Configuring SPAN and RSPAN
Command
Step 6
show monitor [session
session_number]
show running-config
Step 7
copy running-config
startup-config
To delete an RSPAN session, use the no monitor session session_number global configuration
command. To remove a destination port from the RSPAN session, use the no monitor session
session_number destination interface interface-id global configuration command. The ingress options
are ignored with the no form of the command.
This example shows how to configure VLAN 901 as the source remote VLAN in RSPAN session 2, to
configure Gigabit Ethernet source port 2 as the destination interface, and to enable forwarding of
incoming traffic on the interface with VLAN 6 as the default receiving VLAN.
Switch(config)# monitor session 2 source remote vlan 901
Switch(config)# monitor session 2 destination interface gigabitethernet1/0/2 ingress
vlan 6
Switch(config)# end
Specifying VLANs to Filter
