Parameters
instance-id: MSTI ID ranging from 0 to 16. The value of 0 refers to the CIST.
priority: Switch priority to be set. This argument ranges from 0 to 61,440 and must be a multiple of 4,096
(such as 0, 4,096, and 8,192). There are totally 16 available switch priorities.
Description
Use the stp priority command to set the priority of the switch in the specified MSTI.
Use the undo stp priority command to restore the switch priority to the default priority in the specified
MSTI.
The default priority of a switch is 32,768.
The priorities of switches are used for spanning tree calculation. Switch priorities are spanning
tree-specific. That is, you can set different priorities for the same switch in different MSTIs.
If you do not specify the instance-id argument, the two commands apply to only the CIST.

# Set the bridge priority of the switch in MSTI 1 to 4,096.
