Description
Use the mirroring-group monitor-port command to configure the destination port.
Use the undo mirroring-group monitor-port to remove the configuration of the
destination port.
Note the following when you configure the destination port:
LACP must be disabled on the mirroring destination port and STP is

The destination port for remote mirroring must be an Access port.
After a port is configured as a reflector port, the switch does not allow you to
change the port type and its default VLAN ID.
