RSPAN - Page 2

Hi there, I have som problem with RSPAN configuration. My topology is SW4506 where I want to mirror port to RSPAN vlan, this switch is connected via trunk port to L3 switch 4510 and from 4510 via trunk to L2 switch 2960, which is my desired RSPAN destination port gi0/2. I have created special rspan vlan by commands

conf t -> vlan 66 -> remote-span->name RSPAN. I have created this vlan on those 3 switches and distrubuted vlan 66 over trunk ports to those switches.

SW4506 is configured like this:

monitor session 1 source interface gix/x both

monitor session 1 destination remote vlan 66

sw2960:

monitor session 1 source remote vlan 66

monitor session 1 destination interface gi0/2

After this I have no mirrored traffic. Do I need to do some configuration on my L3 4510 switch?

Have you also made sure the vlan is in the vtp database of both switches and you dont have any devices physically attached to the rspan vlan
