispatcher must force allocation of
+a new frame if the current graph node's dispatch function happens to
+enqueue a packet back to itself.
+
+There are no guarantees that a pending frame will be processed
+immediately, which means that more packets may be added to the
+underlying vlib_frame_t after it has been attached to a
+vlib_pending_frame_t. Care must be taken to allocate new
+frames and pending frames if a (pending\_frame, frame) pair fills.
+
+Next frames, next frame ownership
+---------------------------------
+
+The vlib\_next\_frame\_t is the last key graph dispatcher data structure:
+
+```c
+ typedef struct
+ {
+ /* Frame index. */
+ u32 frame_index;
+
+ /* Node runtime for this next. */
+ u32 node_runtime_index;
+
+ /* Next frame flags. */
+ u32 flags;
+
+ /* Reflects node frame-used flag for this next. */
+ #define VLIB_FRAME_NO_FREE_AFTER_DISPATCH \
+ VLIB_NODE_FLAG_FRAME_NO_FREE_AFTER_DISPATCH
+
+ /* This next frame owns enqueue to node
+ corresponding to node_runtime_index. */
+ #define VLIB_FRAME_OWNER (1 << 15)
+
+ /* Set when frame has been allocated for this next. */
+ #define VLIB_FRAME_IS_ALLOCATED VLIB_NODE_FLAG_IS_OUTPUT
+
+ /* Set when frame has been added to pending vector. */
+ #define VLIB_FRAME_PENDING VLIB_NODE_FLAG_IS_DROP
+
+ /* Set when frame is to be freed after dispatch. */
+ #define VLIB_FRAME_FREE_AFTER_DISPATCH VLIB_NODE_FLAG_IS_PUNT
+
+ /* Set when frame has traced packets. */
+ #define VLIB_FRAME_TRACE VLIB_NODE_FLAG_TRACE
+
+ /* Number of vectors enqueue to this next since last overflow. */
+ u32 vectors_since_last_overflow;
+ } vlib_next_frame_t;
+```
+
+Graph node dispatch functions call vlib\_get\_next\_frame (...) to
+set "(u32 \*)to_next" to the right place in the vlib_frame_t
+corresponding to the ith arc (aka next0) from the current node to the
+indicated next node.
+
+After some scuffling around - two levels of macros - processing
+reaches vlib\_get\_next\_frame_internal (...). Get-next-frame-internal
+digs up the vlib\_next\_frame\_t corresponding to the desired graph
+arc.
+
+The next frame data structure amounts to a graph-arc-centric frame
+cache. Once a node finishes adding element to a frame, it will acquire
+a vlib_pending_frame_t and end up on the graph dispatcher's
+run-queue. But there's no guarantee that more vector elements won't be
+added to the underlying frame from the same (source\_node,
+next\_index) arc or from a different (source\_node, next\_index) arc.
+
+Maintaining consistency of the arc-to-frame cache is necessary. The
+first step in maintaining consistency is to make sure that only one
+graph node at a time thinks it "owns" the target vlib\_frame\_t.
+
+Back to the graph node dispatch function. In the usual case, a certain
+number of packets will be added to the vlib\_frame\_t acquired by
+calling vlib\_get\_next\_frame (...).
+
+Before a dispatch function returns, it's required to call
+vlib\_put\_next\_frame (...) for all of the graph arcs it actually
+used. This action adds a vlib\_pending\_frame\_t to the graph
+dispatcher's pending frame vector.
+
+Vlib\_put\_next\_frame makes a note in the pending frame of the frame
+index, and also of the vlib\_next\_frame\_t index.
+
+dispatch\_pending\_node actions
+-------------------------------
+
+The main graph dispatch loop calls dispatch pending node as shown
+above.
+
+Dispatch\_pending\_node recovers the pending frame, and the graph node
+runtime / dispatch function. Further, it recovers the next\_frame
+currently associated with the vlib\_frame\_t, and detaches the
+vlib\_frame\_t from the next\_frame.
+
+In .../src/vlib/main.c:dispatch\_pending\_node(...), note this stanza:
+
+```c
+ /* Force allocation of new frame while current frame is being
+ dispatched. */
+ restore_frame_index = ~0;
+ if (nf->frame_index == p->frame_index)
+ {
+ nf->frame_index = ~0;
+ nf->flags &= ~VLIB_FRAME_IS_ALLOCATED;
+ if (!(n->flags & VLIB_NODE_FLAG_FRAME_NO_FREE_AFTER_DISPATCH))
+ restore_frame_index = p->frame_index;
+ }
+```
+
+dispatch\_pending\_node is worth a hard stare due to the several
+second-order optimizations it implements. Almost as an afterthought,
+it calls dispatch_node which actually calls the graph node dispatch
+function.
+
+Process / thread model
+----------------------
+
+vlib provides an ultra-lightweight cooperative multi-tasking thread
+model. The graph node scheduler invokes these processes in much the same
+way as traditional vector-processing run-to-completion graph nodes;
+plus-or-minus a setjmp/longjmp pair required to switch stacks. Simply
+set the vlib\_node\_registration\_t type field to
+vlib\_NODE\_TYPE\_PROCESS. Yes, process is a misnomer. These are
+cooperative multi-tasking threads.
+
+As of this writing, the default stack size is 2<<15 = 32kb.
+Initialize the node registration's process\_log2\_n\_stack\_bytes member
+as needed. The graph node dispatcher makes some effort to detect stack
+overrun, e.g. by mapping a no-access page below each thread stack.
+
+Process node dispatch functions are expected to be "while(1) { }" loops
+which suspend when not otherwise occupied, and which must not run for
+unreasonably long periods of time.
+
+"Unreasonably long" is an application-dependent concept. Over the years,
+we have constructed frame-size sensitive control-plane nodes which will
+use a much higher fraction of the available CPU bandwidth when the frame
+size is low. The classic example: modifying forwarding tables. So long
+as the table-builder leaves the forwarding tables in a valid state, one
+can suspend the table builder to avoid dropping packets as a result of
+control-plane activity.
+
+Process nodes can suspend for fixed amounts of time, or until another
+entity signals an event, or both. See the next section for a description
+of the vlib process event mechanism.
+
+When running in vlib process context, one must pay strict attention to
+loop invariant issues. If one walks a data structure and calls a
+function which may suspend, one had best know by construction that it
+cannot change. Often, it's best to simply make a snapshot copy of a data
+structure, walk the copy at leisure, then free the copy.
+
+Process events
+--------------
+
+The vlib process event mechanism API is extremely lightweight and easy
+to use. Here is a typical example:
+
+```c
+ vlib_main_t *vm = &vlib_global_main;
+ uword event_type, * event_data = 0;
+
+ while (1)
+ {
+ vlib_process_wait_for_event_or_clock (vm, 5.0 /* seconds */);
+
+ event_type = vlib_process_get_events (vm, &event_data);
+
+ switch (event_type) {
+ case EVENT1:
+ handle_event1s (event_data);
+ break;
+
+ case EVENT2:
+ handle_event2s (event_data);
+ break;
+
+ case ~0: /* 5-second idle/periodic */
+ handle_idle ();
+ break;
+
+ default: /* bug! */
+ ASSERT (0);
+ }
+
+ vec_reset_length(event_data);
+ }
+```
+
+In this example, the VLIB process node waits for an event to occur, or
+for 5 seconds to elapse. The code demuxes on the event type, calling
+the appropriate handler function. Each call to
+vlib\_process\_get\_events returns a vector of per-event-type data
+passed to successive vlib\_process\_signal\_event calls; it is a
+serious error to process only event\_data\[0\].
+
+Resetting the event\_data vector-length to 0 \[instead of calling
+vec\_free\] means that the event scheme doesn't burn cycles continuously
+allocating and freeing the event data vector. This is a common vppinfra
+/ vlib coding pattern, well worth using when appropriate.
+
+Signaling an event is easy, for example:
+
+```c
+ vlib_process_signal_event (vm, process_node_index, EVENT1,
+ (uword)arbitrary_event1_data); /* and so forth */
+```
+
+One can either know the process node index by construction - dig it out
+of the appropriate vlib\_node\_registration\_t - or by finding the
+vlib\_node\_t with vlib\_get\_node\_by\_name(...).
+
+Buffers
+-------
+
+vlib buffering solves the usual set of packet-processing problems,
+albeit at high performance. Key in terms of performance: one ordinarily
+allocates / frees N buffers at a time rather than one at a time. Except
+when operating directly on a specific buffer, one deals with buffers by
+index, not by pointer.
+
+Packet-processing frames are u32\[\] arrays, not
+vlib\_buffer\_t\[\] arrays.
+
+Packets comprise one or more vlib buffers, chained together as required.
+Multiple particle sizes are supported; hardware input nodes simply ask
+for the required size(s). Coalescing support is available. For obvious
+reasons one is discouraged from writing one's own wild and wacky buffer
+chain traversal code.
+
+vlib buffer headers are allocated immediately prior to the buffer data
+area. In typical packet processing this saves a dependent read wait:
+given a buffer's address, one can prefetch the buffer header
+\[metadata\] at the same time as the first cache line of buffer data.
+
+Buffer header metadata (vlib\_buffer\_t) includes the usual rewrite
+expansion space, a current\_data offset, RX and TX interface indices,
+packet trace information, and a opaque areas.
+
+The opaque data is intended to control packet processing in arbitrary
+subgraph-dependent ways. The programmer shoulders responsibility for
+data lifetime analysis, type-checking, etc.
+
+Buffers have reference-counts in support of e.g. multicast replication.
+
+Shared-memory message API
+-------------------------
+
+Local control-plane and application processes interact with the vpp
+dataplane via asynchronous message-passing in shared memory over
+unidirectional queues. The same application APIs are available via
+sockets.
+
+Capturing API traces and replaying them in a simulation environment
+requires a disciplined approach to the problem. This seems like a
+make-work task, but it is not. When something goes wrong in the
+control-plane after 300,000 or 3,000,000 operations, high-speed replay
+of the events leading up to the accident is a huge win.
+
+The shared-memory message API message allocator vl\_api\_msg\_alloc uses
+a particularly cute trick. Since messages are processed in order, we try
+to allocate message buffering from a set of fixed-size, preallocated
+rings. Each ring item has a "busy" bit. Freeing one of the preallocated
+message buffers merely requires the message consumer to clear the busy
+bit. No locking required.
+
+Debug CLI
+---------
+
+Adding debug CLI commands to VLIB applications is very simple.
+
+Here is a complete example:
+
+```c
+ static clib_error_t *
+ show_ip_tuple_match (vlib_main_t * vm,
+ unformat_input_t * input,
+ vlib_cli_command_t * cmd)
+ {
+ vlib_cli_output (vm, "%U\n", format_ip_tuple_match_tables, &routing_main);
+ return 0;
+ }
+
+ /* *INDENT-OFF* */
+ static VLIB_CLI_COMMAND (show_ip_tuple_command) =
+ {
+ .path = "show ip tuple match",
+ .short_help = "Show ip 5-tuple match-and-broadcast tables",
+ .function = show_ip_tuple_match,
+ };
+ /* *INDENT-ON* */
+```
+
+This example implements the "show ip tuple match" debug cli
+command. In ordinary usage, the vlib cli is available via the "vppctl"
+applicationn, which sends traffic to a named pipe. One can configure
+debug CLI telnet access on a configurable port.
+
+The cli implementation has an output redirection facility which makes it
+simple to deliver cli output via shared-memory API messaging,
+
+Particularly for debug or "show tech support" type commands, it would be
+wasteful to write vlib application code to pack binary data, write more
+code elsewhere to unpack the data and finally print the answer. If a
+certain cli command has the potential to hurt packet processing
+performance by running for too long, do the work incrementally in a
+process node. The client can wait.

+VNET (VPP Network Stack)
+========================
+
+The files associated with the VPP network stack layer are located in the
+./src/vnet folder. The Network Stack Layer is basically an
+instantiation of the code in the other layers. This layer has a vnet
+library that provides vectorized layer-2 and 3 networking graph nodes, a
+packet generator, and a packet tracer.
+
+In terms of building a packet processing application, vnet provides a
+platform-independent subgraph to which one connects a couple of
+device-driver nodes.
+
+Typical RX connections include "ethernet-input" \[full software
+classification, feeds ipv4-input, ipv6-input, arp-input etc.\] and
+"ipv4-input-no-checksum" \[if hardware can classify, perform ipv4 header
+checksum\].
+
+
+
+List of features and layer areas that VNET works with:
+
+Effective graph dispatch function coding
+----------------------------------------
+
+Over the 15 years, multiple coding styles have emerged: a
+single/dual/quad loop coding model (with variations) and a
+fully-pipelined coding model.
+
+Single/dual loops
+-----------------
+
+The single/dual/quad loop model variations conveniently solve problems
+where the number of items to process is not known in advance: typical
+hardware RX-ring processing. This coding style is also very effective
+when a given node will not need to cover a complex set of dependent
+reads.
+
+Here is an quad/single loop which can leverage up-to-avx512 SIMD vector
+units to convert buffer indices to buffer pointers:
+
+```c
+ static uword
+ simulated_ethernet_interface_tx (vlib_main_t * vm,
+ vlib_node_runtime_t *
+ node, vlib_frame_t * frame)
+ {
+ u32 n_left_from, *from;
+ u32 next_index = 0;
+ u32 n_bytes;
+ u32 thread_index = vm->thread_index;
+ vnet_main_t *vnm = vnet_get_main ();
+ vnet_interface_main_t *im = &vnm->interface_main;
+ vlib_buffer_t *bufs[VLIB_FRAME_SIZE], **b;
+ u16 nexts[VLIB_FRAME_SIZE], *next;
+
+ n_left_from = frame->n_vectors;
+ from = vlib_frame_args (frame);
+
+ /*
+ * Convert up to VLIB_FRAME_SIZE indices in "from" to
+ * buffer pointers in bufs[]
+ */
+ vlib_get_buffers (vm, from, bufs, n_left_from);
+ b = bufs;
+ next = nexts;
+
+ /*
+ * While we have at least 4 vector elements (pkts) to process..
+ */
+ while (n_left_from >= 4)
+ {
+ /* Prefetch next quad-loop iteration. */
+ if (PREDICT_TRUE (n_left_from >= 8))
+ {
+ vlib_prefetch_buffer_header (b[4], STORE);
+ vlib_prefetch_buffer_header (b[5], STORE);
+ vlib_prefetch_buffer_header (b[6], STORE);
+ vlib_prefetch_buffer_header (b[7], STORE);
+ }
+
+ /*
+ * $$$ Process 4x packets right here...
+ * set next[0..3] to send the packets where they need to go
+ */
+
+ do_something_to (b[0]);
+ do_something_to (b[1]);
+ do_something_to (b[2]);
+ do_something_to (b[3]);
+
+ /* Process the next 0..4 packets */
+ b += 4;
+ next += 4;
+ n_left_from -= 4;
+ }
+ /*
+ * Clean up 0...3 remaining packets at the end of the incoming frame
+ */
+ while (n_left_from > 0)
+ {
+ /*
+ * $$$ Process one packet right here...
+ * set next[0..3] to send the packets where they need to go
+ */
+ do_something_to (b[0]);
+
+ /* Process the next packet */
+ b += 1;
+ next += 1;
+ n_left_from -= 1;
+ }
+
+ /*
+ * Send the packets along their respective next-node graph arcs
+ * Considerable locality of reference is expected, most if not all
+ * packets in the inbound vector will traverse the same next-node
+ * arc
+ */
+ vlib_buffer_enqueue_to_next (vm, node, from, nexts, frame->n_vectors);
+
+ return frame->n_vectors;
+ }
+```
+
+Given a packet processing task to implement, it pays to scout around
+looking for similar tasks, and think about using the same coding
+pattern. It is not uncommon to recode a given graph node dispatch function
+several times during performance optimization.
+
+Packet tracer
+-------------
+
+Vlib includes a frame element \[packet\] trace facility, with a simple
+vlib cli interface. The cli is straightforward: "trace add
+input-node-name count".
+
+To trace 100 packets on a typical x86\_64 system running the dpdk
+plugin: "trace add dpdk-input 100". When using the packet generator:
+"trace add pg-input 100"
+
+Each graph node has the opportunity to capture its own trace data. It is
+almost always a good idea to do so. The trace capture APIs are simple.
+
+The packet capture APIs snapshoot binary data, to minimize processing at
+capture time. Each participating graph node initialization provides a
+vppinfra format-style user function to pretty-print data when required
+by the VLIB "show trace" command.
+
+Set the VLIB node registration ".format\_trace" member to the name of
+the per-graph node format function.
+
+Here's a simple example:
+
+```c
+ u8 * my_node_format_trace (u8 * s, va_list * args)
+ {
+ vlib_main_t * vm = va_arg (*args, vlib_main_t *);
+ vlib_node_t * node = va_arg (*args, vlib_node_t *);
+ my_node_trace_t * t = va_arg (*args, my_trace_t *);
+
+ s = format (s, "My trace data was: %d", t-><whatever>);
+
+ return s;
+ }
+```
+
+The trace framework hands the per-node format function the data it
+captured as the packet whizzed by. The format function pretty-prints the
+data as desired.

