Configuring the PoE Monitoring Function 2181Configuring the PoEMonitoring FunctionThe PoE monitoring function involves monitoring of PoE power, PSE and PD.■ Monitoring PoE power means monitoring the voltage of the PoE power.■ When the current power utilization of the PSE is above or below the alarmthreshold for the first time, the system will send a Trap message.■ When the PSE starts or stops supplying power to a PD, the system will send aTrap message, too.Configuring a PowerAlarm Threshold for thePSEFollow these steps to configure a power alarm threshold for the PSE:Upgrading PSEProcessing SoftwareOnlineYou can upgrade the PSE processing software online in either of the followingmodes:■ refresh modeThis mode enables you to update the PSE processing software without deleting it.Normally, you can upgrade the PSE processing software in the refresh modethrough the command line.■ full modeThis mode deletes the PSE processing software and reloads it. When the PSEprocessing software is damaged (in this case, you can execute none of PoEcommands successfully), you can upgrade the PSE processing software in fullmode to restore the PSE function.Configurethe powerpriority for aPoEinterface.Configure the powerpriority for the PoEinterface in PoE interfaceviewinterfaceinterface-typeinterface-numberUse either approach.By default, the powerpriority of a PoEinterface is low.poe priority { critical |high | low }Configure the powerpriority for the PoEinterface in PoEconfiguration file viewpoe-profileprofile-name [ index ]poe priority { critical |high | low }Configure a PD power managementpriority policypoe pd-policy priority OptionalBy default, no PDpower managementpriority policy isconfigured.To do...
