Usage Guidelines

Usage Scenario

After a PoE switch is powered off and then restarts, interfaces on this device can be powered on again only after a certain period. As a result, PDs connected to these interfaces are powered off within this period. To shorten the time during which the PDs are powered off, you can run the poe fast-on enable command on the PoE switch. After the PoE switch is powered off and then restarts, PoE interfaces can rapidly resume power supply to PDs.

Precautions

This command takes effect only during cold startup of the device.
The poe fast-on enable command does not generate any configuration but always takes effect after being executed until the undo poe fast-on enable command is executed. To determine whether the fast power-on configuration takes effect, run the display poe power-state command to check the fast-on field.

Example

# Enable fast power-on for GE0/0/1.

<HUAWEI> system-view
[HUAWEI] interface gigabitethernet 0/0/1
[HUAWEI-GigabitEthernet0/0/1] poe fast-on enable
Warning: This configuration takes effect only after a cold restart. Continue?[Y/N]:y
Warning: Ensure that the power required by the connected PD does not exceed the rated PoE power provided by the device. Otherwie, the device may not start normally. Continue?[Y/N]:y

# Disable fast power-on for GE0/0/1.
