While this isn't Cisco VoIP specific, it is Cisco specific and does involve VoIP..... :-) I need to setup a mirrored port on a 3548 to monitor the RTP streams on a vlan. I configured Fa0/7 for "port monitoring vlan 1", but all I see is CCM http/https/icmp traffic, never any RTP streams. What am i missing? Tia, -Jim P.
