Spanning tree commands
active region-configuration
Use active region-configuration to activate your MST region configuration.
Syntax
active 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.
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.
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
