4.4.5 Port Power Saving Configuration
This page allows the user to configure the port power savings features.
What is EEE?
EEE is a power saving option that reduces the power usage when there is low or no traffic utilization.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 us for 1Gbit links and 30 us for other link speeds.
EEE devices must agree upon the value of the wakeup time in order to make sure that both the receiving and transmitting
device has all circuits powered up when traffic is transmitted. The devices can exchange wakeup time information using the
LLDP protocol. EEE works for ports in auto-negotiation mode, where the port is negotiated to either 1G or 100 Mbit full duplex
