Port mirroring

This function mirrors the replication of frames that transit on the specified port to
another port.
Specify a port as a mirror port, and another port as a port to be monitored. The
replication of frames that transit on the monitored port is passed to the mirror port.
However, note that the following restrictions apply.
Restrictions
Multiple mirror ports cannot be created at the same time. Multiple ports to be
monitored can be created at the same time, however.
A port set as the mirror port does not work as a normal switch port.
