I'm in a situation now where I would like to use the RSPAN feature. My sniffing machine is on a 3560 switch, the machine to be sniffed is connected to a 6509. Both support RSPAN. But, between the 3560 and the 6509 there are two older switches, a 3508G-XL and a 3548XL. Both of course don't support RSPAN. We're using VTP to propagate the VLANs in the network, the 6509 is the VTP server.
What I would like to know is the following:
- Will the older switches transport the RSPAN vlan?
- Will VTP on the older propagate the fact that this is a RSPAN vlan to the 3560?
- Will this setup work at all?
We're going to replace the older stuff in some time, but it would be great if the RSPAN function could already be used now.
