Spanning Tree Algorithm (STA)

The Spanning Tree Algorithm can be used to detect and disable network

loops, and to provide backup links between switches, bridges or routers.

This allows the switch to interact with other bridging devices (that is,

STA-compliant switch, bridge or router) in your network to ensure that

only one route exists between any two stations on the network. For a more

detailed description of how to use this algorithm, refer to “Spanning Tree

Algorithm” on page 4-2.

Spanning Tree Information

The Spanning Tree Information screen displays a summary of the STA

information for the overall bridge or for a specific port. To make any

changes to the parameters for the Spanning Tree, use the Spanning Tree

Configuration menu.
