9. Use the Energy Detect Admin mode selection to enable or disable this option on the port.
With energy detect mode enabled, when the port link is down, the PHY automatically
goes down for a short period of time, and then wakes up to check link pulses. This allows
the switch to perform autonegotiation and save power consumption when no link partner
is present. The default value is Disabled.
10. Use the Short Reach Admin mode selection to enable or disable this option on the port.
With short reach mode enabled, PHY is forced to operate in low power mode irrespective
of the cable length. The default value is Disabled.
11. Use the EEE Admin mode selection to enable or disable this option on the port.
With EEE mode enabled, port transitions to low power mode during a link idle condition.
The default value is Disabled.
12. Click the Apply button.
The updated configuration is sent to the switch. Configuration changes take effect
immediately.
To refresh the screen, click the Update button.
To clear the configuration, resetting all statistics for the selected interface to default values, click
the Clear button.
The following table describes the nonconfigurable fields.

(LPI) state. Shows the total number of Rx LPI events since EEE
counters were last cleared.
Rx Low Power Idle Duration
(uSec)
This field indicates duration of Rx LPI state in 10 us increments. Shows
the total duration of Rx LPI since the EEE counters were last cleared.
Tx Low Power Idle Event Count This field is incremented each time MAC TX enters LPI state. Shows
the total number of Tx LPI events since EEE counters were last
cleared.
