Description 
Use the stp priority command to set the priority of the switch in the specified spanning 
tree instance. 
Use the undo stp priority command to restore the switch to the default priority in the 
specified spanning tree instance. 
The default priority of a switch is 32,768. 
The priorities of switches are used for spanning tree generation. Switch priorities are 
spanning tree-specific. That is, you can set different priorities for the same switch in 
different spanning tree instances. 
If you do not specify the instance-id argument, the two commands apply to the CIST. 
Example 
# Set the priority of the switch in spanning tree instance 1 to 4,096. 
<Quidway> system-view  
System View: return to User View with Ctrl+Z.
