Configuring the monitor port
Syntax:
no mirror-port [< port-num >]
This command assigns or removes a monitoring port, and must be executed from the global configuration level. Removing the monitor port disables port monitoring and resets the monitoring parameters to their factory-default settings.
For example, to assign port 6 as the monitoring port:
switch(config)# mirror-port 6
To turn off monitoring:
switch(config)# no mirror-port