+Huge Pages
+----------
+
+VPP requires *'hugepages'* to run. VPP will overwrite existing hugepage
+settings when VPP is installed. By default, VPP sets the number of hugepages on
+a system to 1024 2M hugepages (1G hugepages are no longer supported). This is
+the number of hugepages on the system, not just used by VPP. When VPP is
+installed, the following file is copied to the system and used to apply the
+hugepage settings on VPP installation and system reboot:
+
+.. code-block:: console
+
+ $ cat /etc/sysctl.d/80-vpp.conf
+ # Number of 2MB hugepages desired
+ vm.nr_hugepages=1024
+
+ # Must be greater than or equal to (2 * vm.nr_hugepages).
+ vm.max_map_count=3096
+
+ # All groups allowed to access hugepages
+ vm.hugetlb_shm_group=0
+
+ # Shared Memory Max must be greator or equal to the total size of hugepages.
+ # For 2MB pages, TotalHugepageSize = vm.nr_hugepages * 2 * 1024 * 1024
+ # If the existing kernel.shmmax setting (cat /sys/proc/kernel/shmmax)
+ # is greater than the calculated TotalHugepageSize then set this parameter
+ # to current shmmax value.
+ kernel.shmmax=2147483648
+
+Depending on how the system is being used, this file can be updated to adjust
+the number of hugepages reserved on a system. Below are some examples of
+possible values.
+
+For a small VM with minimal workload:
+
+.. code-block:: console
+
+ vm.nr_hugepages=512
+ vm.max_map_count=2048
+ kernel.shmmax=1073741824
+
+For a large system running multiple VMs, each needing its own set of hugepages:
+
+.. code-block:: console
+
+ vm.nr_hugepages=32768
+ vm.max_map_count=66560
+ kernel.shmmax=68719476736
+
+
+.. note::
+
+ If VPP is being run in a Virtual Machine (VM), the VM must have hugepage
+ backing. When VPP is installed, it will attempt to overwrite existing
+ hugepage setting. If the VM does not have hugepage backing, this will fail,
+ but this may go unnoticed. When the VM is rebooted, on system startup,
+ *'vm.nr_hugepages'* will be reapplied, will fail, and the VM will abort kernel
+ boot, locking up the VM. To avoid this scenario, ensure the VM has enough
+ hugepage backing.

+=======================================
+VPP Configuration File - 'startup.conf'
+=======================================
+
+
+After a successful installation, VPP installs a startup config file named
+*'startup.conf'* in the *'/etc/vpp/'*' directory. This file can be tailored to
+make VPP run as desired, but contains default values for typical installations.
+Below are more details about this file and parameter and values it contains.
+
+Introduction
+------------
+
+The VPP network stack comes with several configuration options that can be
+provided either on the command line when VPP is started, or in a configuration
+file. Specific applications built on the stack have been known to require a dozen
+arguments, depending on requirements.
+
+Command-line Arguments
+----------------------
+
+Parameters are grouped by a section name. When providing more than one
+parameter to a section, all parameters for that section must be wrapped in
+curly braces. For example, to start VPP with configuration data via the
+command line with the section name *'unix'*:
+
+.. code-block:: console
+
+ $ sudo /usr/bin/vpp unix { interactive cli-listen 127.0.0.1:5002 }
+
+The command line can be presented as a single string or as several; anything
+given on the command line is concatenated with spaces into a single string
+before parsing. VPP applications must be able to locate their own executable
+images. The simplest way to ensure this will work is to invoke a VPP
+application by giving its absolute path. For example:
+*'/usr/bin/vpp <options>'* At startup, VPP applications parse through their
+own ELF-sections [primarily] to make lists of init, configuration, and exit
+handlers.
+
+When developing with VPP, in gdb it's often sufficient to start an application
+like this:
+
+.. code-block:: console
+
+ (gdb) run unix interactive
+
+Configuration File
+------------------
+
+It is also possible to supply the configuration parameters in a startup
+configuration. The path of the file is provided to the VPP application on its
+command line. The format of the configuration file is a simple text file with
+the same content as the command line, but with the benefit of being able to use
+newlines to make the content easier to read. For example:
+
+.. code-block:: console
+
+ $ cat /etc/vpp/startup.conf
+ unix {
+ nodaemon
+ log /var/log/vpp/vpp.log
+ full-coredump
+ cli-listen localhost:5002
+ }
+
+ api-trace {
+ on
+ }
+
+ dpdk {
+ dev 0000:03:00.0
+ }
+
+VPP is then instructed to load this file with the -c option. For example:
+
+.. code-block:: console
+
+ $ sudo /usr/bin/vpp -c /etc/vpp/startup.conf
+
+When the VPP service is started, VPP is started with this option via another
+installed file, vpp.service (Ubuntu: /lib/systemd/system/vpp.service and
+CentOS: /usr/lib/systemd/system/vpp.service). See *'ExecStart'* below:
+
+.. code-block:: console
+
+ $ cat /lib/systemd/system/vpp.service

+
+Configuration Parameters
+------------------------
+
+Below is the list of section names and their associated parameters. This is not
+an exhaustive list of parameters available. The command-line argument parsers
+can be found in the source code by searching for instances of the
+**VLIB_CONFIG_FUNCTION** and **VLIB_EARLY_CONFIG_FUNCTION** macro.
+
+For example, the invocation *'VLIB_CONFIG_FUNCTION (foo_config, "foo")'* will
+cause the function *'foo_config'* to receive all parameters given in a
+parameter block named "foo": "foo { arg1 arg2 arg3 ... }".

+"unix" Parameters
+_________________
+
+Configure VPP startup and behavior type attributes, as well and any OS based
+attributes.
+
+ * **interactive**
+ Attach CLI to stdin/out and provide a debugging command line interface.
+ Implies nodaemon.
+
+ **Example:** interactive
+
+ * **nodaemon**
+ Do not fork / background the vpp process. Typical when invoking VPP
+ applications from a process monitor. Set by default in the default
+ *'startup.conf'* file.
+
+ **Example:** nodaemon
+
+ * **log <filename>**
+ Logs the startup configuration and all subsequent CLI commands in filename.
+ Very useful in situations where folks don't remember or can't be bothered
+ to include CLI commands in bug reports. The default *'startup.conf'* file
+ is to write to *'/var/log/vpp/vpp.log'*.
+
+ In VPP 18.04, the default log file location was moved from '/tmp/vpp.log'
+ to '/var/log/vpp/vpp.log' . The VPP code is indifferent to the file location.
+ However, if SELinux is enabled, then the new location is required for the file
+ to be properly labeled. Check your local *'startup.conf'* file for the log file
+ location on your system.
+
+ **Example:** log /var/log/vpp/vpp-debug.log
+
+ * **exec|startup-config <filename>**
+ Read startup operational configuration from filename. The contents of the file
+ will be performed as though entered at the CLI. The two keywords are aliases
+ for the same function; if both are specified, only the last will have an effect.
+ The file contains CLI commands, for example:
+
+ | $ cat /usr/share/vpp/scripts/interface-up.txt
+ | set interface state TenGigabitEthernet1/0/0 up
+ | set interface state TenGigabitEthernet1/0/1 up
+
+ **Example:** startup-config /usr/share/vpp/scripts/interface-up.txt
+
+ * **gid number|name>**
+ Sets the effective group ID to the input group ID or group name of the calling
+ process.
+
+ **Example:** gid vpp
+
+ * **full-coredump**
+ Ask the Linux kernel to dump all memory-mapped address regions, instead of
+ just text+data+bss.
+
+ **Example:** full-coredump
+
+ * **coredump-size unlimited|<n>G|<n>M|<n>K|<n>**
+ Set the maximum size of the coredump file. The input value can be set in
+ GB, MB, KB or bytes, or set to *'unlimited'*.
+
+ **Example:** coredump-size unlimited
+
+ * **cli-listen <ipaddress:port>|<socket-path>**
+ Bind the CLI to listen at address localhost on TCP port 5002. This will
+ accept an ipaddress:port pair or a filesystem path; in the latter case a
+ local Unix socket is opened instead. The default *'startup.conf'* file
+ is to open the socket *'/run/vpp/cli.sock'*.
+
+ **Example:** cli-listen localhost:5002
+ **Example:** cli-listen /run/vpp/cli.sock
+
+ * **cli-line-mode**
+ Disable character-by-character I/O on stdin. Useful when combined with,
+ for example, emacs M-x gud-gdb.
+
+ **Example:** cli-line-mode
+
+ * **cli-prompt <string>**
+ Configure the CLI prompt to be string.
+
+ **Example:** cli-prompt vpp-2
+
+ * **cli-history-limit <n>**
+ Limit commmand history to <n> lines. A value of 0 disables command history.
+ Default value: 50
+
+ **Example:** cli-history-limit 100
+
+ * **cli-no-banner**
+ Disable the login banner on stdin and Telnet connections.
+
+ **Example:** cli-no-banner
+
+ * **cli-no-pager**
+ Disable the output pager.
+
+ **Example:** cli-no-pager
+
+ * **cli-pager-buffer-limit <n>**
+ Limit pager buffer to <n> lines of output. A value of 0 disables the
+ pager. Default value: 100000
+
+ **Example:** cli-pager-buffer-limit 5000
+
+ * **runtime-dir <dir>**
+ Set the runtime directory, which is the default location for certain
+ files, like socket files. Default is based on User ID used to start VPP.
+ Typically it is *'root'*, which defaults to *'/run/vpp/'*. Otherwise,
+ defaults to *'/run/user/<uid>/vpp/'*.
+
+ **Example:** runtime-dir /tmp/vpp
+
+ * **poll-sleep-usec <n>**
+ Add a fixed-sleep between main loop poll. Default is 0, which is not to
+ sleep.
+
+ **Example:** poll-sleep-usec 100
+
+ * **pidfile <filename>**
+ Writes the pid of the main thread in the given filename.
+
+ **Example:** pidfile /run/vpp/vpp1.pid
+
+.. _dpdk:
+
+"dpdk" Parameters
+_________________
+
+Command line DPDK configuration controls a number of parameters, including
+device whitelisting, the number of CPUs available for launching
+dpdk-eal-controlled threads, the number of I/O buffers, and the process
+affinity mask. In addition, the DPDK configuration function attempts to support
+all of the DPDK EAL configuration parameters.
+
+All of the DPDK EAL options should be available.
+See ../src/plugins/dpdk/device/dpdk_priv.h, look at the set of
+"foreach_eal_XXX" macros.
+
+Popular options include:
+ * **dev <pci-dev>**
+ White-list [as in, attempt to drive] a specific PCI device. PCI-dev is a
+ string of the form "DDDD:BB:SS.F" where:
+
+ | DDDD = Domain
+ | BB = Bus Number
+ | SS = Slot number
+ | F = Function
+
+ This is the same format used in the linux sysfs tree (i.e.
+ /sys/bus/pci/devices) for PCI device directory names.
+
+ **Example:** dev 0000:02:00.0
+
+ * **dev <pci-dev> { .. }**
+ When whitelisting specific interfaces by specifying PCI address,
+ additional custom parameters can also be specified. Valid options include:
+
+ * **num-rx-queues <n>**
+ Number of receive queues. Also enables RSS. Default value is 1.
+ * **num-tx-queues <n>**
+ Number of transmit queues. Default is equal to number of worker
+ threads or 1 if no workers treads.
+ * **num-rx-desc <n>**
+ Number of descriptors in receive ring. Increasing or reducing number
+ can impact performance. Default is 1024.
+ * **num-rt-desc <n>**
+ Number of descriptors in transmit ring. Increasing or reducing number
+ can impact performance. Default is 1024.
+ * **workers**
+ TBD
+ * **vlan-strip-offload on|off**:
+ VLAN strip offload mode for interface. VLAN stripping is off by default
+ for all NICs except VICs, using ENIC driver, which has VLAN stripping on
+ by default.
+ * **hqos**
+ Enable the Hierarchical Quaity-of-Service (HQoS) scheduler, default is
+ disabled. This enables HQoS on specific output interface.
+ * **hqos { .. }**
+ HQoS can also have its own set of custom parameters. Setting a custom
+ parameter also enables HQoS.
+
+ * **hqos-thread <n>**
+ HQoS thread used by this interface. To setup a pool of threads that
+ are shared by all HQoS interfaces, set via the*'cpu'* section using
+ either *'corelist-hqos-threads'* or *'coremask-hqos-threads'*.
+
+ * **rss**
+ TBD
+
+ **Example:**
+
+ | dev 0000:02:00.1 {
+ | num-rx-queues 2
+ | num-tx-queues 2
+ | }
+
+ * **vdev <eal-command>**
+ Provide a DPDK EAL command to specify bonded Ethernet interfaces, operating
+ modes and PCI addresses of slave links. Only XOR balanced (mode 2) mode is
+ supported.
+
+ **Example:**
+
+ | vdev eth_bond0,mode=2,slave=0000:0f:00.0,slave=0000:11:00.0,xmit_policy=l34
+ | vdev eth_bond1,mode=2,slave=0000:10:00.0,slave=0000:12:00.0,xmit_policy=l34
+
+ * **num-mbufs <n>**
+ Increase number of buffers allocated. May be needed in scenarios with
+ large number of interfaces and worker threads, or a lot of physical
+ interfaces with multiple RSS queues. Value is per CPU socket. Default is
+ 16384.
+
+ **Example:** num-mbufs 128000
+
+ * **no-pci**
+ When VPP is started, if an interface is not owned by the linux kernel
+ (interface is administratively down), VPP will attempt to manage the
+ interface. *'no-pci'* indicates that VPP should not walk the PCI table
+ looking for interfaces.
+
+ **Example:** no-pci
+
+ * **no-hugetlb**
+ Don't use huge TLB pages. Potentially useful for running simulator images.
+
+ **Example:** no-hugetlb
+
+ * **kni <n>**
+ Number of KNI interfaces. Refer to the DPDK documentation.
+
+ **Example:** kni 2
+
+ * **uio-driver uio_pci_generic|igb_uio|vfio-pci|auto**
+ Change UIO driver used by VPP. Default is *'auto'*.
+
+ **Example:** uio-driver igb_uio
+
+ * **socket-mem <n>**
+ Change hugepages allocation per-socket, needed only if there is need for
+ larger number of mbufs. Default is 64 hugepages on each detected CPU
+ socket.
+
+ **Example:** socket-mem 2048,2048
+
+**Other options include:**
+
+ * **enable-tcp-udp-checksum**
+ Enables UDP/TCP RX checksum offload.
+
+ **Example:** enable-tcp-udp-checksum
+
+ * **no-multi-seg**
+ Disable mutli-segment buffers, improves performance but disables Jumbo MTU
+ support.
+
+ **Example:** no-multi-seg
+
+ * **no-tx-checksum-offload**
+ Disables UDP/TCP TX checksum offload. Typically needed for use faster
+ vector PMDs (together with no-multi-seg).
+
+ **Example:** no-tx-checksum-offload
+
+ * **decimal-interface-names**
+ Format DPDK device names with decimal, as opposed to hexadecimal.
+
+ **Example:** decimal-interface-names
+
+ * **log-level emergency|alert|critical|error|warning|notice|info|debug**
+ Set the log level for DPDK logs. Default is *'notice'*.
+
+ **Example:** log-level error
+
+ * **dev default { .. }**
+ Change default settings for all intefaces. This sections supports the
+ same set of custom parameters described in *'dev <pci-dev> { .. }*'.
+
+ **Example:**
+
+ | dev default {
+ | num-rx-queues 3
+ | num-tx-queues 3
+ | }
+
+.. _cpu:
+
+"cpu" Parameters
+________________
+
+Command-line CPU configuration controls the creation of named thread types, and
+the cpu affinity thereof. In the VPP there is one main thread and optionally
+the user can create worker(s). The main thread and worker thread(s) can be
+pinned to CPU core(s) automatically or manually.
+
+**Automatic Pinning:**
+
+ * **workers <n>**
+ Create <n> worker threads.
+
+ **Example:** workers 4
+
+ * **io <n>**

