Optimize EEE for
The switch can be set to optimize EEE for either best power saving or least traffic latency.
Port Configuration
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.
PerfectReach
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.
