Table 28. Green Ethernet Local Device information
Field Description
Cumulative Energy Saved on this
port due to Green mode(s) (Watts
* 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 TLV.
Rx_dll_enabled Status of the EEE capability negotiation on the local system.
Rx_dll_ready Data Link Layer ready: This variable indicates that the rx system
initialization is complete and is ready to update/receive LLDPDU
containing EEE TLV.
Time Since Counters Last Cleared Time Since Counters Last Cleared (since the time of power up, or after
EEE counters are cleared).
