z If you mirror traffic to a port, you must configure a monitor port with the mirroring-group
monitor-port command or the monitor-port command. For information about the two commands,
refer to the part talking about mirroring.
z Traffic mirroring and local port mirroring share the same monitor port.
Related commands: display qos-interface mirrored-to.
