This read-write TruthValue object enables or disables 802.3az Energy-Efficient Ethernet (EEE) on the Ethernet FE36E Card's port. Admins care about this because 802.3az lets the port drop into a low-power idle mode during quiet traffic periods, trading a small amount of latency on wake-up for reduced power draw on the card. An operator managing a large, power-constrained deployment of FE36E cards would enable this object on each port to reduce aggregate power consumption during off-peak hours, while a site running latency-sensitive traffic might leave it disabled to avoid the wake-up delay.
