Folks,
MY question pertains to RSPAN.
At my remote branch I have a 2811 voice GW connecting to a 3560 switch. I would like to remote span the switch port to which the 2811 voice GW is connected on the switch to a vocie recording server at the headquarter. We have a point-to-point T1 connection between the remote site and HQ. First question, is this possible to remote span a port from a remote site to a HQ over T1? If yes, how (any links or configuration source would be helpful)?
My guess is that I would have to extend a vlan trunk over the T1 circuit but I am not sure how to do this.
Thanks.

Rspan is a L2 concept and hence you cannot use it
You need to use ERSPAN if you want to span over a routed network

Thanks...do you know if ERSPAN is supported on 3560 or 3750 switches? I was not able to find any documents that state this feature is supported on these switches. The only hardware i saw supporting this feature is 6500 switches w/ Sup 720.

No, it is not supported. Only supported on the Supervisor Engine 720 with PFC3B and Supervisor Engine 720 with PFC3BXL.
