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?
AFAIK, you won't be able to have traffic sent back from the 3750 with rpsan. The 3750 doesn't support erspan, so you may be limited to using span/rspan locally to a server at that location. There may be other tricks that I'm not aware of, but I believe you're going to be limited to that location.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
