Port Speed & Duplex Mode
After plugging the selected cable to a specific port, the system uses
auto-negotiation to determine the transmission mode, auto-
detecting the network speed (10Mbps or 100Mbps) for any new
twisted-pair connection.
If the attached device does not support auto-negotiation or has
auto-negotiation disabled, an auto-sensing process is initiated to
select the speed and half-duplex mode is selected.
