A Power-over-Ethernet (PoE) communication system dynamically provides power and data communications over a communications link. In an enterprise environment made up of one or more personal computing devices (e.g., personal or laptop computers), a switch determines a power classification for each device via a PoE control module that can be part of, for example, a Power Source Equipment/Powered Device (PSE/PD) system or a LAN-On-Motherboard/Powered Device (LOM/PD) system. A method of classifying power for each device includes detecting a device, polling it for power requirement information using a Layer 2 data link layer, receiving power requirement information from the device, and determining a power classification for the device. Power requirement information can include battery charge status, power load, power mode, etc., of the device. Various types of data packets can be used. The method can be repeated on a periodic basis, allowing power classification to be dynamic.
In a Power-over-Ethernet (PoE) system, a system for classifying power for a plurality of personal computing devices that each have a corresponding PoE control module from among a plurality of PoE control modules, comprising:
