1.1 MSTP Configuration Commands
1.1.1 active region-configuration
Syntax
active region-configuration
View
MST region view
Parameter
None
Description
Use the active region-configuration command to activate the settings of an MST
(multiple spanning tree) region.
Configuring MST region-related parameters (especially the VLAN mapping table) result
in spanning trees being regenerated. To reduce network topology jitter caused by the
configuration, MSTP (multiple spanning tree protocol) does not regenerate spanning
trees immediately after the configuration; it does this only after you activate the new
MST region-related settings or enable MSTP, and then the new settings can really take
effect.
This command causes the switch to operate with the new MST region-related settings
you configured and spanning trees to be regenerated.
Related command: instance, region-name, revision-level, vlan-mapping modulo,
and check region-configuration.

# Activate the MST region-related settings.
