Page Content

You can view PoE status and power usage on Huawei switches using the display poe device and display poe information commands.

Checking PoE Support

Before viewing PoE details, ensure your switch supports PoE. Only switches with PWR or PWH in the device name support PoE. Run the command:

CodeCopydisplay poe device

If the output shows device information, your switch supports PoE .

Viewing PoE Status

To see the current PoE running status, including power consumption and management mode, use:

CodeCopydisplay poe information

This command provides details such as:

  • Maximum output power set by the user
  • Current power consumption
  • Peak power consumption
  • Power management mode (auto/manual)
  • Port-level priority and status For a specific stack device, you can specify the device index to view its PoE information.

Enabling or Disabling PoE on Ports

PoE is usually enabled by default on downlink interfaces. To manage PoE on a specific port:

CodeCopysystem-viewinterface gigabitethernet 1/0/0undo poe enable // Disable PoEpoe enable // Enable PoE

If a powered device does not negotiate power correctly, you can force power on the interface using:

CodeCopypoe force-power

Each interface can supply up to 30 W for standard PoE devices, with a maximum distance of 100 meters .

PoE Standards and Power Levels

Huawei switches support multiple PoE standards:

  • 802.3af (PoE): up to 15.4 W per port
  • 802.3at (PoE+): up to 30 W per port
  • 802.3bt (PoE++): up to 60 W per port for high-power devices

Benefits of Viewing PoE

Monitoring PoE allows you to:

  • Ensure powered devices like IP phones, cameras, and APs receive sufficient power
  • Avoid overloading the switch's power budget
  • Manage power efficiently across multiple devices
  • Troubleshoot connectivity or power issues By combining these commands and understanding the PoE standards, you can effectively monitor and manage PoE on Huawei switches for both small and large network deployments .
