Rx Tw – The link partner's time the receiver would like the transmitter

to hold off to allow time for it to wake from sleep.

Fallback Receive Tw – The link partner's fallback receive Tw.
A receiving link partner may inform the transmitter of an alternate

desired Tw_sys_tx. Since a receiving link partner is likely to have

discrete levels for savings, this provides the transmitter with additional

information that it may use for a more efficient allocation. Systems that

do not implement this option use a default that is the same as that of

the Receive Tw_sys_tx. (Refer to IEEE 802.3az for further information

on these system variables.)

Echo Tx Tw – The link partner's Echo Tx Tw value.
The respective echo values shall be defined as the local link partner’s

reflection (echo) of the remote link partner’s respective values. When a

local link partner receives its echoed values from the remote link

partner it can determine whether or not the remote link partner has

received, registered and processed its most recent values. For example,

if the local link partner receives echoed parameters that do not match

the values in its local MIB, then the local link partner infers that the

remote link partner’s request was based on stale information.

Echo Rx Tw – The link partner's Echo Rx Tw value.

Resolved Tx Tw – The resolved Tx Tw for this link (not the link

partner). The resolved value that is the actual “tx wakeup time” used

for this link (based on EEE information exchanged via LLDP).

Resolved Rx Tw – The resolved Rx Tw for this link (not the link

partner). The resolved value that is the actual “tx wakeup time” used

for this link (based on EEE information exchanged via LLDP).

EEE in Sync – Shows if the switch and link partner have agreed on

wake times:

Red - Switch and link partner have not agreed on wakeup times.

Green - Switch and link partner have agreed on wakeup times.
