Split vlan traffic from trunk link.

Hi,

I have two switches connected by a trunk. How can I understand how many traffic is from/for a specific vlan?

Thanks.

Re: Split vlan traffic from trunk link.

Configure SPAN on a free port on one of the switches to capture all the traffic for a specific vlan.Connect a sniffer on that port and you will be able to see the traffic for that vlan.

Here is the syntax :

set span

Here is the link for more details with RSPAN aswell:
