This is interesting.
sw1 and sw2 are configured for rspan. On sw1, all incoming traffic from vlan
2 is being sent to a sniffer on sw2's fa0/23.
sw2 doesn't have any ports assigned to vlan 2.
Here's the config:
SW1#f monit
monitor session 1 source vlan 2 rx
monitor session 1 destination remote vlan 10 reflector-port Fa0/7
!
sw2#f monit
monitor session 1 destination interface Fa0/23
monitor session 1 source remote vlan 10
!
end
sw2#c
Enter configuration commands, one per line. End with CNTL/Z.
sw2(config)#mon ses 1 sour vlan 2 rx
% Cannot add VLANs as source for session 1 - a RSPAN Destination session
sw2(config)#
Notice that the switch doesn't allow me to vlan 2 as another source.
Suppose sw2 had ports assigned to vlan 2. How would I configure rspan to
monitor all traffic received from vlan 2?
If sw2 had ports assigned to vlan 2, wold rspan automatically include the
traffic from those sw2 ports in vlan 2 because of the config on sw1?
TIA, Tim
