Description
Use the region-level command to configure the MSTP revision level.
Use the undo region-level command to restore the default MSTP revision level.
By default, the MSTP revision level is 0.
Note that:
z The MSTP revision level, the MST region name and the VLAN-to-instance mapping table of a
device jointly determine the MST region to which the device belongs. When the MST region name
and VLAN-to-instance mapping table are both the same for two MST regions, you can still tell them
apart by their MSTP revision levels.
z After configuring this command, you need to run the active region-configuration command to
activate the configured MST region level.
Related commands: instance, region-name, vlan-mapping modulo, display stp
region-configuration, check region-configuration, active region-configuration.
