Embodiments described herein include a Power over Ethernet (PoE) enabled device that uses 2-event classification when allocating power to coupled powered devices (PDs). If the 2-event classification is successful, power sourcing equipment (PSE) on the PoE device allocates a maximum power allotment to the PD. Once powered on, the PD may determine it does not require the maximum power allotment and negotiate a reduction in the power allotted to the PD.
