1-30 

2: System level 

max-power: Maximum PoE power, namely, maximum power that the device can provide for all PSEs. 

In consideration of the transient peak power effect, the maximum power available is 5% higher than 

the configured maximum power. The range, default value, granularity, and limit vary with devices. 

Use the poe power max-value command to configure the maximum PoE power. 

Use the undo poe power max-value command to restore the default. 

The default maximum PoE power varies with devices. 

Note that the configured maximum PoE power cannot exceed the rated PoE power. 

# Set the maximum PoE power to 2,000 watts for the device.

2: System level 

critical: Sets the power priority of a PoE interface to critical. The PoE interface whose power priority 

level is critical works in guaranteed mode, that is, power is first supplied to the PD connected to this 

critical PoE interface. 

high: Sets the power priority of a PoE interface to high. 

low: Sets the power priority of a PoE interface to low. 

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

Use the undo poe priority command to restore the default. 

By default, the power priority of a PoE interface is low.
