+To run vpp with the debug shell:
+
+sudo ~vagrant/git/vpp/build-root/install-vpp_debug-native/vpp/bin/vpe 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

+                                vpe-icmp4-oam [2]
