The following is an example of the CLI commands:
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

spanning-tree guard root
Enables root guard on all the spanning
tree instances on that interface.
