Port Mirroring is a method of monitoring network traffic that forwards
a copy of each incoming and/or outgoing packet from one port of the
Switch to another port where the packet can be studied. This enables
network managers to better monitor network performances.

the source port and forward to the Sniffer port.

Both (transmit and receive) mode: this mode will duplicate both the
data transmit from and data that send to the source port, then it will
forward to the Sniffer port.
