I have a Cisco 3750 and I'm spanning a couple of ports to a single port where our Observer (packet capture server) is. These 2 ports I'm monitoring are in Vlan 2 and Vlan 3 but in Observer it shows no VLAn info, however I can all the other traffic data.
The Observer consultant says it has to be the switch as he has seen this all working before.
Port 1/0/48 is the destination span port and it's in no vlan:
This is the span, I have to have session 1 for our Wensense server, session 2 is what I'm on about and the 2 source ports are the inside and outside of our Cisco ASA firewall.
monitor session 1 source interface Fa1/0/3
monitor session 1 destination interface Fa1/0/6
monitor session 2 source interface Fa1/0/3 , Fa1/0/9
monitor session 2 destination interface Fa1/0/48
Any ideas as this is behond my knowledge.
