Management of PoE Power to PDs

For each PoE-capable module or switch, you can configure how its PoE controller makes power available to attached powered devices (PDs). On a per module basis, you can configure:

• Real-time mode, in which the PoE controller calculates the power needed by a PD based on the actual power consumption of the attached devices.
• Class mode, in which the PoE controller manages power based on the IEEE 802.3af/.3at definition of the class limits advertised by the attached devices. In this mode, the maximum amount of power required by a device in the advertised class is reserved for the port, regardless of the actual amount of power being used by the device.

Power management to PDs is configured with the command set inlinepower management. PoE classes are defined in PoE Powered Device Classes.
