IEEE 802.3az refers to this state of idleness as Low Power Idle (LPI). When enabled, in the LPI mode, both ends of the Ethernet link disable operating circuitry that are not needed and save power.
Note
Energy-Efficient Ethernet can be activated only if devices at both ends of the physical link support EEE.eee
