This section describes the commands that enable Green Ethernet power saving
features. Green Ethernet features are available on gigabit Ethernet ports operating
in copper mode (not fiber mode) and include the following capabilities:
• Energy Detect Mode—Reduces chip power by forcing a port PHY into a low-
power mode when the signal from a copper link partner is not present.
• Short Reach Mode—Tests the cable length at startup or when activated by
an administrator. If a short cable is detected, the port is put into low-power
mode. When the link goes down, low-power mode is disabled.
The Green Ethernet Mode properties are configurable per-port.

green-mode energy-detect

Use this command to enable Energy Detect mode on a gigabit Ethernet interface
(in Interface Config mode) or on all gigabit Ethernet interfaces (in Global Config
mode). Use the no form of the command to disable Energy Detect mode on the
interface(s).
