Three Cat3560 switches, I'll call them A,B, and C. We're setting up for voice recording, but are only seeing one side of the RTP stream.
On switch A:
monitor session 1 source vlan 20
monitor session 1 destination remote vlan 100
(Switch B is providing a trunk only)
monitor session 1 source remote vlan 100
monitor session 1 destination interface Gi0/18
Any help would be appreciated.
