Column Meaning
If the short reach operational status is active, this field displays one of the
following reasons:
•
Short cable < 10m
•
Forced
EEE Admin Mode EEE Admin Mode is enabled or disabled.
Transmit Idle Time It is the time for which condition to move to LPI (low-power idle) state is satisfied, at
the end of which MAC TX transitions to LPI state. The range is 0 to 429496729. The
default value is 0.
Transmit Wake Time It is the time for which MAC / switch has to wait to go back to ACTIVE state from LPI
state when it receives packet for transmission. The range is 0 to 65535. The default
value is 0.
Rx Low Power Idle Event
Count
This field is incremented each time MAC RX enters LPI state. Shows the total number
of Rx LPI Events since EEE counters are last cleared.
Rx Low Power Idle Duration
(μSec)
This field indicates duration of Rx LPI state in 10 μs increments. Shows the total
duration of Rx LPI since the EEE counters are last cleared.
Tx Low Power Idle Event
Count
This field is incremented each time MAC TX enters LP IDLE state. Shows the total
number of Tx LPI Events since EEE counters are last cleared.
Rx Low Power Idle Duration
(μSec)
This field indicates duration of Tx LPI state in 10 μs increments. Shows the total
duration of Tx LPI since the EEE counters are last cleared.
Tw_sys_tx (μSec) Integer that indicates the value of Tw_sys that the local system can support. This
value is updated by the EEE DLL Transmitter state diagram.
Tw_sys Echo (μSec) 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 (μSec) Integer that indicates the value of Tw_sys that the local system requests from the
remote system. This value is updated by the EEE Receiver L2 state diagram.
Tw_sys_rx Echo (μSec) Integer that indicates the remote systems Receive Tw_sys that was used by the local
system to compute the Tw_sys that it can support.
Fallback Tw_sys (μSec) Integer that indicates the value of fallback Tw_sys that the local system requests
from the remote system.
Remote Tw_sys_tx (μSec) Integer that indicates the value of Tw_sys that the remote system can support.
Remote Tw_sys Echo
(μSec)
Integer that indicates the value Transmit Tw_sys echoed back by the remote system.
Remote Tw_sys_rx (μSec) Integer that indicates the value of Tw_sys that the remote system requests from the
local system.
Remote Tw_sys_rx Echo
(μSec)
Integer that indicates the value of Receive Tw_sys echoed back by the remote
system.
Remote Fallback Tw_sys
(μSec)
Integer that indicates the value of fallback Tw_sys that the remote system is
advertising.
Tx_dll_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 TLV. This variable
is updated by the local system software.
