Example for Configuring PoE on Huawei Router

Networking Requirements

Figure 1 shows that Router are deployed at the access layer in current network. The IP phone connected to the router is deployed outdoors and the AP is deployed on the external wall of the office. The location makes it difficult to connect power supplies to these devices. The user wants Router to provide power for these devices and save the deployment costs. As the office network of a bank, AP1 cannot be powered off and should be configured with the highest power supply priority. IP Phone1 with a large amount of services needs to obtain power supply with high priority and generally cannot be powered off.

Configuration Roadmap

The configuration roadmap is as follows:

1. Configure the power management mode as automatic mode so that PDs can be flexibly

managed.

2. Configure the maximum output power for the device to ensure the device obtains the power as required.

3. Configure the power supply priority on Ethernet0/0/4 and Ethernet0/0/6 to preferentially

provide power for IP Phone1 and AP1.

4. Configure the maximum output power on Ethernet0/0/4 and Ethernet0/0/6 to limit the

power of the corresponding interface and ensure security of the device.

The configuration overview:

Step 1 Configure the power management mode of the device as automatic mode.

Step 2 Configure the maximum output power of the device as 100 W.

Step 3 If IP Phone1 and AP1 respectively requires power of 10 W and 15 W, configure the maximum output power on Ethernet0/0/4 and Ethernet0/0/6.

[Router-Ethernet0/0/4] poe enable

[Router-Ethernet0/0/4] poe power 10000

Warning: This operation may power off the PD of this port.Continue?[Y/N]:y

Info: Succeed in setting maximum power of port.

[Router-Ethernet0/0/4] quit

[Router] interface ethernet 0/0/6

[Router-Ethernet0/0/6] poe enable

[Router-Ethernet0/0/6] poe power 15000

Warning: This operation may power off the PD of this port.Continue?[Y/N]:y

Info: Succeed in setting maximum power of port.

[Router-Ethernet0/0/6] quit

NOTE

By default, the PoE function is enabled on all interfaces. You need to run the poe enable only after running the undo poe enable command to disable the PoE function.

Step 4 Configure the power priority on Ethernet0/0/4 as High and power priority on Ethernet0/0/6 as Critical.

[Router] interface ethernet 0/0/4

[Router-Ethernet0/0/4] poe priority high

Warning: This operation may power off some PD with lower priority.Continue?[Y/N] :y

[Router-Ethernet0/0/4] quit

[Router] interface ethernet 0/0/6

[Router-Ethernet0/0/6] poe priority critical

Warning: This operation may power off some PD with lower priority.Continue?[Y/N] :y

[Router-Ethernet0/0/6] quit

Step 5 Check the configuration.
