Mirror Settings

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 selections of the sniffer mode are as follows:

TX (transmit) mode: This mode will duplicate the data transmitted

from the source port and forward it to the sniffer port.

RX (receive) mode: This mode will duplicate the data sent to the

source and forward it to the sniffer port.

Both (transmit and receive ) mode: This mode will duplicate both

the data transmitted from and data sent to the source port, then it will

forward the data to the sniffer port.
