Bridging

Designated Port

Displays the network address portion of the Port ID (which includes a manageable Priority component) of the port believed to be the Designated Port for the LAN associated with this port.

The Designated Port ID, along with the Designated Bridge and Port Identifier parameters for the port, is used to determine whether this port should be the Designated Port for the LAN to which it is attached. Management also uses it to determine the Bridged LAN topology.

Topology

This indicates how many times the bridge’s Topology Change flag has been changed since the 9H42x-xx module was last powered-up or initialized. The Topology Change flag increments each time a bridge enters or leaves the network, or when the Root Bridge ID changes.

Changing Bridge Spanning Tree Parameters

The Bridge Spanning Tree window allows you to update the following parameters for the 9H42x-xx module. When you have finished making changes to

the following individual parameters, you must click on at the bottom of the Spanning Tree window to write the changes to the device.

NOTE

Any values you set at the bridge will cause a Topology Change flag to be issued in the next Configuration BPDUs it transmits. This will cause the bridged network to immediately recalculate Spanning Tree and change topology accordingly.

Changing Bridge Priority

To change the part of the bridge address that contains the identifier used in the Spanning Tree Algorithm for priority comparisons:

1.Highlight the Bridge Priority field.

2.Enter the new identifier, in hexadecimal format; the allowed range is 0-FFFF hexadecimal.

3.Click on .

The selected Bridge Priority will be applied to the bridge (a lower number indicates a higher priority in the root selection process).
