Chapter 30 Configuring SPAN and RSPAN
Command
Step 5
On a switch other than the
Catalyst 3560E-12D switch:
monitor session session_number
destination remote vlan vlan-id
On the Catalyst 3560E0-12D switch:
monitor session session_number
destination remote vlan vlan-id
destination-port group {a | b | c}
Step 6 end
Step 7
show monitor [session session_number]
show running-config
Step 8 copy running-config startup-config
To monitor all VLANs on the trunk port, use the no monitor session session_number filter vlan global
configuration command.
This example shows how to remove any existing configuration on RSPAN session 2, configure RSPAN
session 2 to monitor traffic received on trunk port 2, and send traffic for only VLANs 1 through 5 and 9
to destination RSPAN VLAN 902.
Switch(config)# no monitor session 2
Switch(config)# monitor session 2 source interface gigabitethernet1/0/2 rx
Switch(config)# monitor session 2 filter vlan 1 - 5 , 9
Switch(config)# monitor session 2 destination remote vlan 902
Switch(config)# end
On the Catalyst 3560E-12D switch, this example shows how to remove any existing configuration on
RSPAN session 2, configure RSPAN session 2 to monitor traffic received on trunk port 2, and send
traffic for only VLANs 1 through 5 and 9 to destination RSPAN VLAN 902.
Switch(config)# no monitor session 1
Switch(config)# monitor session 1 source interface gigabitethernet0/2 rx
Switch(config)# monitor session 1 filter vlan 1 - 5 , 9
Switch(config)# monitor session 1 destination remote vlan 902 destination-port group a
Switch(config)# end
OL-9775-08
Purpose
Specify the RSPAN session and the destination remote VLAN
(RSPAN VLAN).
For session_number, enter the session number specified in Step 3.
For vlan-id, specify the RSPAN VLAN to carry the monitored traffic
to the destination port.
For the Catalyst 3560E-12D switch, enter destination-port group {a
| b | c} to specify the ports that carry RSPAN traffic.
Return to privileged EXEC mode.
Verify the configuration.
(Optional) Save the configuration in the configuration file.
