active region-configuration
Syntax
active region-configuration
View
MST region view
Default level
2: System level
Parameters
None
Description
Use active region-configuration to activate your MST region configuration.
When you configure MST region–related parameters, MSTP launches a new spanning tree calculation process that may cause network topology instability. This is mostly likely to occur when you configure the VLAN-to-instance mapping table. The launch will only occur after you activate the MST region–related parameters by using active region-configuration command or enable MSTP by using the stp enable command.
Hewlett Packard Enterprise recommends that you use the check region-configuration command to determine whether the MST region configurations to be activated are correct. Run this command only when they are correct.
