Using Spanning Tree Setup and Monitoring
Spanning trees are used to prevent loops from forming in your
network. The spanning tree algorithm creates a single path through
the network by ensuring that if more than one path exists between
two parts of a network, only one of these paths is used, while the
others are blocked.
* Note: You should have a good understanding of the spanning
tree protocol (STP) before attempting to configure these
parameters. Because of the number of “bridges” present
in a switched networking environment, STP structures
can become extremely complex. Refer to "Spanning Tree
Modes" in Chapter 1.
Managing
Spanning Tree
You can manage spanning trees using either the web agent or the
CLI.