+ on the *'scheduler-policy'* and the current kernel version running. The
+ range is typically 1 to 99, but see the linux man pages for *'sched'* for
+ more details. If this value is not set, the current linux kernel default
+ is left in place.
+
+ **Example:** scheduler-priority 50
+
+ * **<thread-name> <count>**
+ Set the number of threads for a given thread (by name). Some threads, like
+ *'stats'*, have a fixed number of threads and cannot be changed. List of

+
+ **Example:** hqos-threads 2
+
+.. note::
+

+
+
+.. _acl-plugin:
+
+"acl-plugin" Parameters
+_______________________
+
+The following parameters should only be set by those that are familiar with the
+interworkings of VPP and the ACL Plugin.
+
+The first three parameters, *connection hash buckets*, *connection hash memory*, and *connection count max*, set the **connection table per-interface parameters** for modifying how the two bounded-index extensible hash tables for IPv6 (40\*8 bit key and 8\*8 bit value pairs) and IPv4 (16\*8 bit key and 8\*8 bit value pairs) **ACL plugin FA interface sessions** are initialized.
+
+ * **connection hash buckets <n>**
+ Sets the number of hash buckets (rounded up to a power of 2) in each of the two bi-hash tables. Defaults to 64\*1024 (65536) hash buckets.
+
+ **Example:** connection hash buckets 65536
+
+ * **connection hash memory <n>**
+ Sets the number of bytes used for “backing store” allocation in each of the two bi-hash tables. Defaults to 1073741824 bytes.
+
+ **Example:** connection hash memory 1073741824
+
+ * **connection count max <n>**
+ Sets the maximum number of pool elements when allocating each per-worker pool of sessions for both bi-hash tables. Defaults to 500000 elements in each pool.
+
+ **Example:** connection count max 500000
+
+ * **main heap size <n>G|<n>M|<n>K|<n>**
+ Sets the size of the main memory heap that holds all the ACL module related allocations (other than hash.) Default size is 0, but during ACL heap initialization is equal to *per_worker_size_with_slack * tm->n_vlib_mains + bihash_size + main_slack*. Note that these variables are partially based on the **connection table per-interface parameters** mentioned above.
+
+ **Example:** main heap size 3G
+
+The next three parameters, *hash lookup heap size*, *hash lookup hash buckets*, and *hash lookup hash memory*, modify the initialization of the bi-hash lookup table used by the ACL plugin. This table is initialized when attempting to apply an ACL to the existing vector of ACLs looked up during packet processing (but it is found that the table does not exist / has not been initialized yet.)
+
+ * **hash lookup heap size <n>G|<n>M|<n>K|<n>**
+ Sets the size of the memory heap that holds all the miscellaneous allocations related to hash-based lookups. Default size is 67108864 bytes.
+
+ **Example:** hash lookup heap size 70M
+
+ * **hash lookup hash buckets <n>**
+ Sets the number of hash buckets (rounded up to a power of 2) in the bi-hash lookup table. Defaults to 65536 hash buckets.
+
+ **Example:** hash lookup hash buckets 65536
+
+ * **hash lookup hash memory <n>**
+ Sets the number of bytes used for “backing store” allocation in the bi-hash lookup table. Defaults to 67108864 bytes.
+
+ **Example:** hash lookup hash memory 67108864
+
+ * **use tuple merge <n>**
+ Sets a boolean value indicating whether or not to use TupleMerge for hash ACL's. Defaults to 1 (true), meaning the default implementation of hashing ACL's **does use** TupleMerge.
+
+ **Example:** use tuple merge 1
+
+ * **tuple merge split threshold <n>**
+ Sets the maximum amount of rules (ACE's) that can collide in a bi-hash lookup table before the table is split into two new tables. Splitting ensures less rule collisions by hashing colliding rules based on their common tuple (usually their maximum common tuple.) Splitting occurs when the *length of the colliding rules vector* is greater than this threshold amount. Defaults to a maximum of 39 rule collisions per table.
+
+ **Example:** tuple merge split threshold 30
+
+ * **reclassify sessions <n>**
+ Sets a boolean value indicating whether or not to take the epoch of the session into account when dealing with re-applying ACL's or changing already applied ACL's. Defaults to 0 (false), meaning the default implementation **does NOT** take the epoch of the session into account.
+
+ **Example:** reclassify sessions 1
+
+.. _api-queue:

+________________________
+
+These values control various aspects of the binary API interface to VPP.
+
+ * **prefix <path>**
+ Sets the prefix prepended to the name used for shared memory (SHM)
+ segments. The default is empty, meaning shared memory segments are created
+ directly in the SHM directory *'/dev/shm'*. It is worth noting that on
+ many systems *'/dev/shm'* is a symbolic link to somewhere else in the file
+ system; Ubuntu links it to *'/run/shm'*.
+
+ **Example:** prefix /run/shm
+
+ * **uid <number|name>**
+ Sets the user ID or name that should be used to set the ownership of the
+ shared memory segments. Defaults to the same user that VPP is started
+ with, probably root.
+
+ **Example:** uid root
+
+ * **gid <number|name>**
+ Sets the group ID or name that should be used to set the ownership of the
+ shared memory segments. Defaults to the same group that VPP is started
+ with, probably root.
+
+ **Example:** gid vpp
+
+The following parameters should only be set by those that are familiar with the
+interworkings of VPP.
+
+ * **baseva <x>**
+ Set the base address for SVM global region. If not set, on AArch64, the

+ **Example:** global-pvt-heap-size size 262144
+
+ * **api-pvt-heap-size <n>M|size <n>**
+ Set the size of the api private mheap. If not set, defaults to 128k.

+
+ **Example:** api-pvt-heap-size 1M
+
+ * **api-size <n>M|<n>G|<n>**

+ value can be set in GB, MB or bytes.
+
+ **Example:** api-size 64M
+
+.. _api-trace:
+
+"api-trace" Parameters

+ and unless there is a very strong reason, it should remain enabled.
+
+ **Example:** on
+
+ * **nitems <n>**

+
+ **Example:** TBD
+
+.. _tuntap:
+
+"tuntap" Parameters
+___________________
+
+The "tuntap" driver configures a point-to-point interface between the vpp
+engine and the local Linux kernel stack. This allows e.g. users to ssh to the
+host | VM | container via vpp "revenue" interfaces. It's marginally useful, and
+is currently disabled by default. To [dynamically] create TAP interfaces - the
+preferred scheme - see the "tap_connect" binary API. The Linux network stack
+"vnet" interface needs to manually configure, and VLAN and other settings if
+desired.
+
+ * **enable|disable**
+ Enable or disable the tun/tap driver.
+
+ **Example:** enable
+
+ * **ethernet|ether**
+ Create a tap device (ethernet MAC) instead of a tun device (point-to-point
+ tunnel). The two keywords are aliases for the same function.
+
+ **Example:** ethernet
+
+ * **have-normal-interface|have-normal**
+ Treat the host Linux stack as a routing peer instead of programming VPP
+ interface L3 addresses onto the tun/tap devices. The two keywords are
+ aliases for the same function.
+
+ **Example:** have-normal-interface
+
+ * **name <name>**
+ Assign name to the tun/tap device.
+
+ **Example:** name vpp1
+
+Here's a typical multiple parameter invocation:
+
+ | tuntap { ethernet have-normal-interface name vpp1 }
+
+.. _vhost-user:
+
+"vhost-user" Parameters
+_______________________
+
+Vhost-user configuration parameters control the vhost-user driver.
+
+ * **coalesce-frames <n>**
+ Subject to deadline-timer expiration - see next item - attempt to transmit
+ at least <n> packet frames. Default is 32 frames.
+
+ **Example:** coalesce-frames 64
+
+ * **coalesce-time <seconds>**
+ Hold packets no longer than (floating-point) seconds before transmitting
+ them. Default is 0.001 seconds
+
+ **Example:** coalesce-time 0.002
+
+ * **dont-dump-memory**
+ vhost-user shared-memory segments can add up to a large amount of memory, so
+ it's handy to avoid adding them to corefiles when using a significant number
+ of such interfaces.
+
+ **Example:** dont-dump-memory
+
+.. _vlib:
+
+"vlib" Parameters
+_________________
+
+ * **memory-trace**
+ TBD

+Dry Run
+*******
+
+With the config utility dry run option the important configuration files are created
+so that the user can examine them and then if they look reasonable apply them with
+option 3. The files for **Ubuntu** can be found in the root directory /usr/local/vpp/vpp-config/dryrun
+and for **Centos** in /usr/vpp/vpp-config/dryrun.
+
+The important configuration files are **/etc/vpp/startup.conf**, **/etc/sysctl.d/80-vpp.conf**,
+and **/etc/default/grub**
+
+Startup.conf
+============
+
+FD.io VPP startup parameters are configured in the file **/etc/vpp/startup.conf**. The
+utility creates this file under the vpp-config root directory in vpp/startup.conf.
+the values in this file come from the questions asked about the devices, cores, rx queues,
+and tcp parameters.
+
+80-vpp.conf
+===========
+
+The huge page configuration comes by setting values in the file **/etc/sysctl.d/80-vpp.conf**.
+The utility creates the file under the root directory in sysctl.d/80-vpp.conf. When asked the
+question about huge pages the correct values are put in the dryrin file.
+
+grub
+====
+
+CPUs can be isolated for use by VPP or other processes such as VMs using the grub configuration
+file. This file is **/etc/default/grub**. This file must be modified with care. It is possible to
+make your system unusable if this file is modified incorrectly. The dry run file is located under
+the vpp-config root directory and then default.
+

+VPP Configuration Utility
+#########################
+
+This guide provides instructions on how to install and use the vpp configuration
+utility.
+
+The FD.io VPP Configuration Utility, or vpp-config, allows the user to configure
+FD.io VPP in a simple and safe manner. The utility takes input from the user and
+creates the configuration files in a dry run directory. The user should then examine
+these files for correctness. If the configuration files look correct, the user
+can then apply the configuration. Once the configuration is applied the user
+should then check the system configuration with the utility and see if it was
+applied correctly.
+
+This utility also includes a utility that can be used to install or uninstall FD.io VPP
+packages. This should be used to insure the latest tested release is installed.

+
+CPU
+---
+
+The CPU section of the system information is a summary of the CPU characteristics of the system.
+It is important to understand the CPU topology and frequency in order to understand what the VPP
+performance characteristics would be.
+
+Threads
+-------
+
+It usually is not needed, but VPP can be configured to run on isolated CPUs. In the example shown
+VPP is configured with 2 workers. The main thread is also configured to run on a seperate CPU. The
+stats thread will always run on CPU 0. This utilty will put the worker threads on CPUs that are
+associated with the ports that are configured.
+
+Grub Command Line
+-----------------
+
+In general the Grub command line does not need to be changed. If the system is running many processes
+it may be neccessary to isolate CPUs for VPP or other processes.
+
+Huge Pages
+----------
+
+As default when VPP is configured the number of huge pages that will be configured will be 1024.
+This may not be enough. This section will show the total system memory and how many are configured.
+
+
+Devices
+-------
+
+In the devices section we have the "Total Number of Buffers". This utility allocates the correct
+number of buffers. The number of buffers are calculated from the number of rx queues.
+
+VPP will not use links that are up. Those devices are shown with this utility.
+
+The devices bound to the kernel are not being used by VPP, but can be.
+
+The devices that are being used by VPP are shown with the interface name be used with VPP. The
+socket being used by the VPP port is also shown. Notice in this example the worker thread are
+on the correct CPU. The number of RX, TX Descriptors and TX queues are calculated from the number
+of RX queues.
+
+
+VPP Service Status
+------------------
+
+The VPP service status, will be installed, not installed, running or not.

