Defining MSTP Instance Settings

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.
Network administrators can define the MSTP instance settings using the MSTP
Instance Settings Page
Note: To ensure that the MSTI maintains connectivity across the network, you must
configure a related set of bridges with the same MSTI settings.
Command Attributes
• Instance ID — Specifies the VLAN group to which the interface is assigned.
• Included VLAN — Maps the selected VLANs to the selected instance. Each VLAN

The field range is 0-61440.

cost to the instance ID.
