摘要：A network device (10) may be provided with a PHY layer process unit (40)configured to execute a process of a PHY layer, a determination unit (36, 38) configuredto determine that a link state is a link up state or a link down state by utilizinginformation given from the PHY layer process unit (40), and a first control unit (36, 38)configured to control an electrical power supply for the PHY layer process unit (40). Thefirst control unit (36, 38) may be configured to stop a continuous electrical power supplyfor the PHY layer process unit (40) if the determination unit (36, 38) determines that thelink state is the link down state during a first period in which the continuous electricalpower supply for the PHY layer process unit (40) is being performed, perform atemporary electrical power supply for the PHY layer process unit (40) during a secondperiod after the continuous electrical power supply for the PHY layer process unit (40) isstopped, and commence the continuous electrical power supply for the PHY layerprocess unit (40) if the temporary electrical power supply for the PHY layer process unit(40) is performed during the second period and the determination unit (36, 38)determines that the link state is the link up state.
