Table 5-17: Port Power Savings Configuration Parameters
Port Power Savings Configuration
Port
The device logical port number
ActiPHY
Link down power savings mode is 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 is 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 when
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.
