Ethernet
Energy-efficient
Ethernet (EEE) reduces power consumption of physical layer devices (PHYs) during idle periods. EEE allows Dell EMC
Networking devices to conform to green computing standards.
An Ethernet link consumes power when a link is idle. EEE allows Ethernet links to use Regular Power mode only during data transmission.
EEE is enabled on devices that support LOW POWER IDLE (LPI) mode. Such devices save power by entering LPI mode during periods
when no data is transmitting.
In LPI mode, systems on both ends of the link saves power by shutting down certain services. EEE transitions into and out of LPI mode
transparently to upper-layer protocols and applications.
EEE advertises during the auto-negotiation stage. Auto-negotiation detects abilities supported by the device at the other end of the link,
determines common abilities, and
configures
joint operation.
Auto-negotiation performs at power-up, on command from the LAN controller, on detection of a PHY error, or following Ethernet cable re-
connection. During the link establishment process, both link partners indicate their EEE capabilities. If EEE is supported by both link
partners for the negotiated PHY type, EEE functions independently in either direction.
