RSPAN Configuration

RSPAN allows for remote traffic monitoring in the data center. Define source and destination sessions to mirror interesting traffic to a remote VLAN captured by network-analysis tools. Configure a VLAN for RSPAN on the Cisco Catalyst Blade Switch 3020 and the aggregate switch as follows:

(config)# vlan <vlanID> (config-vlan)# name <vlan name> (config-vlan)# remote-span

Create a source session as follows. This interface is the interface or VLAN that contains interesting traffic.

(config) # monitor session <session id> source vlan <VLAN IDs>

Configure the RSPAN VLAN as the target for the mirrored traffic as follows:

(config) # monitor session <session ID> destination remote vlan <remote vlan ID>
