Abstract
A power over Ethernet (PoE) power supplying method where power sourcing equipment (PSE) and a powered device exchange link layer discovery protocol data units (LLDPDUs). Each of the LLDPDUs includes two power values. Each of the power values indicates requested or allocated power for one of two sets of cable pairs of the Ethernet twisted pair connecting the PSE and the powered device. Accordingly, the supplied powers to the powered device at sets of cable pairs are independent from each other.
