z 

When the PoE power is insufficient, power is first supplied to PoE interfaces with a higher priority 

level. 

z 

If a PoE configuration file is already applied to a PoE interface, you need to remove the 

application of the file to the PoE interface before configuring the interface in PoE-profile view. 

z 

If a PoE configuration file is applied to a PoE interface, you need to remove the application of the 

file to the PoE interface before configuring the interface in PoE interface view. 

z 

If two PoE interfaces have the same priority level, the PoE interface with a smaller ID has the 

higher priority level.

2: System level 

critical: Sets the power priority level of the PSE to critical. The PSE whose power priority level is 

critical works in guaranteed mode, that is, power is first supplied to the PSE. 

high: Sets the power priority of the PSE to high. 

low: Sets the power priority of the PSE to low. 

pse pse-id: Specifies a PSE ID.   

Use the poe priority command to configure a power priority level for the PSE. 

Use the undo poe priority command to restore the default. 

By default, the power priority level of the PSE is low.
