request. This value is generated by the switch to initiate a fabric
reconfiguration. This value cannot be assigned.

0x3 - 0xFE

Priority value range. Choose a value in this range to indicate priority.
Higher numbers mean lower priority.

Switch is not capable of acting as a principal switch. This is a
user-defined value. Use --enable with a new priority to revert to this
condition.

-force|-f

Forces a fabric rebuild. This option is required when enabling principal switch
mode. This option is not valid with the --disable command.

disable

Disables principal switch selection. This command resets the priority to the
default value 0xFE.

[-f ] mode

Sets the principal switch mode. Specify 1 to enable principal switch mode.
Specify 0 to disable principal switch mode. Optionally use the -f operand to
force a fabric rebuild. Mode changes take effect when the fabric rebuilds.
This operand is optional.