+Setup the fd.io Repository - Centos 7
+=====================================
+
+Update the OS
+-------------
+
+It is probably a good idea to update and upgrade the OS before starting:
+
+.. code-block:: console
+
+ $ sudo yum update
+
+
+Point to the Repository
+-----------------------
+
+For CentOS based systems, there are two respositories to pull VPP binaries
+from.
+
+* CentOS NFV SIG Repository
+* Nexus Repository
+
+
+CentOS NFV SIG Repository
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+VPP is not in the official CentOS 7 distro. However, CentOS has Special
+Interest Groups (SIG), which are smaller groups within the CentOS community that
+focus on a small set of issues. The CentOS NFV (Network Function Virtualization)
+SIG was created to provide a CentOS-based stack that will serve as a platform
+for the deployment and testing of virtual network functions (VNFs). VPP has been
+included in this SIG.
+
+To install released packages from the CentOS NFV SIG Repository on an updated
+Centos 7 system, first, install the CentOS NFV SIG FIDO repo file:
+
+.. code-block:: console
+
+ $ sudo yum install centos-release-fdio
+
+then **'Install VPP RPMs'**, as described below.
+
+This will install the latest VPP version from the repository. To install an
+older version, once the CentOS NFV SIG FDIO repo file has been installed, list
+the stored versions:
+
+.. code-block:: console
+
+ $ sudo yum --showduplicates list vpp* | expand
+ Loaded plugins: fastestmirror
+ Loading mirror speeds from cached hostfile
+ * base: repos-va.psychz.net

+
+.. code-block:: console
+
+ $ sudo yum install vpp-17.10-1.x86_64
+
+
+Nexus Repository
+^^^^^^^^^^^^^^^^
+
+Build artifacts are also posted to a FD.io Nexus Repository. This includes
+official point releases, as well as nightly builds. To use any of these build
+artifacts, create a file *'/etc/yum.repos.d/fdio-release.repo'* with the
+content that points to the version needed. Below are some common examples of
+the content needed:
+
+
+VPP Latest Release
+""""""""""""""""""
+
+To allow *'yum'* access to the official VPP releases, create the file
+*'/etc/yum.repos.d/fdio-release.repo'* with the following content:
+
+.. code-block:: console
+
+ $ cat /etc/yum.repos.d/fdio-release.repo
+ [fdio-release]
+ name=fd.io release branch latest merge
+ baseurl=https://nexus.fd.io/content/repositories/fd.io.centos7/
+ enabled=1
+ gpgcheck=0
+
+The *'yum install vpp'* command will install the most recent release. To
+install older releases, run the following command to get the list of releases
+provided:
+
+.. code-block:: console
+
+ $ sudo yum --showduplicates list vpp* | expand
+
+Then choose the release to install. See **'CentOS NFV SIG Repository'** for
+sample *'yum --showduplicates list'* output and an example of installing a
+particular version of the RPMs.
+
+VPP Stable Branch
+"""""""""""""""""
+
+To allow *yum* access to the build artifacts for a VPP stable branch, create
+the file *'/etc/yum.repos.d/fdio-release.repo'* with the following content:
+
+.. code-block:: console
+
+ $ cat /etc/yum.repos.d/fdio-release.repo
+ [fdio-stable-1804]
+ name=fd.io stable/1804 branch latest merge
+ baseurl=https://nexus.fd.io/content/repositories/fd.io.stable.1804.centos7/
+ enabled=1
+ gpgcheck=0
+
+For other stable branches, replace the *'1804'* from the above content with the
+desired release. Examples: 1606, 1609, 1701, 1704, 1707, 1710, 1804, 1807
+
+The *'yum install vpp'* command will install the most recent build on the
+branch, not the latest offical release. Run the following command to get the
+list of images produce by the branch:
+
+.. code-block:: console
+
+ $ sudo yum --showduplicates list vpp* | expand
+
+Then choose the image to install. See **'CentOS NFV SIG Repository'** for
+sample *'yum --showduplicates list'* output and an example of installing a
+particular version of the RPMs.
+
+
+VPP Master Branch
+"""""""""""""""""
+
+To allow *yum* access to the nightly builds from the VPP master branch, create
+the file *'/etc/yum.repos.d/fdio-release.repo'* with the following content:
+
+.. code-block:: console
+
+ $ cat /etc/yum.repos.d/fdio-release.repo
+ [fdio-master]
+ name=fd.io master branch latest merge
+ baseurl=https://nexus.fd.io/content/repositories/fd.io.master.centos7/
+ enabled=1
+ gpgcheck=0
+
+The *'yum install vpp'* command will install the most recent build on the
+branch. Run the following command to get the list of images produce by the
+branch:
+
+.. code-block:: console
+
+ $ sudo yum --showduplicates list vpp* | expand
+
+Then choose the image to install. See **'CentOS NFV SIG Repository'** for
+sample *'yum --showduplicates list'* output and an example of installing a
+particular version of the RPMs.
+
+
+Install VPP RPMs
+================
+
+To install the VPP packet engine, run the following:
+
+.. code-block:: console
+
+ $ sudo yum install vpp
+
+The **'vpp'** RPM depend on the **'vpp-lib'** and **'vpp-selinux-policy'**
+RPMs, so they will be installed as well.
+
+.. note::
+
+ The **'vpp-selinux-policy'** will not enable SELinux on the system. It
+ will install a Custom VPP SELinux policy that will be used if SELinux is
+ enabled at any time.
+
+There are additional packages that are optional. These packages can be
+combined with the command above and installed all at once, or installed as
+needed:
+
+.. code-block:: console
+
+ $ sudo yum install vpp-plugins vpp-devel vpp-api-python vpp-api-lua vpp-api-java
+
+Starting VPP
+============
+
+Once VPP is installed on the system, to run VPP as a systemd service on CentOS,
+run:
+
+.. code-block:: console
+
+ $ sudo systemctl start vpp
+
+Then to enable VPP to start on system reboot:
+
+.. code-block:: console
+
+ $ sudo systemctl enable vpp
+
+
+Outside of running VPP as a systemd service, VPP can be started manually or
+made to run within GDB for debugging. See :ref:`running` for more details and
+ways to tailor VPP to a specific system.
+
+
+Uninstall the VPP RPMs
+======================
+
+.. code-block:: console
+
+ $ sudo yum autoremove vpp*

+**********************
+Building VPP Documents
+**********************
+
+Overview
+========
+
+These instructions show how the VPP documentation sources are built.
+
+FD.io VPP Documentation uses `reStructuredText <http://www.sphinx-doc.org/en/master/usage/restructuredtext/index.html>`_ (rst) files, which are used by `Sphinx <http://www.sphinx-doc.org/en/master/>`_.
+We will also cover how to view your build on Read the Docs in `Using Read the Docs`_.
+
+
+To build your files, you can either `Create a Virtual Environment using virtualenv`_, which installs all the required applications for you, or you can `Install Sphinx manually`_.
+
+Create a Virtual Environment using virtualenv
+_____________________________________________
+
+For more information on how to use the Python virtual environment check out
+`Installing packages using pip and virtualenv`_.
+
+.. _`Installing packages using pip and virtualenv`: https://packaging.python.org/guides/installing-using-pip-and-virtualenv/
+
+Get the Documents
+^^^^^^^^^^^^^^^^^
+
+For example start with a clone of the vpp-docs.
+
+.. code-block:: console
+
+ $ git clone https://gerrit.fd.io/r/vpp
+ $ cd vpp
+
+
+Install the virtual environment
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+In your vpp-docs directory, run:
+
+.. code-block:: console
+
+ $ python -m pip install --user virtualenv
+ $ python -m virtualenv env
+ $ source env/bin/activate
+ $ pip install -r docs/etc/requirements.txt
+ $ cd docs
+
+Which installs all the required applications into it's own, isolated, virtual environment, so as to not
+interfere with other builds that may use different versions of software.
+
+Build the html files
+^^^^^^^^^^^^^^^^^^^^
+
+Be sure you are in your vpp-docs/docs directory, since that is where Sphinx will look for your **conf.py**
+file, and build the **.rst** files into an **index.html** file:
+
+.. code-block:: console
+
+ $ make html
+
+View the results
+^^^^^^^^^^^^^^^^
+
+| If there are no errors during the build process, you should now have an **index.html** file in your
+| **vpp/docs/_build/html** directory, which you can then view in your browser.
+
+.. figure:: /_images/htmlBuild.png
+ :alt: Figure: My directory containing the index.html file
+ :scale: 35%
+ :align: center
+
+Whenever you make changes to your **.rst** files that you want to see, repeat this build process.
+
+.. note::
+
+ To exit from the virtual environment execute:
+
+.. code-block:: console
+
+ $ deactivate
+
+
+Install Sphinx manually
+_______________________
+
+Skip this step if you created a *virtualenv* in the previous step. If you dont want to create a *virtualenv*, you should install Sphinx `here <http://www.sphinx-doc.org/en/master/usage/installation.html>`_, and follow their `getting started guide <http://www.sphinx-doc.org/en/master/usage/quickstart.html>`_.
+
+Building these files will generate an **index.html** file, which you can then view in your browser to verify and see your file changes.
+
+
+To *build* your files, make sure you're in your **vpp-docs/docs** directory, where your **conf.py** file is located, and run:
+
+.. code-block:: console
+
+ $ make html
+
+
+| If there are no errors during the build process, you should now have an **index.html** file in your
+| **vpp-docs/docs/_build/html** directory, which you can then view in your browser.
+
+.. figure:: /_images/htmlBuild.png
+ :scale: 35%
+ :align: center
+
+Whenever you make changes to your **.rst** files that you want to see, repeat this build process.
+
+
+Using Read the Docs
+___________________
+
+`Read the Docs <https://readthedocs.org/>`_ is a website that "simplifies software documentation by automating building, versioning, and hosting of your docs for you". Essentially, it accesses your Github repo to generate the **index.html** file, and then displays it on its own *Read the Docs* webpage so others can view your documentation.
+
+Create an account on *Read the Docs* if you haven't already.
+
+Go to your `dashboard <https://readthedocs.org/dashboard/>`_ , and click on "Import a Project".
+
+.. figure:: /_images/importReadDocs.png
+ :scale: 35%
+ :align: left
+
+ This will bring you to a page where you can choose to import a repo from your Github account (only if you've linked your Github account to your Read the Docs account), or to import a repo manually. In this example, we'll do it manually. Click "Import Manually".
+
+|
+|
+|
+|
+|
+|
+|
+
+
+
+This will bring you to a page that asks for your repo details. Set "Name" to your forked repo name, or whatever you want. Set "Repository URL" to the URL of your forked repo (https://github.com/YOURUSERNAME/vpp-docs). "Repository type" should already be selected to "Git". Then click "Next".
+
+
+.. figure:: /_images/importRTDManually.png

+|
+|

+|
+|
+|
+|
+|
+|
+|
+|
+|
+|
+|
+|
+|
+|
+|
+
+
+This will bring you to a project page of your repo on Read the Docs. You can confirm it's the correct repo by checking on the right side of the page the Repository URL.
+
+Then click on "Build Version".
+
+.. figure:: /_images/buildVerRTD.png

+|
+|
+|
+|
+|
+|
+|
+|
+|
+|
+|
+|
+|
+|
+
+Which takes you to another page showing your recent builds.
+
+Then click on "Build Version:". This should "Trigger" a build. After about a minute or so you can refresh the page and see that your build "Passed".

+=================
+Github Repository
+=================
+
+**The github repository is no longer being used. The gerrit server is being used.**
+
+To use the gerrit repository refer to :ref:`gitreview`.
+
+Overview
+________
+
+This section will cover how to fork your own branch of the `fdioDocs/vpp-docs <https://github.com/fdioDocs/vpp-docs>`_ repository, clone that repo locally to your computer, make changes to it, and how to issue a pull request when you want your changes to be reflected on the main repo.
+
+.. toctree::
+
+Forking your own branch
+_______________________
+
+In your browser, navigate to the repo you want to branch off of. In this case, the `fdioDocs/vpp-docs <https://github.com/fdioDocs/vpp-docs>`_ repo. At the top right of the page you should see this:
+
+.. figure:: /_images/ForkButtons.png
+ :alt: Figure: Repository options on Github
+ :scale: 50%
+ :align: right
+
+|
+|
+|
+
+Click on "Fork", and then a pop-up should appear where you should then click your Github username. Once this is done, it should automatically take you to the Github page where your new branch is located, just like in the image below.
+
+.. figure:: /_images/usernameFork.png
+ :alt: Figure: Your own branch of the main repo on Github
+ :scale: 35%
+ :align: center
+
+
+Now your **own branch** can be **cloned** to your computer using the URL (https://github.com/YOURUSERNAME/vpp-docs) of the Github page where your branch is located.
+
+
+Creating a local repository
+___________________________
+
+Now that you have your own branch of the main repository on Github, you can store it locally on your computer. In your shell, navigate to the directory where you want to store your branch/repo. Then execute:
+
+.. code-block:: console
+
+ $ git clone https://github.com/YOURUSERNAME/vpp-docs
+
+This will create a directory on your computer named **vpp-docs**, the name of the repo.
+
+Now that your branch is on your computer, you can modify and build files however you wish.
+
+If you are not on the master branch, move to it.
+
+.. code-block:: console
+
+ $ git checkout master
+
+
+Keeping your files in sync with the main repo
+_____________________________________________
+
+The following talks about remote branches, but keep in mind that there are currently *two* branches, your local "master" branch (on your computer), and your remote "origin or origin/master" branch (the one you created using "Fork" on the Github website).
+
+You can view your *remote* repositories with:
+
+.. code-block:: console
+
+ $ git remote -v
+
+At this point, you may only see the remote branch that you cloned from.
+
+.. code-block:: console
+
+ Macintosh:docs Andrew$ git remote -v
+ origin https://github.com/a-olechtchouk/vpp-docs (fetch)
+ origin https://github.com/a-olechtchouk/vpp-docs (push)
+
+Now you want to create a new remote repository of the main vpp-docs repo (naming it upstream).
+
+.. code-block:: console
+
+ $ git remote add upstream https://github.com/fdioDocs/vpp-docs
+
+
+You can verify that you have added a remote repo using the previous **git remote -v** command.
+
+.. code-block:: console
+
+ $ git remote -v
+ origin https://github.com/a-olechtchouk/vpp-docs (fetch)
+ origin https://github.com/a-olechtchouk/vpp-docs (push)
+ upstream https://github.com/fdioDocs/vpp-docs (fetch)
+ upstream https://github.com/fdioDocs/vpp-docs (push)
+
+
+If there have been any changes to files in the main repo (hopefully not the same files you were working on!), you want to make sure your local branch is in sync with them.
+
+To do so, fetch any changes that the main repo has made, and then merge them into your local master branch using:
+
+.. code-block:: console
+
+ $ git fetch upstream
+ $ git merge upstream/master
+
+
+.. note:: **This is optional, so don't do these commands if you just want one local branch!!!**
+
+ You may want to have multiple branches, where each branch has its own different features, allowing you to have multiple pull requests out at a time. To create a new local branch:
+
+.. code-block:: shell
+
+ $ git checkout -b cleanup-01
+ $ git branch
+ * cleanup-01
+ master
+ overview
+
+ Now you can redo the previous steps for "Keeping your files in sync with the main repo" for your newly created local branch, and then depending on which branch you want to send out a pull reqest for, proceed below.
+
+
+Pushing to your branch
+______________________
+
+Now that your files are in sync, you want to add modified files, commit, and push them from *your local branch* to your *personal remote branch* (not the main fdioDocs repo).
+
+To check the status of your files, run:
+
+.. code-block:: console
+
+ $ git status
+
+
+In the output example below, I deleted gettingsources.rst, made changes to index.rst and pushingapatch.rst, and have created a new file called buildingrst.rst.
+
+.. code-block:: console
+
+ Macintosh:docs Andrew$ git status
+ On branch master
+ Your branch is up-to-date with 'origin/master'.
+ Changes to be committed:
+ (use "git reset HEAD <file>..." to unstage)
+
+ deleted: tasks/writingdocs/gettingsources.rst
+
+ Changes not staged for commit:
+ (use "git add <file>..." to update what will be committed)
+ (use "git checkout -- <file>..." to discard changes in working directory)
+
+ modified: tasks/writingdocs/index.rst
+ modified: tasks/writingdocs/pushingapatch.rst
+
+ Untracked files:
+ (use "git add <file>..." to include in what will be committed)
+
+ tasks/writingdocs/buildingrst.rst
+
+
+
+To add files (use **git add -A** to add all modified files):
+
+.. code-block:: console
+
+ $ git add FILENAME1 FILENAME2
+
+Commit and push using:
+
+.. code-block:: console
+
+ $ git commit -m 'A descriptive commit message for two files.'
+
+Push your changes for the branch where your changes were made
+
+.. code-block:: console
+
+ $ git push origin <branch name>
+
+Here, your personal remote branch is "origin" and your local branch is "master".
+
+.. note::
+
+ Using **git commit** after adding your files saves a "Snapshot" of them, so it's very hard to lose your work if you *commit often*.
+
+
+
+Initiating a pull request (Code review)
+_______________________________________
+
+Once you've pushed your changes to your remote branch, go to your remote branch on Github (https://github.com/YOURUSERNAME/vpp-docs), and click on "New pull request".
+
+.. figure:: /_images/issuePullReq.png
+ :alt: Figure: Your own branch of the main repo on Github
+ :scale: 35%
+ :align: center
+
+This will bring you to a "Comparing changes" page. Click "Create new pull request".
+
+.. figure:: /_images/createNewPullReq.png
+ :scale: 35%
+ :align: left
+
+|
+|
+|
+
+Which will open up text fields to add information to your pull request.
+
+.. figure:: /_images/examplePullReq.png
+ :scale: 35%
+ :align: center
+
+
+ Then finally click "Create pull request" to complete the pull request.
+
+Your documents will be reviewed. To this same branch make the changes requested from the review and then push your new changes. There is no need to create another pull request.
+
+.. code-block:: console
+
+ $ git commit -m 'A descriptive commit message for the new changes'
+ $ git push origin <branch name>
+
+
+Additional Git commands
+_______________________
+
+You may find some of these Git commands useful:
+
+Use **git diff** to quickly show the file changes and repo differences of your commits.
+
+Use **git rm FILENAME** to stop tracking a file and to remove it from your remote branch and local directory. Use flag **-r** to remove folders/directories. E.g (**git rm -r oldfolder**)

