MSBR2#
A debug capture is run while pinging from MSBR1 VLAN 1 to MSBR2 VLAN 1, using the
command:
debug capture data interface gigabitethernet 0/0 proto all host
180.1.1.1
While the ping command was issued in the following matter:
ping 192.168.1.1 source data source-address interface vlan 1
Note that the traffic is encrypted and therefore, only ESP packets are shown.
# debug capture data interface gigabitethernet 0/0 proto all host
