I was looking at ERSPAN to monitor VoIP traffic from a remote site (from VLAN300), the remote site has a 3750 (WS-C3750-PS-S) with one interface in routed mode that connects to the 6500 - again a routed port. The server that will be analysing the remote monitor traffic is also connected to the 6500.
Is this possible? i see that the SUP720-3B is on the list that support ERSPAN, whilst the 3750 is not. If this is not an option, how else can i monitor (presumably using RSPAN) over a routed link?
Regards
Jeff
