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 mostly likely to occur when you configure the VLAN-to-instance mapping table. The launch will only occur after you activate the MST region–related parameters by using active region-configuration command or enable MSTP by using the stp enable command.

Hewlett Packard Enterprise 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.
