RSPAN only forwards broadcast traffic to destination port

Unanswered Question
Dec 21st, 2009

Hello all,

I have configured an RSPAN monitoring session on a 2950 switch. I have configured a remote-span VLAN from the VTP server switch, and checked on my monitoring source switch (VTP client in the domain) that the VLAN shows up as a remote-span VLAN.

I have configured the reflector port on the client, and the destination port and source remote-vlan on the server.

No matter what VLAN I assign to the destination port - remote-span VLAN, vlan of the monitored source-port, no VLAN id at all, I only get Broadcast and multicast traffic forwarded to my monitor (wireshark).

I've seen various discussions of this over the last coupe of years, but no definitive answe (e.g. https://supportforums.cisco.com/message/544295#147017)

Has anyone got any further thoughts?

Many thanks,
