If you want to reconfigure the interface through a PoE configurationfile, you must first remove the command line configuration on the PoE interface.z You must use the same mode (command line or PoE configuration file) to configure the poemax-power max-power and poe priority { critical | high | low } commands.Configuring PoE Power ManagementConfiguring PD Power ManagementThe power priority of a PD depends on the priority of the PoE interface. The priority levels of PoEinterfaces include critical, high and low in descending order. Power supply to a PD is subject to PDpower management policies.All PSEs implement the same PD power management policies. When the PSE supplies power to aPD,z By default, no power will be supplied to a new PD if the PSE power is overloaded.z Under the control of a priority policy, the PD with a lower priority is first powered off to guaranteethe power supply to the new PD with a higher priority when the PSE power is overloaded.
