RSPAN - if the destination port is 'across' other switches 3560
Reading through it I saw this:
•It can participate in only one SPAN session at a time (a destination port in one SPAN session cannot be a destination port for a second SPAN session).
The destination port is an audio recorder (Eventide VoIP Gateway).
I read the above that I can't send anything from ANOTHER port to that same port at the same time.
If so, none of this will work. I can easily see traffic at the same time we need to record.
Plus, the source port on the RSPAN would be in a different VLAN than the destination port- it actually is routed, so info can get there but I'm a bit confused about needing a separate VLAN just for RSPAN...
Kind of looks like it won't work in this application- I have an alternative way to record the phones (audio forwarding to the native recorder rather than the VoIP gateway). But we would need to buy more lisences.

interface we use the VLAN tag to demultiplex the VLANs. The switch needs
to determine which MAC Address table to look in for a forwarding
decision. To do this we require the switch to do...
