It would appear as if a typical SPAN port does not pass the VLAN tags across that SPAN? Specifically I have a 3550 that I created a span for. The source port is the uplink fiber to the switch which is a trunk port. The only problem is that I can't seem to get any VLAN information with an analyzer that I know supports VLAN tagging. Does anyone have any experience with how to get my VLAN tags across my span session?
