Description
Use the check region-configuration command to view the configuration
information (including switch region name, revision level, and VLAN mapping
table) to be activated.
MSTP defines that the user must ensure the correct region configurations,
especially the VLAN mapping table configuration. The switches can be configured
in the same region only if their region names, VLAN mapping tables, and MSTP
revision levels are configured exactly the same. The switch may not be configured
in the expected region due to any slight deviation. You can use this command to
display the MST region configuration information to be activated to know to
which MST regions the switch belongs and check if the MST region configurations
are correct.
Related command: instance, region-name, revision-level, vlan-mapping
modulo, active region-configuration.
