Enabling Ethernet interface auto power-down function

To save power, enable the auto power-down function on Ethernet interfaces. An interface enters the power
save mode if it has not received any packet for a certain period of time (this interval depends on the
specifications of the chip, and is not configurable). When a packet arrives later, the interface enters its
normal state.
To enable auto power-down on an Ethernet interface:
Step...
1. Enter system view
2. Enter Ethernet
interface view or port
group view
3. Enable auto power-
down on an Ethernet
interface
When you connect an interface enabled with auto power-down to a device, if the link cannot go up
properly, disable auto power-down on the interface and try again.

Setting Ethernet interface speed options for auto negotiation

Speed auto negotiation enables an Ethernet interface to negotiate with its peer for the highest speed that
both ends support by default. narrow down the speed option list for negotiation.
