Embodiment Construction

[0035] The solution of the embodiment of the present invention is mainly: by detecting whether the power receiving device has a MAC address, when the power receiving device does not have a MAC address, start the power supply process for the power receiving device according to the priority of the power supply port set in advance, when the power receiving device When the device has a MAC address, judge whether the MAC address is stored in the preset MAC address table. When the MAC address is not stored in the preset MAC address table, update the MAC address to the MAC address table, and follow the preset According to the predetermined priority arrangement rules, set the corresponding power supply priority for the MAC address, and supply power to the powered device according to the power supply priority corresponding to the MAC address of the powered device.

[0036] Such as figure 1 As shown, an embodiment of the present invention proposes a method for supplying power to a power...

Abstract

The invention relates to a method and a device for supplying power for a powered device. The method comprises the following steps of: detecting whether the powered device inserted in a power supply port of the power supply device has the MAC (Media Access Control) address or not; and supplying power for the powered device according to the preset priority of the power supply port when the MAC address is not available in the powered device. The invention ensures that the powered device can flexibly select the power supply port of the power supply device, breakthroughs the limitation that the powered device mush select the corresponding fixed port of the power supply device in order to obtain a certain special priority, improves the management efficiency of the power supply system to the powered device and ensures that the whole POE (Power Over Ethernet) power supply network can be more flexibly constructed.

Description

technical field [0001] The present invention relates to the field of Ethernet power supply, in particular to a method and device for supplying power to a powered device according to network attributes of the powered device such as a MAC address. Background technique [0002] With the official release of the IEEE802.3at standard, POE (Power over Ethernet, Power over Ethernet) technology has become a hot spot of people's attention. How to manage the powered device (PD, Power Device) reasonably and effectively according to the network environment has become a POE key to technological development. [0003] At present, the power supply equipment (PSE, Power Supply Equipment, taking a switch with POE function as an example) sets the power supply priority of the powered equipment mainly based on the power supply port of the power supply equipment, that is, through artificial settings, each power supply port of the power supply equipment is set to For different priorities, when the...
