Spanning Tree Protocol in a Network

Figure B-1 illustrates the use of three ELS100-24TXG switches to
establish an effective Spanning Tree configuration. Switches A, B and C
are connected together in a redundant topology (more than one path
between two points). If the connection between A and B goes down, the
link between A and C becomes active, thereby establishing a path
between A and B through switch C. Additionally, if the connection
between B and C goes down, the link between A and C becomes active,
establishing a path between B and C through switch A.

Spanning Tree Protocol Parameters

Several configuration parameters control the operation of the Spanning
Tree Protocol. Table B-1 describes the parameters and lists the ELS100-
24TXG switch default settings for each parameter.

You can cause serious network performance degradation
if you do not fully understand Spanning Tree concepts.
Be sure to consult personnel experienced with this pro-
cess prior to configuring Spanning Tree parameters.
