Defining MSTP Instance to VLAN
MSTP maps VLANs into STP instances. Packets assigned to various VLANs are
transmitted along different paths within
Multiple Spanning Tree Regions
(MST
Regions). Regions are one or more Multiple Spanning Tree bridges by which
frames can be transmitted. In configuring MSTP, the MST region to which the
device belongs is defined. A configuration consists of the name, revision, and
region to which the device belongs.
The VLAN page enables mapping VLANs to MSTP Instances.
