Hello, I have an issue with RSPAN. It is possible to have 2 monitor source sessions each on a different switch through a single rspan vlan and one monitor destination on a third switch to a single port? All 3 switches are trunked together and transporting the rspan vlan.

Wireshark àttached on the destination port shows both tx and rx of the left most switch, but only the tx stream of the switch in the middle. See attachment. Routers are voice gateways and the traffic is in- and outbound voice to Cisco IP Phones (not in the picture)

Hello Arthur,

there have been other threads about this issue.

If I remember correctly someone was able to to do this but using C6500 switches.

Somebody else tried with other models with no success.

You can use the search feature on the top right to find more details.

Hope to help

I did have a look before I posted my message...but did not find the answer I was looking for. I am using 3750 switches.
