Power over Ethernet Commands
The commands in this group control the power that can be delivered to attached
PoE devices through the switch ports.
The switch’s power management enables total switch power and individual port
power to be controlled within a configured power budget. Port power can be
automatically turned on and off for connected devices, and a per-port power priority
can be set so that the switch never exceeds its allocated power budget. When a
device is connected to a switch port, its power requirements are detected by the
switch before power is supplied. If the power required by a device exceeds the
power budget of the port or the whole switch, power is not supplied.
power mainpower maximum allocation
This command defines a power budget for the switch (i.e., the power available to all
switch ports). Use the no form to restore the default setting.
