Spanning Tree Configuration

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

Algorithm. The Spanning Tree Algorithm (STA) in the DES-5024 allows you to create

alternative paths (using multiple switches or bridges) in your network. These backup

paths are idle until the DES-5024 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. See

Table 7: User Selective STA Parameters.

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

the Bridge Identifier for each DES-5024, then sets the Root Bridge and the Designated

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

The Spanning Tree Configuration menu, displayed in Figure 34, allows you to enable or

disable STA, set bridge priority and other configurations.
