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.

Abstract translation: 网络设备包括与其连接的设备进行通信和向其提供电力的端口。 网络设备提供无线连接到客户端设备的接入点（AP）。 网络设备检测到客户端设备已经与连接到网络设备的AP无线连接或断开连接。 响应于检测，网络设备访问与客户端设备相关联的预定功率控制信息。 如果功率控制信息识别多个端口中的一个或多个，则当客户端设备被检测为连接到AP时，网络设备选择性地向所识别的一个或多个端口提供电力，并且当从所识别的一个或多个端口移除电力时， 检测到客户端设备未连接到AP。
