power-priority
To configure Cisco StackPower power-priority values for a switch in a power stack and for its high-priority
and low-priority PoE ports, use the
power-priority command in switch stack-power configuration mode. To
return to the default setting, use the no form of the command.
power-priority { high value | low value | switch value }
no power-priority { high| low| switch }
Syntax Description
Sets the power priority for the ports configured as high-priority ports. The range is 1
to 27, with 1 as the highest priority. The
high value must be lower than the value set
for the low-priority ports and higher than the value set for the switch.
high value
Sets the power priority for the ports configured as low-priority ports. The range is 1
to 27. The
low value must be higher than the value set for the high-priority ports and
the value set for the switch.
low value
Sets the power priority for the switch. The range is 1 to 27. The
switch
value must be
lower than the values set for the low and high-priority ports.
switch value
Command Default
If no values are configured, the power stack randomly determines a default priority.
The default ranges are 1 to 9 for switches, 10 to 18 for high-priority ports, 19 to 27 for low-priority ports.
On non-PoE switches, the high and low values (for port priority) have no effect.

Modification Release

Usage Guidelines
To access switch stack-power configuration mode, enter the stack-power switch switch-number global
configuration command.
Cisco StackPower power-priority values determine the order for shutting down switches and ports when power
is lost and load shedding must occur. Priority values are from 1 to 27; the highest numbers are shut down first.
We recommend that you configure different priority values for each switch and for its high priority ports and
low priority ports to limit the number of devices shut down at one time during a loss of power. If you try to
configure the same priority value on different switches in a power stack, the configuration is allowed, but you
receive a warning message.
