3-12.4 EEE
By using EEE power savings can be achieved at the expense of traffic latency. This
latency occurs due to that the circuits EEE turn off to save power, need time to boot up
before sending traffic over the link. This time is called "wakeup time". To achieve
minimal latency, devices can use LLDP to exchange information about their respective
tx 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.

NOTE: If your network without any devices which enables EEE
function then the table will show “No LLDP EEE information
found”.
Parameter description:
 Local Port :

 Tx Tw :
The link partner’s maximum time that transmit path can hold off sending data after
