MSTP Configuration Commands
active region-configuration
Syntax
active region-configuration
View
MST region view
Parameters
None
Description
Use the active region-configuration command to activate the settings of a multiple spanning tree
(MST) region.
Configuring MST region-related parameters (especially the VLAN-to-MSTI mapping table) is probable
to result in network topology jitter. To reduce network topology jitter caused by the configuration,
multiple spanning tree protocol (MSTP) does not recalculate 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.
When you carry out this command, MSTP will replace the currently running MST region–related
parameters with the parameters you have just configured and will perform spanning tree recalculation.
Related commands: instance, region-name, revision-level, vlan-mapping modulo, check
region-configuration.
Examples
