I have eight cisco 6509 switches interconected via EtherChannel's.VLAN 15 exists on each on of them and is in the allowed VLAN list on the etherchannel.
My question is that if i start a local SPAN session ( to capture VLAN 15) on say switch 1,will this session capture the VLAN 15 traffic as seen on other switches aswell.
Thanks!

Hi,
I'm pretty sure it'll just capture local VLAN 15 traffic. RSPAN is the one that captures remote VLAN traffic.

Hi,
You shall use RSPAN (Remote SPAN) for monitoring ports on other switches:

Yeah,i also think that way but the Trunk-Ports ( Etherchannel) also carry VLAN 15.Any possibility that VLAN15 traffic from inter-conected switches also make way in the SPAN session.

Yes, any VLAN 15 traffic recieved on the switch running the local SPAN session will be seen.
If some VLAN 15 traffic travelled from SW2 through SW1, it would be seen.

hi,
Yes only if this traffic reaches the local switch.
