Description
Use the check region-configuration command to display the MST region-related configuration which
is being modified currently, including region name, revision level, and VLAN-to-MSTI mapping table.
As specified in the MSTP protocol, the configurations of MST regions must be right, especially the
VLAN-to-MSTI 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-MSTI 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 another switch in the region.
The H3C series support only the MST region name, VLAN-to-MSTI mapping table, and revision level.
Switches with the settings of these parameters being 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.
