1.1.1 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.
