Intel AXXSW1GB manual Defining Multiple STP Instance Settings

Defining Multiple STP Instance Settings

Multiple STP 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 Multiple STP, 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 Multiple STP instance settings using the Instance Settings Page.

To define the Instance settings:

1.Click Layer 2 > Multiple STP > Instance Settings. The Instance Settings Page opens:
