LLDP/PoE

This page provides a status overview all LLPD PoE neighbours. The displayed table contains a row for each port on which
an LLDP PoE nighbours is detected.
LOCATION：Monitor>LLDP>PoE
Parameters:
Items Description
Local Port The port 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: Critical, High and
Low. If the power priority is unknown it is indicated as "Unknown"
Maximum The Maximum Power Value contains a numerical value that indicates the maximum power in watts
Power 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 circuits EEE
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", as
a way to agree upon the minimum wake up time needed.
