Problems solved by technology

However, from the appearance of the PoE port of the central AP, it is impossible to distinguish whether it is a power supply port (also called a power supply port) or a power extraction port (also called a power receiving port), which is easy to cause connection errors.

Embodiment Construction

[0059] The technical solution provided by the present application will be described below with reference to the drawings and specific embodiments.

[0060] see figure 1 , is a schematic structural diagram of a PoE device provided by an embodiment of the present invention. The PoE device 10 includes: a PoE port 101, an adaptive module 102, a PSE chip 101-1 and a PD chip 101-2. The PSE chip 101 - 1 and the PD chip 101 - 2 are respectively connected to an adaptive module 102 , and the PoE port 101 is connected to the adaptive module 102 .

[0061] The PSE chip 101-1 is connected to a power management system (not shown in the figure) of the PoE device, and can draw power from the power management system. The PD chip 101-2 is connected to the power management system of the PoE device, and can provide power for the power management system.

[0062] The adaptive module 102 is used to detect whether the PoE port 101 is connected to a power supply device; if the detection result is ...

Abstract

The invention discloses a port self-adaption method, apparatus and system. The method comprises the following steps: detecting, by a network device, whether a first port of the network device is connected to a power supply device; if the detection result is that the first port is connected to the power supply device, maintaining or switching the state of the first port to a power receiving state,and locking the first port as a power pumping port; and if the detection result is that the first port is not connected to the power supply device, and the network device has a power supply, switchingthe state of the first port to a power supply state. In this way, the first port can be adaptively switched to the power pumping port or a power supply port according to the accessed device, and theport does not need to be manually distinguished during device docking, thereby reducing the connection error rate.

Description

technical field [0001] The invention relates to the communication field, in particular to a port self-adaptation method and device. Background technique [0002] Power over Ethernet (PoE) is a technology that transmits Ethernet data and power (English: power) simultaneously using a twisted pair. Among them, electricity refers to the electricity provided (English: electricity). The Institute of Electrical and Electronic Engineers (Institute of Electrical and Electronic Engineers, IEEE) PoE standard defines that PoE devices include power sourcing equipment (power sourcing equipment, PSE) and powered devices (powered device, PD). A PSE is a device that provides electrical power. A PD is a device that draws power. [0003] Some network devices now provide both PSE power supply and PD power draw. For example, a central access point (access point, AP) in a distributed wireless local area network (wireless local area network, WLAN) is not only the PD drawing power from the swit...
