Optimize EEE for
The switch can be set to optimize EEE for either best power saving or least traffic latency.
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.
PerfectReach 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
Squeue will postpone transmission until a burst of frames can be transmitted.
