How many vlans are you allowed to span to a gig interface?
Dual 6509, same vlans on each with gig trunk, I want to monitor all traffic across the vlans (with ngenius) and wasn't sure how many vlans you were allowed to span to a gig interface.
There isn't a limit to my knowledge. I've done ~10 or so on a 6509 without issue. It may be the case that you can SPAN as many VLANs as you can add to the switch.
