78 Spanning Tree Concepts ELS100-24TXG
Spanning Tree Protocol in a Network
Figure B-1 illustrates the use of three ELS100-24TXG switches to
establish an effectiv e Spanning Tree config uration. Switches A, B an d 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 bec o mes active, thereby es t ablishing a path
between A and B through switch C. Additionally, if the connection
between B and C goes down, the link betwee n A an d C bec o me s ac tiv e,
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 th e p ar am ete rs a nd 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.
