Configuring EEE

Configuring EEE


A device provides power for each interface. Even though an interface is idle, it consumes the same power as working interfaces. This wastes power. After the Energy Efficient Ethernet (EEE) function is configured on an electrical interface, the system reduces the power on the interface when the interface is idle and restores the power when the interface starts to transmit data. This reduces power consumption in the system.


Only electrical interfaces (including combo electrical interfaces ) support the EEE function. Optical interfaces do not support the EEE function.

If an electronic interface works at 10 Mbit/s after auto-negotiation, the EEE function does not take effect.


  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The interface view is displayed.

  3. Run energy-efficient-ethernet enable

    EEE function is enabled on the electrical interface.

    By default, the EEE function is disabled on an electrical interface.


    The EEE function takes effect only when it is configured on both ends of a link.

Verifying the Configuration

  • Run the display this command in the interface view to check whether the EEE function is enabled.
