Chapter 24 Configuring SPAN and RSPAN
Configuring RSPAN
This example shows how to configure VLAN 901 as the source remote VLAN and how to configure the
destination port for ingress traffic on VLAN 5 by using a security device that supports 802.1Q
encapsulation:
Switch(config)# monitor session 1 source remote vlan 901
Switch(config)# monitor session 1 destination interface fastEthernet0/5 ingress vlan 5
Switch(config)# end
Removing Ports from an RSPAN Session
Beginning in privileged EXEC mode, follow these steps to remove a port as an RSPAN source for a
session:
This example shows how to remove port 1 as an RSPAN source for RSPAN session 1:
Switch(config)# no monitor session 1 source interface fastEthernet0/1
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 fastEthernet0/1 rx
The monitoring of traffic received on port 1 is disabled, but traffic sent from this port continues to be
monitored.
Step 5
show monitor [session session_number] Verify your entries.
Step 6
copy running-config startup-config (Optional) Save your entries in the configuration file.

Step 2
no monitor session session_number source
interface interface-id [, | -] [both | rx | tx]
Specify the characteristics of the RSPAN source port (monitored
port) to remove.
For session_number, specify 1 or 2.
For interface-id, specify the source port to no longer monitor. Valid
interfaces include physical interfaces and port-channel logical
interfaces (port-channel port-channel-number).
(Optional) Use [, | -] to specify a series or range of interfaces if they
were configured. Enter a space before and after the comma; enter
a space before and after the hyphen.
(Optional) Specify the direction of traffic (both, rx, or tx) to no
longer monitor. If you do not specify a traffic direction, both
transmit and receive are disabled.
