Cisco ASR 920 series Configuration Guide Ethernet Router

Configuration Example: RSPAN Source
The following example shows how RSPAN session 2 to monitor bidirectional traffic from source interface
Gigabit Ethernet 0/0/1:
Router(config)# monitor session 2 type RSPAN-source
Router(config-mon-RSPAN-src)# source interface gigabitEthernet0/0/1 [tx |rx|both]
Router(config-mon-RSPAN-src)# destination remote VLAN 100
Router(config-mon-RSPAN-src)# no shutdown
Router(config-mon-RSPAN-src)# end
The following example shows how RSPAN session 3 to monitor bidirectional traffic from source Vlan 20:
Router(config)# monitor session 3 type RSPAN-source
Router(config-mon-RSPAN-src)# source VLAN 20 rx
Router(config-mon-RSPAN-src)# destination remote VLAN 100
Router(config-mon-RSPAN-src)# no shutdown
Router(config-mon-RSPAN-src)# end
Configuration Example: RSPAN Destination
The following example shows how to configure interface Gigabit Ethernet 0/0/1 as the destination for RSPAN
session 2:
Router(config)# monitor session 2 type RSPAN-destination
Router(config-mon-RSPAN-dst)# source remote VLAN 100
Router(config-mon-RSPAN-dst)# destination interface gigabitEthernet 0/0/1
Router(config-mon-RSPAN-dst)# end
Verifying Local SPAN and RSPAN
Use the show monitor session command to view the sessions configured.
