Advanced Configuration

Spanning Tree > MSTP Instance Settings

MSTP operation maps VLANs into STP instances. 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. In configuring MST, the MST region to which the device belongs is defined. A configuration consists of the name, revision, and region to which the device belongs.

Spanning Tree > MSTP Instance Settings

Network Administrators can define MSTP Instances settings using the MSTP Instance Settings screen.

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 0–61,440.

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.

RemainingHops  Indicatesthenumberofhopsremaining to the next destination.

Spanning Tree > MSTP Interface Settings

Network Administrators can assign MSTP Interface settings using the MSTP Interface Settings screen.

Spanning Tree > MSTP Interface Settings

The MSTP Interface Settings screen contains the following fields:

Instance ID  Lists the MSTP instances configured on the device. Possible field range is 0–15.

Interface  Displays the interface for which the MSTP settings are displayed. The possible field values are:

•• Port  Specifies the port for which the MSTP settings are displayed.

•• LAG  Specifies the LAG for which the MSTP settings are displayed.

Port State  Indicates whether the port is enabled for the specific instance.

Type  Indicates if the port is a point-to-point port, or a port connected to a hub. The possible field values are:

•• Boundary Port  Indicates the port is a boundary port. A Boundary port attaches MST bridges to LAN in an outlying region. If the port is a boundary port, it also indicates whether the device on the other side of the link is working in RSTP or STP mode.

•• Master Port  Indicates the port is a master port. A Master port provides connectivity from a MSTP region to the outlying CIST root.

•• Internal  Indicates the port is an internal port.

Role  Indicates the port role assigned by the STP algorithm in order to provide to STP paths. The possible field values are:

•• Root  Provides the lowest cost path to forward packets to root device.

•• Designated  Indicates the port or LAG via which the designated device is attached to the LAN.
