Parameter
bridge-priority: Specifies the priority of a switch, ranging from 0 to 61440.
The values are not consecutive integers. The step length is 4096. By default, the
value is 32768.
Description
Using the stp priority command, you can configure the bridge priority of the
switch. Using the
undo stp priority command, you can restore the default
bridge priority of the switch.
The priority value shall be a multiple of 4096, such as 0, 4096, 8192 etc. The
smaller value represents the higher priority. A switch with higher priority is more
likely to be a root bridge.

Description
Using the stp root primary command, you can configure the current switch as
the primary root of a spanning tree. Using the
undo stp root primary

You can designate a primary tree for the spanning tree without caring about the
priority configuration of the switch.
