Enter a new value between zero and 255.

Select Save and press Enter.

Spanning Tree Configuration

The Spanning Tree Configuration panel is used to configure the Spanning Tree Algorithm.

The Spanning Tree Algorithm (STA) in the DES-3224 allows you to create alternative paths

(using multiple switches or bridges) in your network. These backup paths are idle until the

DES-3224 determines that a problem has developed in the primary path. If the primary path

breaks down STA will activate the backup path. STA is very complicated and you should

understand it well before changing the default settings.

STA Operation Levels

STA operates on the bridge level and the port level. On the bridge level, STA calculates the

Bridge Identifier for each DES-3224 then sets the Root Bridge and the Designated Bridges.

On the port level, STA sets the Root Port and Designated Ports.

Spanning Tree Configuration Menu

The Spanning Tree Configuration menu, displayed in Figure 24, allows you to enable or

disable STA, set bridge priority and other configurations.
