5. From the Interface menu, select the interface.
6. Use the EEE Admin
Mode selection to enable or disable Energy Efficient Ethernet Admin
Mode on the port. With EEE mode enabled, the port transitions to low power mode during a
link idle condition. The default value is Disabled. If EEE Admin Mode is not supported, then
N/A is displayed.
7. In the EEE T
ransmit Wake Time field, enter the time for which MAC/switch must wait to go
back to active state from LPI state when it receives a packet for transmission. The range is
8 to 65535. The default value is 17.
8. Click the Apply button.

The following table describes the nonconfigurable fields.
Table 28. Green Ethernet Local Device information
Field Description
Cumulative Energy Saved on this
port due to Green mode(s) (W
atts
* Hours)
Cumulative energy saved due to all green modes enabled on this port in
(Watts * Hours).
Rx Low Power Idle Event Count This field is incremented each time MAC RX enters low-power idle (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.
Tx Low Power Idle Duration
(uSec)
This field indicates duration of Tx LPI state in 10 us increments. Shows the
total duration of
Tx LPI since the EEE counters were last cleared.
Tw_sys_tx (uSec) Integer that indicates the value of Tw_sys that the local system can
support.
Tw_sys_tx Echo (uSec) Integer that indicates the remote system's Transmit Tw_sys that was used
by the local system to compute the
Tw_sys that it wants to request from the
remote system.
Tw_sys_rx (uSec) Integer that indicates the value of Tw_sys that the local system requests
from the remote system.
Tw_sys_rx Echo (uSec) Integer that indicates the remote system’s Receive Tw_sys that was used
by the local system to compute the
Tw_sys that it can support.
Fallback Tw_sys (uSec) Integer that indicates the value of fallback Tw_sys that the local system
requests from the remote system.
Tx_dll_enabled Data Link Layer Enabled: Initialization status of the EEE transmit Data Link
Layer management function on the local system.
Tx_dll_ready Data Link Layer ready: This variable indicates that the tx system
initialization is complete and is ready to update/receive LLDPDU containing
EEE TL
