energy-efficient-ethernet enable

Function

The energy-efficient-ethernet enable command enables the Energy Efficient Ethernet (EEE) function on an electrical interface.

The undo energy-efficient-ethernet enable command disables the EEE function on an electrical interface.

By default, EEE is disabled on an electrical interface.

Usage Guidelines

Usage Scenario

The system provides power for each interface. Even though an interface is idle, it consumes the same power as working interfaces. The energy-efficient-ethernet enable command enables the system to reduce the power on an interface when the interface is idle and restore the power when the interface starts to transmit data. This reduces system power consumption.

Prerequisites

If an electrical interface works in non-auto negotiation mode, run the negotiation auto command to enable auto-negotiation.

Precautions

The EEE function can be configured only on electrical interfaces (including combo electrical interfaces). Optical interfaces do not support the EEE function.
If an electrical interface works at 10 Mbit/s after auto-negotiation, the EEE function does not take effect.
The S5731-H, S5731-S, S5731S-H, S5731S-S, S6720-EI, and S6720S-EI do not support the EEE function.
Enabling or disabling EEE on an interface will trigger re-negotiation. During the negotiation, the interface may change to Down state, which causes short service interruption. Therefore, determine whether the operation is allowed before you run this command.
If auto-negotiation is disabled on an interface, the EEE configuration is automatically deleted.
