To configure 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 switch stack-power configuration command. 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 | system}
This command is available only on Catalyst 3750-X switch stacks running the IP base or IP services
feature set.
high value
Sets the power priority for the ports configured as high-priority ports. The
range is from 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.
low value
Sets the power priority for the ports configured as low-priority ports. The
range is from 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.
switch value
Sets the power priority for the switch. The range is from 1 to 27. The switch
value must be lower than the values set for the low and high-priority ports.
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.
Switch stack-power configuration
Release
Modification
12.2(53)SE2
This command was introduced.
To access switch stack-power configuration mode, enter the stack-power switch switch-number global
configuration command.
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.
