| * Parse subinterface names. |
| * |
| * The following subinterface syntax is supported. The first two are for |
| * backwards compatability: |
| * |
| * <intf-name> <id> |
| * - a subinterface with the name <intf-name>.<id>. The subinterface |
| * is a single dot1q vlan with vlan id <id> and exact-match semantics. |
| * |
| * <intf-name> <min_id>-<max_id> |
| * - a set of the above subinterfaces, repeating for each id |
| * in the range <min_id> to <max_id> |
| * |
| * In the following, exact-match semantics (i.e. the number of vlan tags on the |
| * packet must match the number of tags in the configuration) are used only if |
| * the keyword exact-match is present. Non-exact match is the default. |
| * |
| * <intf-name> <id> dot1q <outer_id> [exact-match] |
| * - a subinterface with the name <intf-name>.<id>. The subinterface |
| * is a single dot1q vlan with vlan id <outer_id>. |
| * |
| * <intf-name> <id> dot1q any [exact-match] |
| * - a subinterface with the name <intf-name>.<id>. The subinterface |
| * is a single dot1q vlan with any vlan id. |
| * |
| * <intf-name> <id> dot1q <outer_id> inner-dot1q <inner_id> [exact-match] |
| * - a subinterface with the name <intf-name>.<id>. The subinterface |
| * is a double dot1q vlan with outer vlan id <outer_id> and inner vlan id |
| * <inner_id>. |
| * |
| * <intf-name> <id> dot1q <outer_id> inner-dot1q any [exact-match] |
| * - a subinterface with the name <intf-name>.<id>. The subinterface |
| * is a double dot1q vlan with outer vlan id <id> and any inner vlan id. |
| * |
| * <intf-name> <id> dot1q any inner-dot1q any [exact-match] |
| * |
| * - a subinterface with the name <intf-name>.<id>. The subinterface |
| * is a double dot1q vlan with any outer vlan id and any inner vlan id. |
| * |
| * For each of the above CLI, there is a duplicate that uses the keyword |
| * "dot1ad" in place of the first "dot1q". These interfaces use ethertype |
| * 0x88ad in place of 0x8100 for the outer ethertype. Note that for double- |
| * tagged packets the inner ethertype is always 0x8100. Also note that |
| * the dot1q and dot1ad naming spaces are independent, so it is legal to |
| * have both "Gig3/0/0.1 dot1q 100" and "Gig3/0/0.2 dot1ad 100". For example: |
| * |
| * <intf-name> <id> dot1ad <outer_id> inner-dot1q <inner_id> [exact-match] |
| * - a subinterface with the name <intf-name>.<id>. The subinterface |
| * is a double dot1ad vlan with outer vlan id <outer_id> and inner vlan |
| * id <inner_id>. |
| * |
| * <intf-name> <id> untagged |
| * - a subinterface with the name <intf-name>.<id>. The subinterface |
| * has no vlan tags. Only one can be specified per interface. |
| * |
| * <intf-name> <id> default |
| * - a subinterface with the name <intf-name>.<id>. This is associated |
| * with a packet that did not match any other configured subinterface |
| * on this interface. Only one can be specified per interface. |

| * |
| * @cliexpar |

| * |
| * To create a vlan subinterface 11 to process packets on 802.1q VLAN id 11, use: |
| * |
| * vpp# create sub GigabitEthernet2/0/0 11 |
| * |
| * This shorthand is equivalent to: |
| * vpp# create sub GigabitEthernet2/0/0 11 dot1q 11 exact-match |
| * |
| * You can specify a subinterface number that is different from the vlan id: |
| * vpp# create sub GigabitEthernet2/0/0 11 dot1q 100 |
| * |
| * You can create qinq and q-in-any interfaces: |
| * vpp# create sub GigabitEthernet2/0/0 11 dot1q 100 inner-dot1q 200 |
| * vpp# create sub GigabitEthernet2/0/0 12 dot1q 100 inner-dot1q any |
| * |
| * You can also create dot1ad interfaces: |
| * vpp# create sub GigabitEthernet2/0/0 11 dot1ad 11 |
| * vpp# create sub GigabitEthernet2/0/0 12 dot1q 100 inner-dot1q 200 |
| * |
| * 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. |
| * |
| * For example, a packet with outer vlan 100 and inner 200 would match this interface: |
| * vpp# create sub GigabitEthernet2/0/0 5 dot1q 100 |
| * |
| * but would not match this interface: |
| * vpp# create sub GigabitEthernet2/0/0 5 dot1q 100 exact-match |
| * |
| * There are two special subinterfaces that can be configured. Subinterface untagged has no vlan tags: |
| * vpp# create sub GigabitEthernet2/0/0 5 untagged |
| * |
| * The subinterface default matches any packet that does not match any other subinterface: |
| * vpp# create sub GigabitEthernet2/0/0 7 default |
