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

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.
