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.
