A Software Defined Networking (SDN) controlled Power over Ethernet (PoE) management system includes a plurality of Power Sourcing Equipment (PSE) networking devices that are each configured to provide both power and data over a network connection to a powered device. An SDN controller device that is coupled to each of the plurality of PSE networking devices. The SDN controller device detects each of the plurality of PSE networking devices. The SDN controller may then receive, from each of the plurality of PSE networking devices, a first SDN communication that includes Power over Ethernet (PoE) information for that PSE networking device. The SDN controller device may then generate a management graphical user interface that is configured to display any of the PoE information that was received in the first SDN communications from each of the plurality of PSE networking devices.
