Green Ethernet

Cisco Small Business 200E Series Advanced Smart Switch Command Reference

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.

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).

green-mode energy-detect [interface]

no green-mode energy-detect [interface]

Indicates whether Link Aggregation Control Protocol (LACP) 
is enabled or disabled on this port.

Indicates whether flow control is enabled or disabled.

Displays detailed statistics for an interface or for the entire 
switch.

Configures the speed of an Ethernet interface when not 
using auto-negotiation.

Enables auto-negotiation on a port.
