Chapter24 Configuring SPAN and RSPAN
Configuring SPAN and RSPAN
To delete a SPAN session, use the no monitor session session_number global configuration command.
To remove a source port or VLAN from the SPAN session, use the no monitor session session_number
source {interface interface-id | vlan vlan-id} global configuration command. To remove the RSPAN
VLAN from the session, use the no monitor session session_number destination remote vlan vlan-id.
This example shows how to remove any existing RSPAN configuration for session 1, configure RSPAN
session 1 to monitor multiple source interfaces, and configure the destination as RSPAN VLAN 901.
Switch(config)# no monitor session 1
Switch(config)# monitor session 1 source interface gigabitethernet0/1 tx
Switch(config)# monitor session 1 source interface gigabitethernet0/2 rx
Switch(config)# monitor session 1 source interface port-channel 12
Switch(config)# monitor session 1 destination remote vlan 901
Switch(config)# end
Step3 monitor session session_number source
{interface interface-id | vlan vlan-id} [, | -]
[both | rx | tx]
Specify the RSPAN session and the source port (monitored port).
For session_number, the range is 1 to 66.
Enter a source port or source VLAN for the RSPAN session:
•For interface-id, specify the source port to monitor. Valid
interfaces include physical interfaces and port-channel logical
interfaces (port-channel port-channel-number). Valid
port-channel numbers are 1 to 48.
•For vlan-id, specify the source VLAN to monitor. The range is 1
to 4094 (excluding the RSPAN VLAN).
Note A single session can include multiple sources (ports or
VLANs), defined in a series of commands, but you cannot
combine source ports and source VLANs in one session.
(Optional) [, | -] Specify a series or range of interfaces. Enter a space
before and after the comma; enter a space before and after the
hyphen.
(Optional) Specify the direction of traffic to monitor. If you do not
specify a traffic direction, the source interface sends both sent and
received traffic.
•both—Monitor both received and sent traffic.
•rx—Monitor received traffic.
•tx—Monitor sent traffic.
Step4 monitor session session_number
destination remote vlan vlan-id Specify the RSPAN session and the destination RSPAN VLAN.
For session_number, enter the number defined in Step 3.
For vlan-id, specify the source RSPAN VLAN to monitor.
Step5 end Return to privileged EXEC mode.
Step6 show monitor [session session_number]
show running-config
Verify the configuration.
Step7 copy running-config startup-config (Optional) Save the configuration in the configuration file.
