LLDP-MED Mode
This mode is similar to the Class mode expect that each port determine the amount power it
reserves by exchanging PoE information using the
LLDP (Link Layer Discovery Protocol)
protocol
and reserves power accordingly. If no LLDP information is available for a port, the port will reserve
power using the class mode.
Note
For all modes: If a port uses more power than the reserved power for the port, the port is shut
down.
Power Management Mode
There are two modes for configuring when to shut down the ports:
Actual Consumption
In this mode the ports are shut down when the actual power consumption for all ports exceeds the
amount of power that the power supply can deliver or if the actual power consumption for a given
port exceeds the reserved power for that port. The ports are shut down according to the ports
priority. If two ports have the same priority the port with the highest port number is shut down.
Port Priority: Critical > High > Low.