+Tables
+******
+
+There are two types of tables with different syntax, `Grid Tables <http://docutils.sourceforge.net/docs/ref/rst/restructuredtext.html#grid-tables>`_, and `Simple Tables <http://docutils.sourceforge.net/docs/ref/rst/restructuredtext.html#simple-tables>`_.
+
+Grid Tables
+___________
+
+`Grid Tables <http://docutils.sourceforge.net/docs/ref/rst/restructuredtext.html#grid-tables>`_ are described with a visual grid made up of the characters "-", "=", "|", and "+". The hyphen ("-") is used for horizontal lines (row separators). The equals sign ("=") may be used to separate optional header rows from the table body. The vertical bar ("|") is used for vertical lines (column separators). The plus sign ("+") is used for intersections of horizontal and vertical lines.
+
+Here is example code for a grid table in a *.rst* file:
+
+.. code-block:: console
+
+ +------------------------+------------+----------+----------+
+ | Header row, column 1 | Header 2 | Header 3 | Header 4 |
+ | (header rows optional) | | | |
+ +========================+============+==========+==========+
+ | body row 1, column 1 | column 2 | column 3 | column 4 |
+ +------------------------+------------+----------+----------+
+ | body row 2 | Cells may span columns. |
+ +------------------------+------------+---------------------+
+ | body row 3 | Cells may | - Table cells |
+ +------------------------+ span rows. | - contain |
+ | body row 4 | | - body elements. |
+ +------------------------+------------+---------------------+
+
+This example code generates a grid table that looks like this:
+
++------------------------+------------+----------+----------+
+| Header row, column 1 | Header 2 | Header 3 | Header 4 |
+| (header rows optional) | | | |
++========================+============+==========+==========+
+| body row 1, column 1 | column 2 | column 3 | column 4 |
++------------------------+------------+----------+----------+
+| body row 2 | Cells may span columns. |
++------------------------+------------+---------------------+
+| body row 3 | Cells may | - Table cells |
++------------------------+ span rows. | - contain |
+| body row 4 | | - body elements. |
++------------------------+------------+---------------------+
+
+
+Simple Tables
+_____________
+
+`Simple tables <http://docutils.sourceforge.net/docs/ref/rst/restructuredtext.html#simple-tables>`_ are described with horizontal borders made up of "=" and "-" characters. The equals sign ("=") is used for top and bottom table borders, and to separate optional header rows from the table body. The hyphen ("-") is used to indicate column spans in a single row by underlining the joined columns, and may optionally be used to explicitly and/or visually separate rows.
+
+Simple tables are "simpler" to create than grid tables, but are more limited.
+
+Here is example code for a simple table in a *.rst* file.
+
+.. code-block:: console
+
+ ===== ===== =======
+ A B A and B
+ ===== ===== =======
+ False False False
+ True False False
+ False True False
+ True True True
+ ===== ===== =======
+
+This example code generates a simple table that looks like this:
+
+===== ===== =======
+ A B A and B
+===== ===== =======
+False False False
+True False False
+False True False
+True True True
+===== ===== =======

+Introduction
+---------------
+
+This tutorial is designed for you to be able to run it on a single Ubuntu 16.04 VM on your laptop.
+It walks you through some very basic vpp senarios, with a focus on learning vpp commands, doing common actions,
+and being able to discover common things about the state of a running vpp.
+
+This is *not* intended to be a 'how to run in a production environment' set of instructions.
+
+Exercise: Setting up your environment
+-------------------------------------
+
+All of these exercises are designed to be performed on an Ubuntu 16.04 (Xenial) box.
+
+If you have an Ubuntu 16.04 box on which you have sudo, you can feel free to use that.
+
+If you do not, a Vagrantfile is provided to setup a basic Ubuntu 16.04 box for you

+Exercise: Install VPP
+---------------------
+**Skills to be Learned**
+
+ * Learn how to install vpp binary packges using apt-get.
+
+Follow the instructions at :ref:`Installing VPP Binaries <install_vpp>` for installing xenial vpp packages from the release repo. Please note, certain aspects of this tutorial require vpp 17.10 or later.
+
+Exercise: VPP basics
+---------------------
+**Skills to be Learned**
+
+By the end of the exercise you should be able to:
+
+* Run a vpp instance in a mode which allows multiple vpp processes to run
+* Issue vpp commands from the unix shell
+* Run a vpp shell and issue it commands
+
+
+VPP command learned in this exercise
+--------------------------------------

+* `show ver <https://docs.fd.io/vpp/17.04/clicmd_src_vpp_app.html#clicmd_show_version>`_
+
+Action: Remove dpdk plugin
+--------------------------
+In this tutorial, we will be running multiple vpp instances. DPDK does not work well with multiple instances, and so to run multiple instances we will need to disable the dpdk-plugin by removing it:
+
+.. code-block:: console
+
+ sudo rm -rf /usr/lib/vpp_plugins/dpdk_plugin.so
+
+..how-to-run-vpp:
+
+Action: Run VPP
+-----------------
+
+VPP runs in userspace. In a production environment you will often run it with DPDK to connect to real NICs or vhost to connect to VMs.
+In those circumstances you usually run a single instance of vpp.
+
+For purposes of this tutorial, it is going to be extremely useful to run multiple instances of vpp, and connect them to each other to form
+a topology. Fortunately, vpp supports this.
+
+When running multiple vpp instances, each instance needs to have specified a 'name' or 'prefix'. In the example below, the 'name' or 'prefix' is "vpp1". Note that only one instance can use the dpdk plugin, since this plugin is trying to acquire a lock on a file.
+
+.. code-block:: console
+
+ sudo vpp unix {cli-listen /run/vpp/cli-vpp1.sock} api-segment { prefix vpp1 }
+
+**Example Output:**
+
+.. code-block:: console
+
+ vlib_plugin_early_init:230: plugin path /usr/lib/vpp_plugins
+
+Please note:
+
+* "api-segment {prefix vpp1}" tells vpp how to name the files in /dev/shm/ for your vpp instance differently from the default.
+* "unix {cli-listen /run/vpp/cli-vpp1.sock}" tells vpp to use a non-default socket file when being addressed by vppctl.
+
+If you can't see the vpp process running on the host, activate the nodaemon option to better understand what is happening
+
+.. code-block:: console
+
+ sudo vpp unix {nodaemon cli-listen /run/vpp/cli-vpp1.sock} api-segment { prefix vpp1 }
+
+**Example Output with errors from the dpdk plugin:**

+ EAL: Error - exiting with code: 1
+ Cause: Cannot create lock on '/var/run/.vpp_config'. Is another primary process running?
+
+Action: Send commands to VPP using vppctl
+---------------------------------------------------------------
+
+You can send vpp commands with a utility called *vppctl*.
+
+When running vppctl against a named version of vpp, you will need to run:
+
+.. code-block:: console
+
+ sudo vppctl -s /run/vpp/cli-${name}.sock ${cmd}
+
+**Note**
+
+.. code-block:: console
+
+ /run/vpp/cli-${name}.sock
+
+is the particular naming convention used in this tutorial. By default you can set vpp to use what ever socket file name you would like at startup (the default config file uses /run/vpp/cli.sock) if two different vpps are being run (as in this tutorial) you must use distinct socket files for each one.
+
+So to run 'show ver' against the vpp instance named vpp1 you would run:
+
+.. code-block:: console
+
+ sudo vppctl -s /run/vpp/cli-vpp1.sock show ver
+
+**Output:**
+
+.. code-block:: console
+
+ vpp v17.04-rc0~177-g006eb47 built by ubuntu on fdio-ubuntu1604-sevt at Mon Jan 30 18:30:12 UTC 2017
+
+Action: Start a VPP shell using vppctl
+---------------------------------------------------------------
+You can also use vppctl to launch a vpp shell with which you can run multiple vpp commands interactively by running:
+
+.. code-block:: console
+
+ sudo vppctl -s /run/vpp/cli-${name}.sock
+
+which will give you a command prompt.
+
+Try doing show ver that way:
+
+.. code-block:: console
+
+ sudo vppctl -s /run/vpp/cli-vpp1.sock
+ vpp# show ver
+
+Output:
+
+.. code-block:: console
+
+ vpp v17.04-rc0~177-g006eb47 built by ubuntu on fdio-ubuntu1604-sevt at Mon Jan 30 18:30:12 UTC 2017
+
+ vpp#
+
+To exit the vppctl shell:
+
+.. code-block:: console
+
+ vpp# quit
+

+
+Action: Create veth interfaces on host
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In Linux, there is a type of interface call 'veth'. Think of a 'veth'
+interface as being an interface that has two ends to it (rather than
+one).
+
+Create a veth interface with one end named **vpp1out** and the other
+named **vpp1host**
+
+::
+
+ sudo ip link add name vpp1out type veth peer name vpp1host
+
+Turn up both ends:
+
+::
+
+ sudo ip link set dev vpp1out up
+ sudo ip link set dev vpp1host up
+
+Assign an IP address
+
+::
+
+ sudo ip addr add 10.10.1.1/24 dev vpp1host
+
+Display the result:
+
+::
+
+ sudo ip addr show vpp1host
+
+Example Output:
+
+::
+
+ 10: vpp1host@vpp1out: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
+ link/ether 5e:97:e3:41:aa:b8 brd ff:ff:ff:ff:ff:ff

+ inet6 fe80::5c97:e3ff:fe41:aab8/64 scope link
+ valid_lft forever preferred_lft forever
+
+Action: Create vpp host- interface
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Create a host interface attached to **vpp1out**.
+
+::
+
+ sudo vppctl -s /run/vpp/cli-vpp1.sock create host-interface name vpp1out
+
+Output:
+
+::
+
+ host-vpp1out
+
+Confirm the interface:
+
+::
+
+ sudo vppctl -s /run/vpp/cli-vpp1.sock show hardware
+
+Example Output:
+
+::
+
+ Name Idx Link Hardware
+ host-vpp1out 1 up host-vpp1out
+ Ethernet address 02:fe:48:ec:d5:a7
+ Linux PACKET socket interface
+ local0 0 down local0
+ local
+
+Turn up the interface:
+
+::
+
+ sudo vppctl -s /run/vpp/cli-vpp1.sock set int state host-vpp1out up
+
+Confirm the interface is up:
+
+::
+
+ sudo vppctl -s /run/vpp/cli-vpp1.sock show int
+
+::
+
+ Name Idx State Counter Count
+ host-vpp1out 1 up
+ local0 0 down
+
+Assign ip address 10.10.1.2/24
+
+::
+
+ sudo vppctl -s /run/vpp/cli-vpp1.sock set int ip address host-vpp1out 10.10.1.2/24
+
+Confirm the ip address is assigned:
+
+::
+
+ sudo vppctl -s /run/vpp/cli-vpp1.sock show int addr
+
+::
+
+ host-vpp1out (up):
+ 10.10.1.2/24
+ local0 (dn):
+

+
+In the example above, there is bridge domain ID '0' already. Even though
+sometimes we might get feedback as below:
+
+::
+
+ no bridge-domains in use
+
+the bridge domain ID '0' still exists, where no operations are
+supported. For instance, if we try to add host-vpp1out and host-vpp1vpp2
+to bridge domain ID 0, we will get nothing setup.
+
+::
+
+ sudo vppctl -s /run/vpp/cli-vpp1.sock set int l2 bridge host-vpp1out 0

+ sudo vppctl -s /run/vpp/cli-vpp1.sock show bridge-domain 0 detail
+
+::
+
+ show bridge-domain: No operations on the default bridge domain are supported
+
+So we will create bridge domain 1 instead of playing with the default
+bridge domain ID 0.

