MSTP Configuration on active region-configuration

Function

This command is used to activate the configuration of the Multiple Spanning Tree (MST) region manually. When the MST region is re-configured and you need to validate the configuration, run this command. After that, the configuration of the MST region is available.

CAUTION:

Activating the configuration of the MST region interrupts ongoing services. Therefore, run this command with caution.

Parameters

None

Modes

MST region mode, OSN 3500, OSN 2500

Operator level

Usage Guidelines

• Run the config command to enter global config mode, and then run the stp region-configuration command to enter MST region mode.
• When you configure the related parameters of the MST region, especially the mapping table for VLAN and examples, the topology may get unstable. To decrease the instability caused by the configuration, MSTP does not trigger recalculation of the spanning tree immediately, but activate the related parameters of the MST region or enable the MSTP protocol to validate the configuration.
• Any change of a parameter of the MST region may cause the recalculation of the topology. Run this command to make configuration take effect.
• By running this command, the configured parameters of the MST region are replaced by the current running parameters. MSTP recalculates the spanning tree.

Example

To activate the configuration of the MST region manually, do as follows:

huawei(stp-region-configuration)#active region-configuration             
  STP actives region configuration,it may take several minutes,are you sure to
active region configuration? [Y/N][N]y
  Command is being executed. Please wait: 100%

System Response

• The command execution duration varies depending on other configurations in the system. If the duration is long, the system displays the progress.
• The system does not display any message after the command is executed successfully.
