Spanning Tree Switch Configuration
The Spanning Tree Switch Configuration panel, shown in Figure 54, enables you
to configure Spanning Tree either globally for the DES-5600 or locally on a port
by port level. 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.
Spanning Tree Switch Configuration
Configures global Spanning Tree and bridge priority on the DES-5600.
