-
-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
-
-Add Trace
-~~~~~~~~~
-
-.. code-block:: console 
-
-  vpp# trace add af-packet-input 10
