| Basic Trace Commands |
| ~~~~~~~~~~~~~~~~~~~~ |
| |
| Show trace buffer [max COUNT]. |
| |
| .. code-block:: console |
| |
| vpp# show trace |
| |
| |
| Clear trace buffer and free memory. |
| |
| .. code-block:: console |
| |
| vpp# clear trace |
| |
| filter trace output - include NODE COUNT | exclude NODE COUNT | none. |
| |
| .. code-block:: console |
| |
| vpp# trace filter <include NODE COUNT | exclude NODE COUNT | none> |
| |
| Skills to be Learned |
| ~~~~~~~~~~~~~~~~~~~~ |
| |
| #. Setup a 'trace' |
| #. View a 'trace' |
| #. Clear a 'trace' |
| #. Verify using ping from host |
| #. Ping from vpp |
| #. Examine Arp Table |
| #. Examine ip fib |