+
+Action: Install vpp-plugins
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Snat is supported by a plugin, so vpp-plugins need to be installed
+
+::
+
+ sudo apt-get install vpp-plugins
+
+Action: Create vpp instance
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Create one vpp instance named vpp1.
+
+Confirm snat plugin is present:
+
+::
+
+ sudo vppctl -s /run/vpp/cli-vpp1.sock show plugins
+
+::
+
+ Plugin path is: /usr/lib/vpp_plugins
+ Plugins loaded:
+ 1.ioam_plugin.so
+ 2.ila_plugin.so
+ 3.acl_plugin.so
+ 4.flowperpkt_plugin.so
+ 5.snat_plugin.so
+ 6.libsixrd_plugin.so
+ 7.lb_plugin.so
+
+Action: Create veth interfaces
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+#. Create a veth interface with one end named vpp1outside and the other
+ named vpp1outsidehost
+#. Assign IP address 10.10.1.1/24 to vpp1outsidehost
+#. Create a veth interface with one end named vpp1inside and the other
+ named vpp1insidehost
+#. Assign IP address 10.10.2.1/24 to vpp1outsidehost
+
+Because we'd like to be able to route \*via\* our vpp instance to an
+interface on the same host, we are going to put vpp1insidehost into a
+network namespace
+
+Create a new network namespace 'inside'
+
+::
+
+ sudo ip netns add inside
+
+Move interface vpp1inside into the 'inside' namespace:
+
+::
+
+ sudo ip link set dev vpp1insidehost up netns inside
+
+Assign an ip address to vpp1insidehost
+
+::
+
+ sudo ip netns exec inside ip addr add 10.10.2.1/24 dev vpp1insidehost
+
+Create a route inside the netns:
+
+::
+
+ sudo ip netns exec inside ip route add 10.10.1.0/24 via 10.10.2.2
+
+Action: Configure vpp outside interface
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+#. Create a vpp host interface connected to vpp1outside
+#. Assign ip address 10.10.1.2/24
+#. Create a vpp host interface connected to vpp1inside
+#. Assign ip address 10.10.2.2/24
+
+Action: Configure snat
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Configure snat to use the address of host-vpp1outside
+
+::
+
+ sudo vppctl -s /run/vpp/cli-vpp1.sock snat add interface address host-vpp1outside
+
+Configure snat inside and outside interfaces
+
+::
+
+ sudo vppctl -s /run/vpp/cli-vpp1.sock set interface snat in host-vpp1inside out host-vpp1outside
+
+Action: Prepare to Observe Snat
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Observing snat in this configuration is interesting. To do so, vagrant
+ssh a second time into your VM and run:
+
+::
+
+ sudo tcpdump -s 0 -i vpp1outsidehost
+
+Also enable tracing on vpp1
+
+Action: Ping via snat
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+::
+
+ sudo ip netns exec inside ping -c 1 10.10.1.1
+
+Action: Confirm snat
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Examine the tcpdump output and vpp1 trace to confirm snat occurred.

+Performance
+===========
+
+Overview
+^^^^^^^^
+
+One of the benefits of FD.io VPP, is high performance on relatively low-power computing, this performance is based on the following features:
+
+* A high-performance user-space network stack designed for commodity hardware.
+
+ - L2, L3 and L4 features and encapsulations.
+
+* Optimized packet interfaces supporting a multitude of use cases.
+
+ - An integrated vhost-user backend for high speed VM-to-VM connectivity.
+ - An integrated memif container backend for high speed Container-to-Container connectivity.
+ - An integrated vhost based interface to punt packets to the Linux Kernel.
+
+* The same optimized code-paths run execute on the host, and inside VMs and Linux containers.
+* Leverages best-of-breed open source driver technology: `DPDK <https://www.dpdk.org/>`_.
+* Tested at scale; linear core scaling, tested with millions of flows and mac addresses.
+
+These features have been designed to take full advantage of common micro-processor optimization techniques, such as:
+
+* Reducing cache and TLS misses by processing packets in vectors.
+* Realizing `IPC <https://en.wikipedia.org/wiki/Instructions_per_cycle>`_ gains with vector instructions such as: SSE, AVX and NEON.
+* Eliminating mode switching, context switches and blocking, to always be doing useful work.
+* Cache-lined aliged buffers for cache and memory efficiency.
+
+
+Packet Throughput Graphs

+
+ Extensible and modular graph node architecture.
+
+At runtime, the FD.io VPP platform assembles a vector of packets from RX rings,
+typically up to 256 packets in a single vector. The packet processing graph is
+then applied, node by node (including plugins) to the entire packet vector. The
+received packets typically traverse the packet processing graph nodes in the
+vector, when the network processing represented by each graph node is applied to
+each packet in turn. Graph nodes are small and modular, and loosely
+coupled. This makes it easy to introduce new graph nodes and rewire existing
+graph nodes.
+
+Plugins are `shared libraries <https://en.wikipedia.org/wiki/Library_(computing)>`_
+and are loaded at runtime by VPP. VPP find plugins by searching the plugin path
+for libraries, and then dynamically loads each one in turn on startup.
+A plugin can introduce new graph nodes or rearrange the packet processing graph.
+You can build a plugin completely independently of the FD.io VPP source tree,
+which means you can treat it as an independent component.

+=========================================
+
+FD.io's Vector Packet Processing (VPP) technology is a :ref:`fast`,
+:ref:`packet-processing` stack that runs on commodity CPUs. It provides
+out-of-the-box production quality switch/router functionality and much, much
+more. FD.io VPP is at the same time, an :ref:`extensible` and
+:ref:`developer-friendly` framework, capable of boot-strapping the development
+of packet-processing applications. The benefits of FD.io VPP are its high
+performance, proven technology, its modularity and flexibility, integrations and

+
+=================================
+What is vector packet processing?
+=================================
+
+FD.io VPP is developed using vector packet processing concepts, as opposed to
+scalar packet processing, these concepts are explained in the following sections.
+
+Vector packet processing is a common approach among high performance `Userspace
+<https://en.wikipedia.org/wiki/User_space>`_ packet processing applications such
+as developed with FD.io VPP and `DPDK
+<https://en.wikipedia.org/wiki/Data_Plane_Development_Kit>`_. The scalar based
+aproach tends to be favoured by Operating System `Kernel
+<https://en.wikipedia.org/wiki/Kernel_(operating_system)>`_ Network Stacks and
+Userspace stacks that don't have strict performance requirements.
+
+**Scalar Packet Processing**
+
+A scalar packet processing network stack typically processes one packet at a
+time: an interrupt handling function takes a single packet from a Network
+Inteface, and processes it through a set of functions: fooA calls fooB calls
+fooC and so on.
+
+.. code-block:: none
+
+ +---> fooA(packet1) +---> fooB(packet1) +---> fooC(packet1)
+ +---> fooA(packet2) +---> fooB(packet2) +---> fooC(packet2)
+ ...
+ +---> fooA(packet3) +---> fooB(packet3) +---> fooC(packet3)
+
+
+Scalar packet processing is simple, but inefficent in these ways:
+
+* When the code path length exceeds the size of the Microprocessor's instruction
+ cache (I-cache), `thrashing
+ <https://en.wikipedia.org/wiki/Thrashing_(computer_science)>`_ occurs as the
+ Microprocessor is continually loading new instructions. In this model, each
+ packet incurs an identical set of I-cache misses.
+* The associated deep call stack will also add load-store-unit pressure as
+ stack-locals fall out of the Microprocessor's Layer 1 Data Cache (D-cache).
+
+**Vector Packet Processing**
+
+In contrast, a vector packet processing network stack processes multiple packets
+at a time, called 'vectors of packets' or simply a 'vector'. An interrupt
+handling function takes the vector of packets from a Network Inteface, and
+processes the vector through a set of functions: fooA calls fooB calls fooC and
+so on.
+
+.. code-block:: none
+
+ +---> fooA([packet1, +---> fooB([packet1, +---> fooC([packet1, +--->
+ packet2, packet2, packet2,
+ ... ... ...
+ packet256]) packet256]) packet256])
+
+This approach fixes:
+
+* The I-cache thrashing problem described above, by ammoritizing the cost of
+ I-cache loads across multiple packets.
+
+* The ineffeciences associated with the deep call stack by recieving vectors
+ of up to 256 packets at a time from the Network Interface, and processes them
+ using a directed graph of node. The graph scheduler invokes one node dispatch
+ function at a time, restricting stack depth to a few stack frames.
+
+The further optimizations that this approaches enables are pipelining and
+prefetching to minimize read latency on table data and parallelize packet loads
+needed to process packets.

+.. _subinterfacecommands:
+
+.. toctree::
+
+Create Sub-Interfaces
+=====================
+This command is used to add VLAN IDs to interfaces, also known as
+subinterfaces. The primary input to this command is the '*interface*'
+and '*subId*' (subinterface Id) parameters. If no additional VLAN ID is
+provide, the VLAN ID is assumed to be the '*subId*'. The VLAN ID and
+'*subId*' can be different, but this is not recommended.
+
+This command has several variations:
+
+- **create sub-interfaces <interface> <subId>** - Create a subinterface
+ to process packets with a given 802.1q VLAN ID (same value as the
+ '*subId*').
+- **create sub-interfaces <interface> <subId> default** - Adding the
+ '*default*' parameter indicates that packets with VLAN IDs that do
+ not match any other subinterfaces should be sent to this
+ subinterface.
+- **create sub-interfaces <interface> <subId> untagged** - Adding the
+ '*untagged*' parameter indicates that packets no VLAN IDs should be
+ sent to this subinterface.
+- **create sub-interfaces <interface> <subId>-<subId>** - Create a
+ range of subinterfaces to handle a range of VLAN IDs.
+- **create sub-interfaces <interface> <subId> dot1q|dot1ad <vlanId>|any
+ [exact-match]** - Use this command to specify the outer VLAN ID, to
+ either be explicited or to make the VLAN ID different from the
+ '*subId*'.
+- **create sub-interfaces <interface> <subId> dot1q|dot1ad <vlanId>|any
+ inner-dot1q <vlanId>|any [exact-match]** - Use this command to
+ specify the outer VLAN ID and the innner VLAN ID.
+
+When '*dot1q*' or '*dot1ad*' is explictly entered, subinterfaces can be
+configured as either exact-match or non-exact match. Non-exact match is
+the CLI default. If '*exact-match*' is specified, packets must have the
+same number of VLAN tags as the configuration. For non-exact-match,
+packets must at least that number of tags. L3 (routed) interfaces must
+be configured as exact-match. L2 interfaces are typically configured as
+non-exact-match. If '*dot1q*' or '*dot1ad*' is NOT entered, then the
+default behavior is exact-match.
+
+Use the '*show interface*' command to display all subinterfaces.
+
+Summary/Usage
+-------------
+
+.. code-block:: shell
+
+ create sub-interfaces <interface> {<subId> [default|untagged]} | {<subId>-<subId>} | {<subId> dot1q|dot1ad <vlanId>|any [inner-dot1q <vlanId>|any] [exact-match]}.
+
+Examples
+--------
+
+Example of how to create a VLAN subinterface 11 to process packets on 802.1q VLAN ID 11:
+
+.. code-block:: console
+
+ vpp# create sub-interfaces GigabitEthernet2/0/0 11
+
+The previous example is shorthand and is equivalent to:
+
+.. code-block:: console
+
+ vpp# create sub-interfaces GigabitEthernet2/0/0 11 dot1q 11 exact-match
+
+Example of how to create a subinterface number that is different from the VLAN ID:
+
+.. code-block:: console
+
+ vpp# create sub-interfaces GigabitEthernet2/0/0 11 dot1q 100
+
+Examples of how to create q-in-q and q-in-any subinterfaces:
+
+.. code-block:: console
+
+ vpp# create sub-interfaces GigabitEthernet2/0/0 11 dot1q 100 inner-dot1q 200
+ vpp# create sub-interfaces GigabitEthernet2/0/0 12 dot1q 100 inner-dot1q any
+
+Examples of how to create dot1ad interfaces:
+
+.. code-block:: console
+
+ vpp# create sub-interfaces GigabitEthernet2/0/0 11 dot1ad 11
+ vpp# create sub-interfaces GigabitEthernet2/0/0 12 dot1ad 100 inner-dot1q 200
+
+Examples of '*exact-match*' versus non-exact match. A packet with outer VLAN 100 and inner VLAN 200 would match this interface, because the default is non-exact match:
+
+.. code-block:: console
+
+ vpp# create sub-interfaces GigabitEthernet2/0/0 5 dot1q 100
+
+However, the same packet would NOT match this interface because '*exact-match*' is specified and only one VLAN is configured, but packet contains two VLANs:
+
+.. code-block:: console
+
+ vpp# create sub-interfaces GigabitEthernet2/0/0 5 dot1q 100 exact-match
+
+Example of how to created a subinterface to process untagged packets:
+
+.. code-block:: console
+
+ vpp# create sub-interfaces GigabitEthernet2/0/0 5 untagged
+
+Example of how to created a subinterface to process any packet with a VLAN ID that does not match any other subinterface:
+
+.. code-block:: console
+
+ vpp# create sub-interfaces GigabitEthernet2/0/0 7 default
+
+When subinterfaces are created, they are in the down state. Example of how to enable a newly created subinterface:
+
+.. code-block:: console
+
+ vpp# set interface GigabitEthernet2/0/0.7 up

+
+Create Vhost-User
+=================
+
+Create a vHost User interface. Once created, a new virtual interface
+will exist with the name '*VirtualEthernet0/0/x*', where '*x*' is the
+next free index.
+
+There are several parameters associated with a vHost interface:
+
+- **socket <socket-filename>** - Name of the linux socket used by
+ hypervisor and VPP to manage the vHost interface. If in '*server*'
+ mode, VPP will create the socket if it does not already exist. If in
+ '*client*' mode, hypervisor will create the socket if it does not
+ already exist. The VPP code is indifferent to the file location.
+ However, if SELinux is enabled, then the socket needs to be created
+ in '*/var/run/vpp/*'.
+- **server** - Optional flag to indicate that VPP should be the server
+ for the linux socket. If not provided, VPP will be the client. In
+ '*server*' mode, the VM can be reset without tearing down the vHost
+ Interface. In '*client*' mode, VPP can be reset without bringing down
+ the VM and tearing down the vHost Interface.
+- **feature-mask <hex>** - Optional virtio/vhost feature set negotiated
+ at startup. **This is intended for degugging only.** It is
+ recommended that this parameter not be used except by experienced
+ users. By default, all supported features will be advertised.
+ Otherwise, provide the set of features desired.
+
+ - 0x000008000 (15) - VIRTIO_NET_F_MRG_RXBUF
+ - 0x000020000 (17) - VIRTIO_NET_F_CTRL_VQ
+ - 0x000200000 (21) - VIRTIO_NET_F_GUEST_ANNOUNCE
+ - 0x000400000 (22) - VIRTIO_NET_F_MQ
+ - 0x004000000 (26) - VHOST_F_LOG_ALL
+ - 0x008000000 (27) - VIRTIO_F_ANY_LAYOUT
+ - 0x010000000 (28) - VIRTIO_F_INDIRECT_DESC
+ - 0x040000000 (30) - VHOST_USER_F_PROTOCOL_FEATURES
+ - 0x100000000 (32) - VIRTIO_F_VERSION_1
+
+- **hwaddr <mac-addr>** - Optional ethernet address, can be in either
+ X:X:X:X:X:X unix or X.X.X cisco format.
+- **renumber <dev_instance>** - Optional parameter which allows the
+ instance in the name to be specified. If instance already exists,
+ name will be used anyway and multiple instances will have the same
+ name. Use with caution.
+
+
+Summary/Usage
+-------------
+
+.. code-block:: shell
+
+ create vhost-user socket <socket-filename> [server] [feature-mask <hex>] [hwaddr <mac-addr>] [renumber <dev_instance>]
+
+
+Examples
+--------
+
+ Example of how to create a vhost interface with VPP as the client
+ and all features enabled:
+
+.. code-block:: console
+
+ vpp# create vhost-user socket /var/run/vpp/vhost1.sock
+ VirtualEthernet0/0/0
+
+Example of how to create a vhost interface with VPP as the server
+and with just multiple queues enabled:
+
+.. code-block:: console
+
+ vpp# create vhost-user socket /var/run/vpp/vhost2.sock server feature-mask 0x40400000
+ VirtualEthernet0/0/1
+
+Once the vHost interface is created, enable the interface using:
+
+.. code-block:: console
+
+ vpp# set interface state VirtualEthernet0/0/0 up
+
+.. _showvhost:
+
+Show Vhost-User
+===============
+
+Display the attributes of a single vHost User interface (provide
+interface name), multiple vHost User interfaces (provide a list of
+interface names seperated by spaces) or all Vhost User interfaces (omit
+an interface name to display all vHost interfaces).

