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>
