I have 2 switches 3548 in stack and i need to monitor ALL the traffic in the 2 switches (not only the traffic going thrught the 2 devices)
I know that 3548 don't support RSPAN;
I suppose i need to define all the ports on both switches in stack as source SPAN ports. Do I need to define a VLAN for all these ports (in both switches the same ) as switch 3548 support SPAN only on port of the same VLAN?
Do I need TWO SPAN port (one for each switch) or i can use ONE SPAN destination port to monitor ALL the traffic throught and in the 2 switches?
