The device priority is involved in spanning tree calculation. The device priority is set on a per-MSTI 

basis. An MSTP-enabled device can have different priorities in different MSTIs.  

If you do not provide instance instance-id, your configuration will take effect in the CIST instance only.  

# Set the device priority in MSTI 1 to 4096.  

<Sysname> system-view 

[Sysname] stp instance 1 priority 4096

None 

Use the stp region-configuration command to enter MST region view.  

Use the undo stp region-configuration command to restore the default MST region configurations.  

By default, the default settings are used for all the three MST region parameters. Namely, the device’s 

MST region name is the device’s MAC address, all VLANs are mapped to the CIST, and the MSTP 

revision level is 0.  

After you enter MST region view, you can configure the parameters related to the MST region, including 

the region name, VLAN-to-MSTI mappings and revision level.  

# Enter MST region view.
