Configuring Multiple Spanning Tree

MSTP operation maps VLANs into STP instances. Multiple Spanning Tree provides differing load balancing
scenario. For example, while port A is blocked in one STP instance, the same port is placed in the Forwarding
State in another STP instance.
In addition, packets assigned to various VLANs are transmitted along different paths within Multiple Spanning
Trees Regions (MST Regions). Regions are one or more Multiple Spanning Tree bridges by which frames can be
transmitted. To open the MSTP Settings page, click Switch → Spanning Tree → MSTP Settings in the tree
view.
