8.3.4 Activating the Configuration of an MST Region

Context
Do as follows on the S9300 that needs to be added to the MST region.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
stp region-configuration
The MST region view is displayed.
Step 3 Run:
check region-configuration
The parameters of the MST region that have not taken effect are displayed.
Changing the values of parameters (especially the VLAN mapping table) of an MST region
causes the recalculation of spanning trees and the route flapping on a network. Therefore, it is
recommended that you run the check region-configuration command in the MST region view
before activating the configuration of the MST region to check whether the parameters of the
MST region are set correctly. After verifying that the parameters of the MST region are correct,
run the active region-configuration command to activate the configuration of the MST region.
Step 4 Run:
active region-configuration
The configuration of the MST region is activated.
The active region-configuration command activates the name, VLAN mapping table, and
MSTP revision level of the MST region.
It is recommended that you run the active region-configuration command after complete all
the configurations to reduce network flapping.
