Use the check region-configuration command to view all the configuration information of the MST 

region, including the region name, VLAN-to-MSTI mapping and revision level settings.  

Be sure that your MST region configurations are correct, especially the VLAN-to-MSTI mapping table. 

As defined in the MSTP protocol, MSTP-enabled devices are in the same MST region only when they 

have the same format selector (protocol format selector defined in 802.1s, which is 0 by default and 

unconfigurable), region name, VLAN-to-MSTI mapping table, and MSTP revision level settings. A 

device will be in a different region if it is different in any of these four settings.  

You can view all the MST region–related configuration information by using this command and 

determine the MST region the device is currently in, or check whether the MST region configuration is 

correct.  

Related commands: instance,  region-name,  revision-level,  vlan-mapping modulo,  active 

region-configuration.
