guaranteed in case of mirroring only one physical interface.
Controlling port has the following restrictions:
– Port cannot act as monitored and controlling port at the same time.
– Port cannot belong to the port group.
– IP interface should not be set for this port.
– GVRP must be disabled for this port.
Monitored port has the following restrictions:
