and rx "wakeup time ", as a way to agree upon the minimum wakeup time they need.
This page provides an overview of EEE information exchanged by LLDP.
LLDP Neighbors EEE Information
The displayed table contains a row for each interface.
If the interface does not support EEE, then it displays as "EEE not supported for this interface".
If EEE is not enabled on particular interface, then it displays as "EEE not enabled for this interface".
If the link partner doesn't support EEE, then it displays as "Link partner is not EEE capable.
The columns hold the following information:
Local Interface
The interface at which LLDP frames are received or transmitted.
Tx Tw
The link partner's maximum time that transmit path can hold-off sending data after deassertion of LPI.
Rx Tw
The link partner's time that receiver would like the transmitter to hold-off to allow time for the receiver to
wake from sleep.
Fallback Receive Tw
The link partner's fallback receives 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 default the value to be the same as that of the Receive Tw_sys_tx.
Echo Tx Tw
The link partner's Echo Tx Tw value. The respective echo values shall be defined as the local link partner
reflection (echo) of the remote link partners 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 partners request was based on stale information.
