We are changing our 4200 from inline mode to promiscuous mode that is connected to our redunant 6509 core switches. Internally we disagree if we need to create a span on the 6509's to send the traffic to the 4200. Has anybody doen this or does anyone know how this is to be configured. Any help would be great.

we have never had it in promiscuous mode before. I think we need to do a SPAN and my co-worker disagrees. If I understand you correctly you are saying we need a SPAN...correct???

yes, or VACLs. At least, I can't think of any other way to get all the switch traffic down to a single port or couple ports. You certainly can't just plug it into a switch port in promiscuous mode and expect to see all traffic.
