Configuration Guide SPAN Configuration
The no monitor session session_number command allows you to delete the
source or destination port from the SPAN session in the global configuration
mode.
The destination port of SPAN participates in the STP.
When the SPAN is enabled, the configuration change has the following result.

If you change the VLAN configuration of the source port, the configuration
takes effect immediately.

If you change the VLAN configuration of the destination port, the
configuration takes effect immediately.

If you have disabled the source port or destination port, the SPAN does not
take effect.

If you add the source or destination port to an AP, this will remove the
source port or destination port from the SPAN.
Creating a SPAN Session and Specifying the Monitoring Port and Monitored
Port
To set up a SPAN session and sepcify the destination port and the source port,
execute the following commands.
Command Function
Ruijie(config)# monitor session
session_number source interface interface-id
[,| -] { both | rx | tx }
Specify the source port.
interface-id : Specify corresponding
interface id.
Ruijie(config)# monitor session
session_number destination interface
interface-id [ switch ]
Specify the destination port.
interface-id : Specify corresponding
interface id.
The switch parameter supports
exchange on the mirrored
destination port.
To delete a SPAN session, use the no monitor session session_number
command in the global configuration mode. To delete all the SPAN sessions,
use the no monitor session all command in the global configuration mode.
You can use the no monitor session session_number source interface
interface-id command or the no monitor session session_number destination
interface interface-id command to delete the source port or destination port in
the global configuration mode.
The following example shows how to create session 1. First, clear the
configuration of session 1, and then mirror the frames from port 1 to port 8. The
Show monitor session command allows you to verify your configuration.
Ruijie(config)# no monitor session 1
