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 most likely to occur when you configure the
VLAN-to-instance mapping table. The launch occurs only after the MST region–related parameters are
activated with the
active region-configuration
command, or you enable the spanning tree feature with
the
stp enable
command.
H3C recommends you to 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.
