Spanning tree commands active region-configuration Use active region-configuration to activate your MST region configuration. Syntax active region-configuration Views MST region view Predefined user roles network-admin Usage guidelines When you configure MST region 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 occurs after the MST region parameters are activated with the active region-configuration command or you enable the spanning tree feature with the stp global 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. system-view [Sysname] stp region-configuration [Sysname-mst-region] instance 1 vlan 2 [Sysname-mst-region] active region-configuration Related commands • check region-configuration • instance • region-name • revision-level • stp global enable • vlan-mapping modulo bpdu-drop any Use bpdu-drop any to enable BPDU drop on a port.
