Abstract
A power sourcing equipment (PSE) device including a power over Ethernet (PoE) interface. A processor is coupled to the PoE interface. A memory is coupled to the processor and includes instruction that, when executed by the processor, cause the processor to perform a number of functions. The processor may supply power at a first power level to a PD that is coupled to the PoE interface. The processor may then determine an actual power consumption of the PD. The processor may then send a first Link Layer Discovery Protocol (LLDP) packet to the PD over the PoE interface that includes first proposed power level information that is based on the actual power consumption of the PD. Then processor may then supply power to the PD at a second power level that is different from the first power level.
