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 A6 as the monitoring port:
HPswitch(config)# mirror-port a6
To turn off monitoring:
HPswitch(config)# no mirror-port
