Embodiment Construction

[0012] see figure 1 , is a schematic diagram of the network switch of the present invention. The network switch 100 includes a processor 110 and multiple PHY (Physical Layer, physical layer) chips 112 . Wherein, each PHY chip 112 includes a plurality of connection ports 113 . Each connection port 113 is used to connect an external device, such as a computer or server, to provide network connection service for the external device. In addition, each PHY chip 112 has a chip number, and each connection port 113 has a port identification number. E.g figure 1 As shown, it is assumed that the network switch 100 includes three PHY chips 112 , and each PHY chip 112 includes eight connection ports 113 . Wherein, the chip numbers of each PHY chip 112 are respectively a, b, and c, and the port identification numbers of each connection port 113 are numbers 1, 2, 3, . . . , 24, respectively.

[0013] In this embodiment, the network switch 100 includes multiple VLANs (Virtual Local Area...

Abstract

A network switch includes a processor and a plurality of PHY chips, and each PHY chip includes a plurality of connection ports. The processor has a built-in port information table, which is used to record the currently used connection ports in each PHY chip and the current operating status of each PHY chip, and detect whether there are all connection ports according to the port information table. Unused PHY chips. When detecting that all connection ports of any PHY chip are not in use, the processor sends a first control command to the corresponding PHY chip to control the corresponding PHY chip to enter a sleep state. The invention is used for power-saving management of network switches.

Description

technical field [0001] The invention relates to a network switch. Background technique [0002] Currently, network switches (such as Ethernet switches, Ethernet Switches) are widely used in various network environments, such as Internet cafes and enterprises. Most network switches include many connection ports, such as 24 or more than 48 connection ports. However, when only a small number of connection ports are used, all PHY (Physical Layer) chips of the network switch are still in normal operation, resulting in waste of power, which is contrary to the concept of energy saving and environmental protection. Contents of the invention [0003] In view of the above, it is necessary to provide a network switch, including a processor and a plurality of PHY chips, each PHY chip includes a plurality of connection ports, and the processor has a built-in port information table for recording the The currently used connection ports and the current operating status of each PHY chip,...
