The amount of power allocated to PoE devices on the slot expressed in mWatts.
The amount of power allocated to a PoE device is based upon the PoE device
class and/or the port's extremePethPortViolationPrecedence setting. For
example, in the default configuration of extremePethPortViolationPrecedence
set to maxAdvertisedOperator(3), and the extremePethPortOperatorLimit set to
15400, a PoE device is allocated 15.4 watts.
