IEEE 802.3at LLDP provides smart power budget control behavior to fulfill the
needs of higher end setups requiring exact high power delivery. By using the
ongoing dynamic re-negotiation function of the IEEE802.3at LLDP, the switch can
perform more intelligently by dynamically reallocating power to the PDs. The
switch implements the 2-event and Link Layer Discovery Protocol (LLDP) PoE into
the system for efficient power budget negotiation between PSE and PD devices.
The Power Budget can limit the consumption of PoE port and ensure the
PoE port can still get the pre-allocatied power from the budget. The range of
Power Budget is 0.4 to 32 Watt. The max effective power budget of 802.3af
powering mode is 15.4 Watt even if the power budget is set to 32 Watts.
Power Priority lets the PoE port with higher priority to deliver power during
the limit power budget. There are three priorities (Critical, High and Low).
After configuring, please click the Apply button to enable and perform the
configurations.
Next, we illustrate how to configure IEEE 802.3at LLDP. Assume the PD is ready to
the configuration for IEEE 802.3at LLDP, we only need to confirm the switch
configuration.
Enable the LLDP (refer to 4.12.5). By the port of the switch connected to the PD
(ex. Port 4), set PoE Mode is Enable and Powering Mode is 802.3at(LLDP). When
the switch and the PD are ready to IEEE802.3at LLDP, IEEE 802.3at LLDP starts
operation. Finally, see the result on Poe Status (refer to 4.4.5).
