MSTP Configuration Commands

active region-configuration

Syntax
active region-configuration
View
MST region view
Default Level
2: System level
Parameters
None
Description
Use the active region-configuration command to activate your MST region configuration.
Note that:
The configuration of MST region–related parameters, especially the VLAN-to-instance mapping
table, will cause MSTP to launch a new spanning tree calculation process, which may result in
network topology instability. To reduce the possibility of topology instability caused by configuration,
MSTP will not immediately launch a new spanning tree calculation process when processing MST
region–related configurations; instead, such configurations will take effect only after you activate
the MST region–related parameters using this command, or enable MSTP using the stp enable
command in the case that MSTP is not enabled.
Before running this command, you are recommended to use the check region-configuration
command to check whether the MST region pre-configurations are correct. You should run this
command only if the result returns positive.
