Understanding EEE
Overview
Energy Efficient Ethernet (EEE) is a solution to save energy use on the Ethernet. EEE allows ports to enter low power idle
(LPI) mode during idle periods to reduce power consumption in Ethernet networks.
LPI is an energy-saving mode, in which ports send only the signals for keeping link connection. This significantly reduces
the number of sent signals.
Working Principle
According to the standard Ethernet specifications, ports of 100 Mbps and higher rates have the Active Idle State. To keep
links active, ports must send IDLE signals continuously even if no data is transmitted over the links. As a result, a large
amount of power is wasted.
EEE puts switch ports to LPI mode to save energy. In LPI mode, low link usage needs low power consumption.
EEE also
enables fast transition from LPI mode to normal operation, which ensures high-performance data transmission.
If an EEE-enabled port is always up and does not transmit data within tens of microseconds, it will enter LPI mode
automatically. When the port needs to transmit data, it restores the normal operation. This achieves power savings. To
enable EEE to take effect, the peer port must also support EEE.
Protocol Specification
Refer to IEEE 802.3az.
