Description
Local Port
The port for this switch on which the LLDP frame was received.
Power Type
The Power Type represents whether the device is a Power Sourcing Entity (PSE) or Power
Device (PD).
If the Power Type is unknown it is represented as "Reserved".
Power Source
The Power Source represents the power source being utilized by a PSE or PD device. If the
device is a PSE device it can either run on its Primary Power Source or its Backup Power
Source. If it is unknown whether the PSE device is using its Primary Power Source or its
Backup Power Source it is indicated as "Unknown”. If the device is a PD device it can either
run on its local power supply or it can use the PSE as power source. It can also use both its
local power supply and the PSE. If it is unknown what power supply the PD device is using it is
indicated as "Unknown”.
Power Priority
Power Priority represents the priority of the PD device, or the power priority associated with
the PSE type device's port that is sourcing the power. There are three levels of power
priority. The three levels are: Critical, High and Low. If the power priority is unknown it is
indicated as "Unknown”.
Maximum Power
The Maximum Power Value contains a numerical value that indicates the maximum power in
watts required by a PD device from a PSE device, or the minimum power a PSE device is
capable of sourcing over a maximum length cable based on its current configuration. The
maximum allowed value is 102.3 W. If the device indicates value higher than 102.3 W, it is
represented as "reserved”.

LLDP EEE
By using EEE, power savings can be achieved at the expense of traffic latency. This latency occurs because the EEE
circuits turn off to save power and 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”. This page provides an overview of EEE information exchanged by LLDP.