+
+ Type **exit** in the command-line if you want to exit the VM.
+
+Become the root with:
+
+.. code-block:: console
+
+ $ sudo bash
+
+Now *install* VPP in the VM. Keep in mind that VPP is already built (but not yet installed) at this point based on the commands from the provisioned script *build.sh*.
+
+When you ssh into your Vagrant box you will be placed in the directory */home/vagrant*. Change directories to */vpp/build-root*, and run these commands to install VPP based on your OS and architechture:
+
+For Ubuntu systems:
+
+.. code-block:: console
+
+ # dpkg -i *.deb
+
+For CentOS systems:
+
+.. code-block:: console
+
+ # rpm -Uvh *.rpm
+
+
+Since VPP is now installed, you can start running VPP with:
+
+.. code-block:: console
+
+ # service vpp start

+Vagrantfiles
+============
+
+A `Vagrantfile <https://www.vagrantup.com/docs/vagrantfile/>`_ contains the box and provision configuration settings for your VM. The syntax of Vagrantfiles is Ruby (Ruby experience is not necessary).
+
+The command **vagrant up** creates a *Vagrant Box* based on your Vagrantfile. A Vagrant box is one of the motivations for using Vagrant - its a "development-ready box" that can be copied to other machines to recreate the same environment.
+
+It's common for people to think that a Vagrant box *is* the VM. But rather, the VM is *inside* a Vagrant box, with the box containing additional configuration options you can set, such as VM options, scripts to run on boot, etc.
+
+This `Vagrant website for boxes <https://app.vagrantup.com/boxes/search>`_ shows you how to configure a basic Vagrantfile for your specific OS and VM software.
+
+
+Box configuration
+_________________
+
+
+Looking at the :ref:`vppVagrantfile`, we can see that the default OS is Ubuntu 16.04 (since the variable *distro* equals *ubuntu1604* if there is no VPP_VAGRANT_DISTRO variable set - thus the **else** case is executed.)
+
+.. code-block:: ruby
+
+ # -*- mode: ruby -*-
+ # vi: set ft=ruby :
+
+ Vagrant.configure(2) do |config|
+
+ # Pick the right distro and bootstrap, default is ubuntu1604
+ distro = ( ENV['VPP_VAGRANT_DISTRO'] || "ubuntu1604")
+ if distro == 'centos7'
+ config.vm.box = "centos/7"
+ config.vm.box_version = "1708.01"
+ config.ssh.insert_key = false
+ elsif distro == 'opensuse'
+ config.vm.box = "opensuse/openSUSE-42.3-x86_64"
+ config.vm.box_version = "1.0.4.20170726"
+ else
+ config.vm.box = "puppetlabs/ubuntu-16.04-64-nocm"
+
+As mentioned in the previous page, you can specify which OS and VM provider you want for your Vagrant box from the `Vagrant boxes page <https://app.vagrantup.com/boxes/search>`_, and setting your ENV variable appropriately in *env.sh*.
+
+Next in the Vagrantfile, you see some *config.vm.provision* commands. As paraphrased from `Basic usage of Provisioners <https://www.vagrantup.com/docs/provisioning/basic_usage.html>`_, by default these are only run *once* - during the first boot of the box.
+
+.. code-block:: ruby
+
+ config.vm.provision :shell, :path => File.join(File.dirname(__FILE__),"update.sh")
+ config.vm.provision :shell, :path => File.join(File.dirname(__FILE__),"build.sh"), :args => "/vpp vagrant"
+
+The two lines above set the VM to run two scripts during its first bootup: an update script *update.sh* that does basic updating and installation of some useful tools, as well as *build.sh* that builds (but does **not** install) VPP in the VM. You can view these scripts on your own for more detail on the commands used.
+
+
+Looking further in the :ref:`vppVagrantfile`, you can see more Ruby variables being set to ENV's or to a default value:
+
+.. code-block:: ruby
+
+ # Define some physical ports for your VMs to be used by DPDK
+ nics = (ENV['VPP_VAGRANT_NICS'] || "2").to_i(10)
+ for i in 1..nics
+ config.vm.network "private_network", type: "dhcp"
+ end
+
+ # use http proxy if avaiable
+ if ENV['http_proxy'] && Vagrant.has_plugin?("vagrant-proxyconf")
+ config.proxy.http = ENV['http_proxy']
+ config.proxy.https = ENV['https_proxy']
+ config.proxy.no_proxy = "localhost,127.0.0.1"
+ end
+
+ vmcpu=(ENV['VPP_VAGRANT_VMCPU'] || 2)
+ vmram=(ENV['VPP_VAGRANT_VMRAM'] || 4096)
+
+
+You can see how the box or VM is configured, such as the amount of NICs (defaults to 3 NICs: 1 x NAT - host access and 2 x VPP DPDK enabled), CPUs (defaults to 2), and RAM (defaults to 4096 MB).
+
+
+Box bootup
+__________
+
+
+Once you're satisfied with your *Vagrantfile*, boot the box with:
+
+.. code-block:: console
+
+ $ vagrant up
+
+Doing this above command will take quite some time, since you are installing a VM and building VPP. Take a break and get some scooby snacks while you wait.
+
+To confirm it is up, show the status and information of Vagrant boxes with:
+
+.. code-block:: console
+
+ $ vagrant global-status
+ id name provider state directory
+ -----------------------------------------------------------------------------------------
+ d90a17b default virtualbox poweroff /home/centos/andrew-vpp/vppsb/vpp-userdemo

+ c199140 default virtualbox running /home/centos/andrew-vpp/vppsb3/vpp-userdemo
+
+ You will have only one machine running, but I have multiple as shown above.
+
+.. note::
+
+ To poweroff your VM, type:
+
+ .. code-block:: console
+
+ $ vagrant halt <id>
+
+ To resume your VM, type:
+
+ .. code-block:: console
+
+ $ vagrant resume <id>
+
+ To destroy your VM, type:
+
+ .. code-block:: console
+
+ $ vagrant destroy <id>
+
+ Note that "destroying" a VM does not erase the box, but rather destroys all resources allocated for that VM. For other Vagrant commands, such as destroying a box, refer to the `Vagrant CLI Page <https://www.vagrantup.com/docs/cli/>`_.

+Installing Vbox and Vagrant
+===========================
+
+Installing VirtualBox
+_____________________
+
+First download VirtualBox, which is virtualization software for creating VM's.
+
+If you're on CentOS, follow the `steps here <https://wiki.centos.org/HowTos/Virtualization/VirtualBox>`_.
+
+
+If you're on Ubuntu, perform:
+
+.. code-block:: console
+
+ $ sudo apt-get install virtualbox
+
+Installing Vagrant
+__________________
+
+Here we are on a 64-bit version of CentOS, downloading and installing Vagrant 2.1.2:
+
+.. code-block:: console
+
+ $ yum -y install https://releases.hashicorp.com/vagrant/2.1.2/vagrant_2.1.2_x86_64.rpm
+
+This is a similar command, but on a 64-bit version of Debian:
+
+.. code-block:: console
+
+ $ sudo apt-get install https://releases.hashicorp.com/vagrant/2.1.2/vagrant_2.1.2_x86_64.deb
+
+
+If you want to download a newer version of Vagrant or one specific to your OS and architecture, go to the Vagrant `download page <https://www.vagrantup.com/downloads.html>`_, right-click and copy the link address for your specified version, and replace the above install command for your respective OS and architechure.

+
+
+Setting your ENV Variables
+==========================
+
+
+The :ref:`vppVagrantfile` used in the VPP repo sets the configuration options based on your ENV (environment) variables, or to default the configuration at specified values if your ENV variables are not initialized (if you did not run the *env.sh* script found below).
+
+This is the *env.sh* script found in *vpp/extras/vagrant*. When run, the script sets ENV variables using the **export** command.
+
+.. code-block:: bash
+
+ export VPP_VAGRANT_DISTRO="ubuntu1604"
+ export VPP_VAGRANT_NICS=2
+ export VPP_VAGRANT_VMCPU=4
+ export VPP_VAGRANT_VMRAM=4096
+
+In the :ref:`vppVagrantfile`, you can see these same ENV variables used (discussed on the next page).
+
+Adding your own ENV variables is easy. For example, if you wanted to setup proxies for your VM, you would add to this file the **export** commands found in the :ref:`building VPP commands section <building>`. Note that this only works if the ENV variable is defined in the :ref:`vppVagrantfile`.
+
+Once you're finished with *env.sh* script, and you are in the directory containing *env.sh*, run the script to set the ENV variables with:
+
+.. code-block:: console
+
+ $ source ./env.sh

+
+There are various commands and tools that can help users see FD.io VPP CPU and memory usage at runtime.
+
+Linux top/htop
+==============
+
+The Linux top and htop are decent tools to look at FD.io VPP cpu and memory usage, but they will only show
+preallocated memory and total CPU usage. These commands can be useful to show which cores VPP is running on.
+
+This is an example of VPP instance that is running on cores 8 and 9. For this output type **top** and then
+type **1** when the tool starts.

+
+VPP CPU Load
+============
+
+To find the VPP CPU load or how busy VPP is use the **show runtime** command.
+
+With at least one interface in polling mode, the VPP CPU utilization is always 100%.
+
+A good indicator of CPU load is **"average vectors/node"**. A bigger number means VPP
+is more busy but also more efficient. The Maximum value is 255 (unless you change VLIB_FRAME_SIZE in code).
+It basically means how many packets are processed in batch.
+
+If VPP is not loaded it will likely poll so fast that it will just get one or few
+packets from the rx queue. This is the case shown below on Thread 1. As load goes up vpp
+will have more work to do, so it will poll less frequently, and that will result in more
+packets waiting in rx queue. More packets will result in more efficient execution of the
+code so number of clock cycles / packet will go down. When "average vectors/node" goes up
+close to 255, you will likely start observing rx queue tail drops.

+Reporting Bugs
+==============
+
+Although every situation is different, this page describes how to
+collect data which will help make efficient use of everyone's time
+when dealing with vpp bugs.
+
+Before you press the Jira button to create a bug report - or email
+vpp-dev@lists.fd.io - please ask yourself whether there's enough
+information for someone else to understand and possibly to reproduce
+the issue given a reasonable amount of effort. **Unicast emails to
+maintainers, committers, and the project PTL are strongly discouraged.**
+
+A good strategy for clear-cut bugs: file a detailed Jira ticket, and
+then send a short description of the issue to vpp-dev@lists.fd.io,
+perhaps from the Jira ticket description. It's fine to send email to
+vpp-dev@lists.fd.io to ask a few questions **before** filing Jira tickets.
+
+Data to include in bug reports
+==============================
+
+Image version and operating environment
+---------------------------------------
+
+Please make sure to include the vpp image version and command-line arguments.
+
+.. code-block:: console
+
+ $ sudo bash
+ # vppctl show version verbose cmdline
+ Version: v18.07-rc0~509-gb9124828
+ Compiled by: vppuser
+ Compile host: vppbuild
+ Compile date: Fri Jul 13 09:05:37 EDT 2018
+ Compile location: /scratch/vpp-showversion
+ Compiler: GCC 7.3.0
+ Current PID: 5211
+ Command line arguments:
+ /scratch/vpp-showversion/build-root/install-vpp_debug-native/vpp/bin/vpp
+ unix
+ interactive
+
+With respect to the operating environment: if misbehavior involving a
+specific VM / container / bare-metal environment is involved, please
+describe the environment in detail:
+
+* Linux Distro (e.g. Ubuntu 14.04.3 LTS, CentOS-7, etc.)
+* NIC type(s) (ixgbe, i40e, enic, etc. etc.), vhost-user, tuntap
+* NUMA configuration if applicable
+
+Please note the CPU architecture (x86_86, aarch64), and hardware platform.
+
+When practicable, please report issues against released software, or
+unmodified master/latest software.
+
+"Show" command output
+---------------------
+
+Every situation is different. If the issue involves a sequence of debug CLI command, please enable CLI command logging, and send the sequence involved. Note that the debug CLI is a developer's tool - **no warranty express or implied** - and that we may choose not to fix debug CLI bugs.
+
+Please include "show error" [error counter] output. It's often helpful to "clear error", send a bit of traffic, then "show error" particularly when running vpp on a noisy networks.
+
+Please include ip4 / ip6 / mpls FIB contents ("show ip fib", "show ip6 fib", "show mpls fib", "show mpls tunnel").
+
+Please include "show hardware", "show interface", and "show interface address" output
+
+Here is a consolidated set of commands that are generally useful before/after sending traffic. Before sending traffic.
+
+.. code-block:: console
+
+ vppctl clear hardware
+ vppctl clear interface
+ vppctl clear error
+ vppctl clear run
+
+Send some traffic and then issue the following commands.
+
+.. code-block:: console
+
+ vppctl show version verbose
+ vppctl show hardware
+ vppctl show hardware address
+ vppctl show interface
+ vppctl show run
+ vppctl show error
+
+Here are some protocol specific show commands that may also make
+sense. Only include those features which have been configured.
+
+.. code-block:: console
+
+ vppctl show l2fib
+ vppctl show bridge-domain
+
+ vppctl show ip fib
+ vppctl show ip arp
+
+ vppctl show ip6 fib
+ vppctl show ip6 neighbors
+
+ vppctl show mpls fib
+ vppctl show mpls tunnel
+
+Network Topology
+----------------
+
+Please include a crisp description of the network topology, including
+L2 / IP / MPLS / segment-routing addressing details. If you expect
+folks to reproduce and debug issues, this is a must.
+
+At or above a certain level of topological complexity, it becomes
+problematic to reproduce the original setup.
+
+Packet Tracer Output
+--------------------
+
+If you capture packet tracer output which seems relevant, please include it.
+
+.. code-block:: console
+
+ vppctl trace add dpdk-input 100 # or similar
+
+send-traffic
+
+.. code-block:: console
+
+ vppctl show trace
+
+Capturing post-mortem data
+==========================
+
+It should go without saying, but anyhow: **please put post-mortem data
+in obvious, accessible places.** Time wasted trying to acquire
+accounts, credentials, and IP addresses simply delays problem
+resolution.
+
+Please remember to add post-mortem data location information to Jira
+tickets.
+
+Syslog Output
+-------------
+
+The vpp signal handler typically writes a certain amount of data in
+/var/log/syslog before exiting. Make sure to check for evidence, e.g
+via "grep /usr/bin/vpp /var/log/syslog" or similar.
+
+Binary API Trace
+----------------
+
+If the issue involves a sequence of control-plane API messages - even
+a very long sequence - please enable control-plane API
+tracing. Control-plane API post-mortem traces end up in
+/tmp/api_post_mortem.<pid>.
+
+Please remember to put post-mortem binary api traces in accessible
+places.
+
+These API traces are especially helpful in cases where the vpp engine
+is throwing traffic on the floor, e.g. for want of a default route or
+similar.
+
+Make sure to leave the default stanza "... api-trace { on } ... " in
+the vpp startup configuration file /etc/vpp/startup.conf, or to
+include it in the command line arguments passed by orchestration
+software.
+
+Core Files
+----------
+
+Production systems, as well as long-running pre-production soak-test
+systems, **must** arrange to collect core images. There are various
+ways to configure core image capture, including e.g. the Ubuntu
+"corekeeper" package. In a pinch, the following very basic sequence
+will capture usable vpp core files in /tmp/dumps.
+
+.. code-block:: console
+
+ # mkdir -p /tmp/dumps
+ # sysctl -w debug.exception-trace=1
+ # sysctl -w kernel.core_pattern="/tmp/dumps/%e-%t"
+ # ulimit -c unlimited
+ # echo 2 > /proc/sys/fs/suid_dumpable
+
+Vpp core files often appear enormous. Gzip typically compresses them
+to manageable sizes. A multi-GByte corefile often compresses to 10-20
+Mbytes.
+
+Please remember to put compressed core files in accessible places.
+
+Make sure to leave the default stanza "... unix { ... full-coredump
+... } ... " in the vpp startup configuration file
+/etc/vpp/startup.conf, or to include it in the command line arguments
+passed by orchestration software.
+
+Core files from private, modified images are discouraged. If it's
+necessary to go that route, please copy the **exact** Debian
+packages (or RPMs) corresponding to the core file to the same public
+place as the core file. In particular.
+
+* vpp_<version>_<arch>.deb # the vpp executable
+* vpp-dbg_<version>_<arch>.deb # debug symbols
+* vpp-dev_<version>_<arch>.deb # development package
+* vpp-lib_<version>_<arch>.deb # shared libraries
+* vpp-plugins_<version>_<arch>.deb # plugins
+
+Please include the full commit-ID the Jira ticket.
+
+If we go through the setup process only to discover that the image and
+core files don't match, it will simply delay resolution of the
+issue. And it will annoy the heck out of the engineer who just wasted
+their time. Exact means **exact**, not "oh, gee, I added a few lines
+of debug scaffolding since then..."

