Green Ethernet

This page allows the user to configure the port power savings features.
EEE is an abbreviation for Energy Efficient Ethernet defined in IEEE 802.3az.
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 mode.
For ports that are not EEE-capable the corresponding EEE checkboxes are grayed out and thus
impossible to enable EEE for.
The EEE port settings relate to the currently selected stack unit, as reflected by the page header.
When a port is powered down for saving power, outgoing traffic is stored in a buffer until the port is
powered up again. Because there are some overhead in turning the port down and up, more power
can be saved if the traffic can be buffered up until a large burst of traffic can be transmitted.
Buffering traffic will give some latency in the traffic.
