Hi, when I want to use RSPAN, do I need dedicated VSAN for it ? Or VSAN 1 will do it ?
I understand that dedicated VSAN is better so there is no unnecessary traffic, but is it needed ? And if yes, where is it documented ? I didn't find it in configuration guide, but saw it in implementation redbook from IBM. Thank you
This is an interesting question. The sample configs in the configuration guide show ST and SD ports configured in VSAN 1, but the fc-tunnel is in VSAN 5. You're right - the documentation doesn't make it clear whether or not the fc-tunnel needs its own VSAN. Is there anyone at Cisco who can clear this up for us?
You do not need a dedicated VSAN to use RSPAN, and you can use any valid VSAN. The VSAN does need to be trunked among all the switches passing RSPAN traffic. I recently set up a 4-switch (3 hop) RSPAN configuration using VSAN 1700 and it worked fine. Be sure to have an IP address in the same subnet assigned to the VSAN virtual (IPFC) interface on each switch and enable IP routing and fc-tunnel on each switch.
Let me start by telling you that there is already a very nice document in the Cisco Community Forums which describes the procedure to upgrade the APIC CIMC. In case you came across this document before looking into the mentioned one, here is...
