3.4 ENERGY EFFICIENT ETHERNET
EEE is an abbreviation for Energy Efficient Ethernet defined in IEEE 802.3az.
This page allows the user to inspect and configure the current EEE port settings.
EEE is a power saving option that reduces the power usage when there is very low traffic use (or no traffic).
EEE works by powering down circuits when there is no traffic. When a port gets data to be transmitted, all circuits are powered up.
The time it takes to power up the circuits is named wakeup time. The default wakeup time is 17 µs for 1 Gbit links and 30 µs for
other link speeds. EEE devices must agree upon the value of the wakeup time to make sure that both the receiving and transmitting
device have all circuits powered up when traffic is transmitted. The devices can exchange information about the device’s wakeup
time using the LLDP protocol.
