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.
- 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.
Procedure
- Run system-view
The system view is displayed.
- Run interface interface-type interface-number
The interface view is displayed.
- 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.
