This section describes the commands used to configure and monitor Power Over Ethernet (PoE). PoE allows IP telephones, wireless LAN access points, and other appliances to receive power as well as data over existing LAN cabling without modifying the existing Ethernet infrastructure. PoE is only available on switches that contain a PoE controller.
PoE implements the PoE+ specification (IEEE 802.3at) for power sourcing equipment (PSE). IEEE 802.3at allows power to be supplied to Class 4 PD devices that require power greater than 15.4 Watts and up to 30.0 Watts. This allows the PoE+ enabled network switches and routers to be used for deployment with devices that require more power than the IEEE 802.3af specification allows. PoE+ IEEE 802.3at is compatible with IEEE 802.1af.
