Abstract: A network device includes ports to communicate with and provide power to devices connected thereto. The network device serves access points (APs) that connect wirelessly to client devices. The network device detects that a client device has wirelessly connected to or disconnected from an AP that is connected to the network device. Responsive to the detecting, the network device accesses predetermined power control information associated with the client device. If the power control information identifies one or more of the multiple ports, the network device selectively provides power to the identified one or more ports when the client device is detected as being connected to the AP and removes power from the identified one or more ports when the client device is detected as not being connected to the AP.
