Hi, Not quite the answer i was hoping for, but many thanks for taking the time to confirm the situation. Guess it looks like i need to wait for a code update :( Thanks again, Rob ... View more

HI, Thanks for the reply. Below is an output from the CLI menu (within the monitor session sub menu) - as u can see there is no filter vlan option.  I cannot see anywhere else to add a filter option for an etherchannel trunk interface?  At the moment the monitor session is currently set to monitor the whole vlan123, however i want to monitor only vlan 123 on a specific etherchannel trunk interface.

Hi, The topology is simply 3 2950 switches - all interconnected (i.e each has two connections),I have just upgraded the IOS to a newer version on switch 2 - and the port id now appears in a different format which seems to make more senses (e,g 128.1 - the priority and interface number) although im not sure how this would translate when looking at ports on a modular switch? The output below is from the two 2950 switches: Switch-1#sh spanning-tree int fa0/1 Interface Fa0/1 (port 13) in Spanning tree 1 is FORWARDING Port path cost 19, Port priority 128 Designated root has priority 8192, address 0009.7cfa.3b81 Designated bridge has priority 8192, address 0009.7cfa.3b81 Designated port is 1, path cost 0 Timers: message age 2, forward delay 0, hold 0 BPDU: sent 3025, received 2266 Switch-2#sh spanning-tree int fa0/1 Port 1 (FastEthernet0/1) of VLAN1 is forwarding Port path cost 19, Port priority 128, Port Identifier 128.1.
