Spanning Tree Configuration Menu
The Spanning Tree Configuration Menu, shown in Figure 23, enables you to
configure Spanning Tree globally on the DES-5600 or on a port by port basis. The
Spanning Tree Algorithm (STA) in the DES-5600 enables you to create
alternative paths (using multiple switches or bridges) in your network. These
backup paths are idle until the DES-5600 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-5600, then sets the Root Bridge and
the Designated Bridges. On the port level, STA sets the Root Port and Designated
Ports.
