Command Usage
â—† Setting a maximum power budget for the switch enables power to be centrally
managed, preventing overload conditions at the power source.
â—† If the power demand from devices connected to the switch exceeds the power
budget setting, the switch uses port power priority settings to limit the
supplied power.
Example
Console(config)#power mainpower maximum allocation 180
Console(config)#

the attached device. (Range: 1-30 characters)

supplied when a device is detected on the port, providing that the power
demanded does not exceed the port’s power budget or the switch’s power
budget.
