Configuring Port Mirroring

one port to a monitoring port. Port mirroring can be used as a diagnostic tool as well as a debugging feature. Port
mirroring also enables switch performance monitoring.
Network administrators can configure port mirroring by selecting a specific port from which to copy all packets,
and other ports to which the packets copied.
