Energy Efficient Ethernet (EEE) supports the IEEE 802.3az standard for power savings in Ethernet networks for a select group of physical layer devices. A physical device that can support low power idle (LPI) mode is considered EEE-capable. Legacy devices that do not support EEE can be made EEE-compliant with an EEE-compliant PHY and an SDK version that allows the MAC device to interact with the PHY EEE functionality.
In a typical configuration, the EEE protocol communicates with the switch and the physical device to determine when to enter LPI mode during a period of inactivity, and to exit LPI mode when data transmission resumes.
Note
EEE is supported only on copper ports that have auto-negotiation enabled on them.
