As specified in the MSTP protocol, the configurations of MST regions must be right, especially the 

VLAN-to-instance mapping table. MSTP-enabled switches are in the same region only when they have 

the same format selector (a 802.1s-defined protocol selector, which is 0 by default and cannot be 

configured), region name, VLAN-to-instance mapping table, and revision level. A switch cannot be in 

the expected region if any of the four MST region-related parameters mentioned above are not 

consistent with those of other switches in the region. 

The 3Com switches 5500-EI support only the MST region name, VLAN-to-instance mapping table, and 

revision level. Switches which have the settings of these parameters the same are assigned to the 

same MST region.  

This command is used to display the configuration information of inactivated MST regions. You can use 

this command to find the MST region the switch currently belongs to or check to see whether or not the 

MST region-related configuration is correct. 

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

region-configuration.
