Syntax

int <PORT-LIST> poe-allocate-by [usage|class|value]

Description

Allows you to manually allocate the amount of PoE power for a port by either its class or a defined value.

The default option for PoE allocation is usage, which is what a PD attached to the port is allocated. You can override this value by specifying the amount of power allocated to a port by using the class or value options.

Parameters

no
usage: (Default) The automatic allocation by a PD. The allowable PD requirements are lower than those specified for PSEs to allow for power losses along the Cat-5 cable.
class: Uses the power ramp-up signature of the PD to identify the device power class.
value: A user-defined level of PoE power allocated for that port.

Power classes and their values
Power class	Value
0	Depends on cable type and PoE architecture. Maximum power level output of 15.4 watts at the PSE.This is the default class; if there is not enough information about the load for a specific classification, the PSE classifies the load as class 0 (zero.)
1	Requires at least 4 watts at the PSE.
2	Requires at least 7 watts at the PSE.
3	15.4 watts
4	For PoE+Maximum power level output of 30 watts at the PSE.
