Mirror Setting
Port Mirroring is a method of monitoring network traffic that forwards a copy of
each incoming and/or outgoing packet from one port of a network switch to
another port where the packet can be studied. It enables the manager to keep
close track of switch performance and alter it if necessary.
Configuring the port mirroring by assigning a source port from which to copy
all packets, and a sniffer port where those packets will be sent.
The selection of the sniffer mode is as follows:
RX (receive) mode: This mode will duplicate the data that is sent to the source
and forwards it to the sniffer port.
