Configuring a SET-Based Switch for RSPAN

Basic steps are the same as with IOS switches. Trunking structure is configured independently of RSPAN and has to be in place before RSPAN is configured. Basically, you need to use the same VTP domain on all switches and configure some ports as trunking-desirable. VTP negotiation will do the rest. For example, running the command:

Sw4000-1(enable) set vtp domain cisco
Sw4000-2(enable) set vtp domain cisco

on all switches, and additionally using the command

Sw4000-2> (enable) set trunk 5/1 desirable

on switch S2 will result in establishing trunking between them.

Then RSPAN VLANs are created. Using the same numbering as in previous sections, we need to configure the following on a VPT server switch:

Sw4000> (enable) set vlan 123 rspan
       Vlan 123 configuration successful
Sw4000> (enable) show vlan
VLAN   DynCreated   RSPAN
