Group 7 for 10/100/1000Mbps setting

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 follow:
TX (transmit) mode: this mode will duplicate the data transmit from the source port and forward to the sniffer port.
RX (receive) mode: this mode will duplicate the data that send to the source 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.
Note: The fiber port does not support sniffer function.
