-To run vpp with the debug shell:
-
-sudo vpp unix interactive
-
-which will result in a prompt that looks like:
-
-DBGvpd#
-
-To give it a spin, we can create a tap interface and try a simple ping
-(with trace).
-
-To create the tap:
-
-DBGvpd# tap connect foobar
-Created tap-0 for Linux tap 'foobar'
-DBGvpd# show int
-
-To assign it an ip address (and 'up' the interface):
-
-DBGvpd# set int ip address tap-0 192.168.1.1/24
-DBGvpd# set int state tap-0 up
-
-To turn on packet tracing for the tap interface:
-DBGvpd# trace add tapcli-rx 10
-
-Now, to set up and try the other end from the unix prompt:
-vagrant@vagrant-ubuntu-trusty-64:~$ sudo ip addr add 192.168.1.2/24 dev foobar
-vagrant@vagrant-ubuntu-trusty-64:~$ ping -c 3 192.168.1.1
-
-To look at the trace, back in the vpp CLI:
-DBGvpd# show trace
-
-And to stop tracing:
-
-DBGvpd# clear trace
-
-Other fun things to look at:
-
-The vlib packet processing graph:
-DBGvpd# show vlib graph
-
-which will produce output like:
-
- Name Next Previous
-ip4-icmp-input error-punt [0] ip4-local
- ip4-icmp-echo-request [1]
- vpe-icmp4-oam [2]
-
-To read this, the first column (Name) is the name of the node.
-The second column (Next) is the name of the children of that node.
-The third column (Previous) is the name of the parents of this node.
