Enabling energy saving features on an Ethernet interface
Enabling auto power-down on an Ethernet interface
IMPORTANT:
Fiber ports do not support this feature.
When the auto power-down feature is enabled on an interface and the interface has been down for a
certain period of time, both of the following events occur:
•
The switch automatically stops supplying power to the interface.
•
The interface enters the power save mode.
The time period depends on the chip specifications and is not configurable.
When the interface comes up, both of the following events occur:
•
The switch automatically restores power supply to the interface.
•
The interface enters its normal state.

Enabling EEE energy saving for Ethernet interfaces in up state
IMPORTANT:
Fiber ports do not support this feature.
With the Energy Efficient Ethernet (EEE) energy saving feature, a link-up port enters the low power
state if it has not received any packet for a certain period of time. The time period depends on the
chip specifications and is not configurable. When a packet arrives later, the switch automatically
restores power supply to the interface and the port enters the normal state.
