Abstract
A network switch includes a plurality of physical layer (PHY) chips and a processor. Each of the PHY chips includes a plurality of network interfaces configured to connect to external network devices. The processor includes a port information (PI) table configured to record a working state of each PHY chip and to record used network interfaces of each PHY chip. When there are one or more PHY chips which network interfaces are all not used, the processor controls the one or more PHY chips to work in a sleep state.

A network switch, comprising:
- a plurality of physical layer (PHY) chips, each of the PHY chips comprising a plurality of network interfaces configured to connect to external network devices;
- and
- a processor comprising a port information (PI) table configured to record a working state of each PHY chip and to record used network interfaces of each PHY chip, the processor detecting if there is one or more PHY chip having network interfaces that are all not used according to the PI table, and controlling the detected one or more PHY chip which network interfaces that are all not used to work in a sleep state.
