Re: Port monitering on 3550's in stack

If yours switches in stack you can handle the two equipments as one. So you can reach the first switch port like Fastethernet 1/0/1 and the second Fastethernet 2/0/1 and after you can set the destination port to Fastethernet 1/0/4. I hope I am right, please confirm me...

monitor session "session id" source "interface"

monitor session "session id" destination "interface"

If the two device is separated you can use remote-span vlans for this issue. Create one vlan (remote-span) on your VTP server and after you can set the destination on the source device to the vlan (remote-span) and on the other switch you can set the source to the rspan vlan.

HI FCS

Thanks for your reply. The switches are 3550's so they do not act as a single switch when we stack them.

Ok, in case use Remote Span

create rspan vlan:

(config)#vlan 10

(config-vlan)#remote-span

set monitor session on source switch:

monitor session 1 source "interface"

monitor session 1 destination remote vlan 10

set monitor session on dest. switch:

monitor session 1 source remote vlan 10

monitor session 1 destination "interface"

If you don't use VTP server create on both switches RSPAN vlan.
