Defining Mstp Instance Settings - Cisco Linksys SFE1000P Reference Manual

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 MSTP Instances settings using the MSTP Instance Settings Page.
The MSTP Instance Settings Page contains the following fields:
• Instance ID — Defines the VLAN group to which the interface is assigned.
• Included VLAN — Maps the selected VLAN to the selected instance. Each VLAN belongs to
one instance.
• Bridge Priority — Specifies the selected spanning tree instance device priority. The field
range is 0-61440
• Designated Root Bridge ID — Indicates the ID of the bridge with the lowest path cost to the
instance ID.
• Root Port — Indicates the selected instance's root port.
• Root Path Cost — Indicates the selected instance's path cost.
• Bridge ID — Indicates the bridge ID of the selected instance.
• Remaining Hops — Indicates the number of hops remaining to the next destination.
