•
Maximum power a PSE is allowed to supply to a PD
•
During device operation, to change the mode from Class Power Limit to
Port Limit and vice versa. The power values per port that were configured
for the Port Limit mode are retained.
•
Maximum port limit allowed as a per-port numerical limit in mW (Port Limit
mode).
•
To generate a trap when a PD tries to consume too much and at what
percent of the maximum power this trap is generated.
The PoE-specific hardware automatically detects the PD class and its power limit
according to the class of the device connected to each specific port (Class Limit
mode).
If at any time during the connectivity an attached PD requires more power from the
switch than the configured allocation allows (no matter if the switch is in Class
Limit or Port Limit mode), the switch does the following:
•
Maintains the up/down status of the PoE port link
•
Turns off power delivery to the PoE port
•
Logs the reason for turning off power
•
Generates a trap to a remote log server
