To configure RSPAN source VLANs, perform this task in privileged mode:
Task
Step 1 Configure RSPAN source VLANs. All the ports in
the source VLAN become operational source ports.
Step 2
Verify the RSPAN configuration.
This example shows how to specify VLAN 200 as a source VLAN for RSPAN VLAN 500:

To configure RSPAN destination ports, perform this task in privileged mode:
Task
Step 1
Configure RSPAN destination ports. Use this
command on each of the destination switches
participating in RSPAN.
Step 2
Verify the RSPAN configuration.
Caution If the RSPAN destination port is connected to another device and reception of incoming packets is
enabled (using the inpkts enable keywords), the RSPAN destination port receives traffic for the VLAN
to which the RSPAN destination port belongs. However, the RSPAN destination port does not participate
in spanning tree for that VLAN, so avoid creating network loops with the RSPAN destination port.
This example shows how to specify port 3/1 as the RSPAN destination port in VLAN 500:
Console> (enable) set rspan destination 3/1 500
