monitoring traffic over RSPAN

[20vek]

Hello.

Does anyone tried to monitor CDP/VTP over remote span sessions? It seems to work fine using local session but I can't see CDP/VTP traffic when using remote sessions. The only BPDUs I can capture is STP. Is there any limitation for BPDUs passing over remote-span VLAN?

Thank you,

"Destination ports never participate in any spanning tree instance. Local SPAN includes BPDUs in the monitored traffic, so any BPDUs seen on the destination port are from the source port. RSPAN does not support BPDU monitoring."
