Description
Optimize EEE for The switch can be set to optimize EEE for either best power saving or
least traffic latency.
Port Configuration
Items
Description
Port
The switch port number of the logical port.
ActiPHY
Link down power savings enabled.
ActiPHY works by lowering the power for a port when there is no link. The port is
power up for short moment in order to determine if cable is inserted.
Perfect Reach
Cable length power savings enabled.
Perfect Reach works by determining the cable length and lowering the power for
ports with short cables.
EEE
Controls whether EEE is enabled for this switch port.
For maximizing power savings, the circuit isn't started at once transmit data is
ready for a port, but is instead queued until a burst of data is ready to be
transmitted. This will give some traffic latency.
If desired it is possible to minimize the latency for specific frames, by mapping the
frames to a specific queue (done with QOS), and then mark the queue as an urgent
queue. When an urgent queue gets data to be transmitted, the circuits will be
powered up at once and the latency will be reduced to the wakeup time.
EEE Urgent
Queues
Queues set will activate transmission of frames as soon as data is available.
Otherwise the queue will postpone transmission until a burst of frames can be
transmitted.
