Chapter 11 Configuring SPAN and RSPAN
Verifying Configuration
To monitor all VLANs on the trunk port, use the no monitor session session_number filter vlan global
configuration command.
EXAMPLE
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 2 through 5 and 9
to destination RSPAN VLAN 902:
Switch(config)# no monitor session 2
Switch(config)# monitor session 2 source interface gigabitethernet0/2 rx
Switch(config)# monitor session 2 filter vlan 2 - 5 , 9
Switch(config)# monitor session 2 destination remote vlan 902
Switch(config)# end
Verifying Configuration
To display the current SPAN or RSPAN configuration, use the show monitor user EXEC command. You
can also use the show running-config privileged EXEC command to display configured SPAN or
RSPAN sessions.
Configuration Example
This example shows how to set up SPAN session 1 for monitoring source port traffic to a destination
port. First, any existing SPAN configuration for session 1 is deleted, and then bidirectional traffic is
mirrored from source Gigabit Ethernet port 1 to destination Gigabit Ethernet port 2, retaining the
encapsulation method.
Switch(config)# no monitor session 1
Switch(config)# monitor session 1 source interface gigabitethernet0/1
Switch(config)# monitor session 1 destination interface gigabitethernet0/2
encapsulation replicate
Switch(config)# end
This example shows how to remove port 1 as a SPAN source for SPAN session 1:
Switch(config)# no monitor session 1 source interface gigabitethernet0/1
Switch(config)# end
This example shows how to disable received traffic monitoring on port 1, which was configured for
bidirectional monitoring:
Switch(config)# no monitor session 1 source interface gigabitethernet0/1 rx
The monitoring of traffic received on port 1 is disabled, but traffic sent from this port continues to be
monitored.
This example shows how to remove any existing configuration on SPAN session 2, configure SPAN
session 2 to monitor received traffic on all ports belonging to VLANs 1 through 3, and send it to
destination Gigabit Ethernet port 2. The configuration is then modified to also monitor all traffic on all
ports belonging to VLAN 10.
Switch(config)# no monitor session 2
Switch(config)# monitor session 2 source vlan 1 - 3 rx
Switch(config)# monitor session 2 destination interface gigabitethernet0/2
Switch(config)# monitor session 2 source vlan 10
Switch(config)# end
