Green Ethernet
This chapter shows you how to configure the Switch to reduce the power consumed by switch ports.
33.1 Green Ethernet Overview
Green Ethernet reduces switch port power consumption in the following ways.
IEEE 802.3az Energy Efficient Ethernet (EEE)
If EEE is enabled, both sides of a link support EEE and there is no traffic, the port enters Low Power
Idle (LPI) mode. LPI mode turns off some functions of the physical layer (becomes quiet) to save
power. Periodically the port transmits a REFRESH signal to allow the link partner to keep the link
alive. When there is traffic to be sent, a WAKE signal is sent to the link partner to return the link to
active mode.
Auto Power Down
Auto Power Down
turns off almost all functions of the port’s physical layer functions when the link
is down, so the port only uses power to check for a link up pulse from the link partner. After the link
up pulse is detected, the port wakes up from
Auto Power Down
and operates normally.
