I was attempting to configure an RSPAN session across two switches in the customer switch fabric today. The two switches are a model 3560 and a model 4500 respectively.
VTP is enabled on the network, so I created a VLAN 25 and named it RSPAN.
I then went to the model 3560 where I configured a "monitor session 10" to use as the RSPAN session. I configured a source port. I was then trying to configure the reflector port by using the command "mon sess 10 destination remote vlan 25 reflector-port fastEthernet0/25.
Here is what happened on the 3560:
bhiacctg(config)#mon sess 10 destination remote vlan 25 refe?
% Unrecognized command
bhiacctg(config)#mon sess 10 de?
bhiacctg(config)#mon sess 10 de ?
interface SPAN destination interface
remote SPAN destination Remote
bhiacctg(config)#mon sess 10 de remote ?
vlan Remote SPAN destination RSPAN VLAN
bhiacctg(config)#mon sess 10 de remote vlan 25 ?
Is it possible that the code on this model running does not support RSPAN? We are currently running:
