Field Description
Cumulative Energy Saved
on this port due to Green
mode(s) (W
atts * Hours)
The cumulative energy in watts multiplied by hours that is saved through the
green modes that are enabled on this port.
Rx Low Power Idle Event
Count
The number of Rx low-power idle (LPI) events since the EEE counters were
cleared.
The counter increments each time that the MAC Rx enters the LPI state.
Rx Low Power Idle Duration
(uSec)
The duration of the Rx LPI state since the EEE counters were cleared. The
duration of the Rx LPI state is displayed in 10 uSec increments.
Tx Low Power Idle Event
Count
The number of Tx LPI events since the EEE counters were cleared. The counter
increments each time that the MAC
Tx enters the LPI state.
Tx Low Power Idle Duration
(uSec)
The duration of the Tx LPI state since the EEE counters were cleared. The
duration of the
Tx LPI state is displayed in 10 uSec increments.
Tw_sys_tx (uSec) The value in uSecs of Tw_sys that the switch can support.
Tw_sys_tx Echo (uSec) The remote system’s transmitted Tw_sys in uSecs that was used by the switch to
compute the
Tw_sys in requests to the remote system.
Tw_sys_rx (uSec) The value of Tw_sys in uSecs that the switch requests from the remote system.
Tw_sys_rx Echo (uSec) The remote system’s received Tw_sys in uSecs that was used by the switch to
compute the
Tw_sys that it can support.
Fallback Tw_sys (uSec) The value in uSecs of the fallback Tw_sys that the switch requests from the
remote system.
Tx_dll_enabled Indicates the initialization status of the EEE transmit Data Link Layer
management function on the switch.
Tx_dll_ready Indicates whether the Data Link Layer is ready and the Tx system initialization is
complete and ready to update or receive LLD PDUs containing EEE
TLVs.
Rx_dll_enabled Indicates the status of the EEE capability negotiation on the switch.
Rx_dll_ready Indicates whether the Data Link Layer is ready and the Rx system initialization is
complete and ready to update or receive LLD PDUs containing EEE
TLVs.
Time Since Counters Last
Cleared
The period since the counters were cleared or the switch was powered up.
