Use
active region-configuration
to activate your MST region configuration.
Syntax

region-configuration
Views

Default command level
2: System level
Usage guidelines
When you configure MST region–related parameters, MSTP launches a new spanning tree
calculation process that might cause network topology instability. This is most likely to occur when
you configure the VLAN-to-instance mapping table. The launch will occur only after you activate the
MST region–related parameters by using the
active region-configuration
command or enable the
spanning tree feature by using the
stp enable
command.
H3C 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.
Examples
# Map VLAN 2 to MSTI 1 and manually activate the MST region configuration.
<Sysname> system-view
[Sysname] stp region-configuration
[Sysname-mst-region] instance 1 vlan 2
[Sysname-mst-region] active region-configuration
