Admin > Port Mirroring
Port mirroring monitors and mirrors network traffic by
forwarding copies of incoming and outgoing packets
from one port to a monitoring port. Port mirroring can be
used as diagnostic tool and/or a debugging feature. Port
mirroring also enables switch performance monitoring.
Network administrators configure port mirroring by
selecting a target port to which the packets are copied,
and the source port(s) from which the packets are copied.
Port mirroring supports a maximum of one target port
and four source ports.
