Configuring EEE
Context
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.
