Spanning tree configuration commands

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.
HP 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.
Related commands: instance, region-name, revision-level, vlan-mapping modulo, and check
region-configuration.
