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 an MST
(multiple spanning tree) region.
Configuring MST region-related parameters (especially the VLAN mapping table)
results in spanning trees being regenerated. To reduce network topology jitter caused
by such configurations, 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.
