The Critical level is the highest priority level. Ports set to this level are
guaranteed power before any ports assigned to the other two priority
levels. Ports assigned to the other priority levels receive power only if all
the Critical ports are receiving power. Your most critical powered devices
should be assigned to this level. If there is not enough power to support all
the ports set to the Critical priority level, power distribution is based on port
number, in ascending order.
The High level is the second highest level. Ports set to this level receive
power only if all the ports set to the Critical level are already receiving
power. If there is not enough power to support all of the ports set to the
High priority level, power is provided to the ports based on port number, in
ascending order.
The lowest priority level is Low. This is the default setting. Ports set to this
level only receive power if all the ports assigned to the other two levels are
already receiving power. As with the other levels, if there is not enough
power to support all of the ports set to the Low priority level, power is
provided to the ports based on port number, in ascending order.
Power allocation is dynamic. Ports supplying power to powered devices
may cease power transmission if the switch’s power budget has reached
maximum usage and new powered devices, connected to ports with a
higher priority, become active.
The POWERLIMIT parameter in this command sets the maximum amount
of power a powered device can draw from the port. The value is set in
milliwatts. The default is 15400 mW (15.4 W).
Examples
This command disables PoE on ports 4 and 5:
set poe port=4-5 poefunction=disable
This command sets the priority on ports 6 and 11 to high:
set poe port=6,11 priority=high
This commands sets the maximum power on port 14 to 12,500 mW:
set poe port=14 powerlimit=12500