Keep note of this network interface name for the veth connected to *cone* (ex. vethQL7KOC), and the other network interface name for *ctwo*.
+
+With VPP in the host machine, show current VPP interfaces:

+
+ root@localhost:~# vppctl show inter
+ Name Idx State MTU (L3/IP4/IP6/MPLS) Counter Count
+ local0 0 down 0/0/0/0
+
+Which should only output local0.
+
+Based on the names of the network interfaces discussed previously, which are specific to my systems, we can create VPP host-interfaces:
+
+.. code-block:: console
+
+ root@localhost:~# vppctl create host-interface name vethQL7K0C
+ root@localhost:~# vppctl create host-interface name veth8NA72P
+
+Verify they have been set up properly:
+
+.. code-block:: console
+
+ root@localhost:~# vppctl show inter
+ Name Idx State MTU (L3/IP4/IP6/MPLS) Counter Count
+ host-vethQL7K0C 1 down 9000/0/0/0
+ host-veth8NA72P 2 down 9000/0/0/0
+ local0 0 down 0/0/0/0
+
+Which should output *three network interfaces*, local0, and the other two host network interfaces linked to the container veth's.
+
+
+Set their state to up:
+
+.. code-block:: console
+
+ root@localhost:~# vppctl set interface state host-vethQL7K0C up
+ root@localhost:~# vppctl set interface state host-veth8NA72P up
+
+Verify they are now up:
+
+.. code-block:: console
+
+ root@localhost:~# vppctl show inter
+ Name Idx State MTU (L3/IP4/IP6/MPLS) Counter Count
+ host-vethQL7K0C 1 up 9000/0/0/0
+ host-veth8NA72P 2 up 9000/0/0/0
+ local0 0 down 0/0/0/0
+
+
+Add IP addresses for the other end of each veth link:
+
+.. code-block:: console
+
+ root@localhost:~# vppctl set interface ip address host-vethQL7K0C 172.16.1.1/24
+ root@localhost:~# vppctl set interface ip address host-veth8NA72P 172.16.2.1/24
+
+
+Verify the addresses are set properly by looking at the L3 table:
+
+.. code-block:: console
+
+ root@localhost:~# vppctl show inter addr
+ host-vethQL7K0C (up):
+ L3 172.16.1.1/24
+ host-veth8NA72P (up):
+ L3 172.16.2.1/24
+ local0 (dn):

+
+Creating Containers
+___________________
+
+First you should have root privileges:
+
+.. code-block:: console
+
+ $ sudo bash
+
+Then install packages for containers such as lxc:
+
+.. code-block:: console
+
+ # apt-get install bridge-utils lxc
+
+As quoted from the `lxc.conf manpage <https://linuxcontainers.org/it/lxc/manpages/man5/lxc.conf.5.html>`_, "container configuration is held in the config stored in the container's directory.
+A basic configuration is generated at container creation time with the default's recommended for the chosen template as well as extra default keys coming from the default.conf file."
+
+"That *default.conf* file is either located at /etc/lxc/default.conf or for unprivileged containers at ~/.config/lxc/default.conf."
+
+Since we want to ping between two containers, we'll need to **add to this file**.
+
+Look at the contents of *default.conf*, which should initially look like this:
+
+.. code-block:: console
+
+ # cat /etc/lxc/default.conf
+ lxc.network.type = veth
+ lxc.network.link = lxcbr0
+ lxc.network.flags = up
+ lxc.network.hwaddr = 00:16:3e:xx:xx:xx
+
+As you can see, by default there is one veth interface.
+
+Now you will *append to this file* so that each container you create will have an interface for a Linux bridge and an unconsumed second interface.
+
+You can do this by piping *echo* output into *tee*, where each line is separated with a newline character *\\n* as shown below. Alternatively, you can manually add to this file with a text editor such as **vi**, but make sure you have root privileges.
+
+.. code-block:: console
+
+ # echo -e "lxc.network.name = veth0\nlxc.network.type = veth\nlxc.network.name = veth_link1" | sudo tee -a /etc/lxc/default.conf
+
+Inspect the contents again to verify the file was indeed modified:
+
+.. code-block:: console
+
+ # cat /etc/lxc/default.conf
+ lxc.network.type = veth
+ lxc.network.link = lxcbr0
+ lxc.network.flags = up
+ lxc.network.hwaddr = 00:16:3e:xx:xx:xx
+ lxc.network.name = veth0
+ lxc.network.type = veth
+ lxc.network.name = veth_link1
+
+
+After this, we're ready to create the containers.
+
+Creates an Ubuntu Xenial container named "cone".
+
+.. code-block:: console
+
+ # lxc-create -t download -n cone -- --dist ubuntu --release xenial --arch amd64 --keyserver hkp://p80.pool.sks-keyservers.net:80
+
+
+If successful, you'll get an output similar to this:
+
+.. code-block:: console
+
+ You just created an Ubuntu xenial amd64 (20180625_07:42) container.
+
+ To enable SSH, run: apt install openssh-server
+ No default root or user password are set by LXC.
+
+
+Make another container "ctwo".
+
+.. code-block:: console
+
+ # lxc-create -t download -n ctwo -- --dist ubuntu --release xenial --arch amd64 --keyserver hkp://p80.pool.sks-keyservers.net:80
+
+
+List your containers to verify they exist:
+
+
+.. code-block:: console
+
+ # lxc-ls
+ cone ctwo
+
+
+Start the first container:
+
+.. code-block:: console
+
+ # lxc-start --name cone
+
+And verify its running:
+
+.. code-block:: console
+
+ # lxc-ls --fancy
+ NAME STATE AUTOSTART GROUPS IPV4 IPV6
+ cone RUNNING 0 - - -
+ ctwo STOPPED 0 - - -
+
+
+.. note::
+
+ Here are some `lxc container commands <https://help.ubuntu.com/lts/serverguide/lxc.html.en-GB#lxc-basic-usage>`_ you may find useful:
+
+
+ .. code-block:: console
+
+ sudo lxc-ls --fancy
+ sudo lxc-start --name u1 --daemon
+ sudo lxc-info --name u1
+ sudo lxc-stop --name u1

+
+To enter our container via the shell, type:
+
+.. code-block:: console
+
+ # lxc-attach -n cone

+Using VPP as a Home Gateway
+===========================
+
+Vpp running on a small system (with appropriate NICs) makes a fine
+home gateway. The resulting system performs far in excess of
+requirements: a TAG=vpp_debug image runs at a vector size of ~1.1
+terminating a 90-mbit down / 10-mbit up cable modem connection.
+
+At a minimum, install sshd and the isc-dhcp-server. If you prefer, you

+Using the temporal mac filter plugin
+------------------------------------
+
+If you need to restrict network access for certain devices to specific

+
+ bin mactime_enable_disable GigabitEthernet0/14/0
+ bin mactime_enable_disable GigabitEthernet0/14/1
+ ...
+
+Create the required src-mac-address rule database. There are 4 rule

+
+* allow-static - pass traffic from this mac address
+* drop-static - drop traffic from this mac address
+* allow-range - pass traffic from this mac address at specific times
+* drop-range - drop traffic from this mac address at specific times

+FD.io VPP as a vSwitch/vRouter
+------------------------------
+
+.. note::
+
+ We need to provide commands and and show how to use VPP as a vSwitch/vRouter
+
+One of the use cases for the FD.io VPP platform is to implement it as a
+virtual switch or router. The following section describes examples of
+possible implementations that can be created with the FD.io VPP platform. For
+more in depth descriptions about other possible use cases, see the list
+of

+
+ Figure: Linux host as a vSwitch
+
+You can use the FD.io VPP platform to create out-of-the-box virtual switches
+(vSwitch) and virtual routers (vRouter). The FD.io VPP platform allows you to
+manage certain functions and configurations of these application through
+a command-line interface (CLI).
+
+Some of the functionality that a switching application can create
+includes:
+
+* Bridge Domains
+* Ports (including tunnel ports)
+* Connect ports to bridge domains
+* Program ARP termination
+
+Some of the functionality that a routing application can create
+includes:
+
+* Virtual Routing and Forwarding (VRF) tables (in the thousands)
+* Routes (in the millions)

+Prerequisites
+-------------
+
+For this use case we will assume FD.io VPP is installed. We will also assume the user can create and start
+basic virtual machines. This use case will use the linux virsh commands. For more information on virsh
+refer to `virsh man page <https://linux.die.net/man/1/virsh>`_.
+
+The image that we use is based on an Ubuntu cloud image downloaded from:
+`Ubuntu Cloud Images <https://cloud-images.ubuntu.com/xenial/current>`_.
+
+All FD.io VPP commands are being run from a su shell.
+
+.. _vhosttopo:
+
+Topology
+---------
+
+In this case we will use 2 systems. One system we will be running standard linux, the other will
+be running FD.io VPP.
+

+ Vhost Use Case Topology
+
+Creating The Virtual Interface
+------------------------------
+
+We will start on the system running FD.io VPP and show that no Virtual interfaces have been created.
+We do this using the :ref:`showintcommand` command.
+
+Notice we do not have any virtual interfaces. We do have an interface (TenGigabitEthernet86/0/0) that
+is up. This interface is connected to a system running, in our example standard linux. We will use
+this system to verify our connectivity to our VM with ping.

+
+For more information on the interface commands refer to: :ref:`intcommands`
+
+The next step will be to create the virtual port using the :ref:`createvhostuser` command.
+This command will create the virtual port in VPP and create a linux socket that the VM will
+use to connect to VPP.
+
+The port can be created using VPP as the socket server or client.
+
+Creating the VPP port:
+
+.. code-block:: console
+
+ vpp# create vhost socket /tmp/vm00.sock
+ VirtualEthernet0/0/0
+ vpp# show int
+ Name Idx State Counter Count
+ TenGigabitEthernet86/0/0 1 up
+ TenGigabitEthernet86/0/1 2 down
+ VirtualEthernet0/0/0 3 down
+ local0 0 down
+ vpp#
+
+Notice the interface **VirtualEthernet0/0/0**. In this example we created the virtual interface as
+a client.
+

+Creating the Virtual Machine
+----------------------------
+
+We will now create the virtual machine. We use the "virsh create command". For the complete file we
+use refer to :ref:`xmlexample`.
+
+It is important to note that in the XML file we specify the socket path that is used to connect to
+FD.io VPP.
+
+This is done with a section that looks like this
+
+.. code-block:: console
+
+ <interface type='vhostuser'>
+ <mac address='52:54:00:4c:47:f2'/>
+ <source type='unix' path='/tmp//vm00.sock' mode='server'/>

+ </interface>
+
+Notice the **interface type** and the **path** to the socket.
+
+Now we create the VM. The virsh list command shows the VMs that have been created. We start with no VMs.
+
+.. code-block:: console
+
+ $ virsh list
+ Id Name State
+ ----------------------------------------------------
+
+Create the VM with the virsh create command specifying our xml file.
+
+.. code-block:: console
+
+ $ virsh create ./iperf3-vm.xml
+ Domain iperf-server3 created from ./iperf3-vm.xml
+
+ $ virsh list
+ Id Name State
+ ----------------------------------------------------
+ 65 iperf-server3 running
+
+The VM is now created.
+
+.. note::
+
+ After a VM is created an xml file can created with "virsh dumpxml".
+
+.. code-block:: console
+
+ $ virsh dumpxml iperf-server3
+ <domain type='kvm' id='65'>
+ <name>iperf-server3</name>

+ <memory unit='KiB'>262144</memory>
+ .....
+
+Once the virtual machine is created notice the socket filename shows **Success** and
+there are **Memory Regions**. At this point the VM and FD.io VPP are connected. Also
+notice **qsz 256**. This system is running an older version of qemu. A queue size of 256
+will affect vhost throughput. The qsz should be 1024. On the web you should be able to
+find ways to install a newer version of qemu or change the queue size.

+Bring the Interfaces Up
+-----------------------
+
+We can now bring all the pertinent interfaces up. We can then we will then be able to communicate
+with the VM from the remote system running Linux.
+
+Bring the interfaces up with :ref:`setintstate` command.
+
+.. code-block:: console

+
+Ping from the VM
+----------------
+
+The remote Linux system has an ip address of "10.0.0.2" we can now reach it from the VM.
+
+Use the "virsh console" command to attach to the VM. "ctrl-D" to exit.
+
+.. code-block:: console
+

+Limitations
+-----------
+There are some limitations when using the qemu vhost driver. Some are described in this section.
+
+Performance
+^^^^^^^^^^^
+
+VPP performance with vHost is limited by the Qemu vHost driver. FD.io VPP 18.04 CSIT vHost testing
+shows with 2 threads, 2 cores and a Queue size of 1024 the maximum NDR throughput was about 7.5 Mpps.
+This is about the limit at this time.
+
+For all the details on the CSIT VM vhost connection refer to the
+`CSIT VM vHost performance tests <https://docs.fd.io/csit/rls1804/report/vpp_performance_tests/packet_throughput_graphs/vm_vhost.html>`_.
+
+
+Features
+^^^^^^^^
+
+These are the features not supported with FD.io VPP vHost.
+
+* VPP implements vHost in device mode only. VPP is intended to work with Qemu which implements vHost in driver mode, it does not implement vHost driver mode.
+* VPP vHost implementation does not support checksum or transmit segmentation offload.
+* VPP vHost implementation does not support packet receive filtering feature for controlling receive traffic.
