An interface enters thepower save mode if it has not received any packet for a certain period of time (this interval depends onthe specifications of the chip, and is not configurable). When a packet arrives later, the interface entersits normal state.To enable auto power-down on an Ethernet interface:Step Command Remarks1. Enter system view. system-view N/A2.
