Configure the power supply 
priority for a PoE interface 

poe priority { critical | high | low } 

Optional 

low by default. 

 

After the PoE monitoring function is enabled, the system monitors the parameter values related to PoE 

power supply, PSE, PD, and device temperature in real time. When a specific value exceeds the 

limited range, the system will automatically take some measures to protect itself. 

PoE power supply converts AC power to specific DC power and supplies to PSEs. Exceptions of AC 

input voltage and DC output voltage of PoE power supply directly affect the PSEs to supply power to 

PDs. You can configure monitoring over AC input voltage and DC output voltage of PoE power supply. 

When a specific monitored item reaches the threshold, the system will generate trap message to notify 

the administrator of the PoE power supply exception. 

Follow these steps to configure PoE power supply monitoring:
