82 Spanning Tree Concepts ELS100-24TXM
Spanning Tree Protocol in a Network
Figure B-1 illustrates the use of three ELS100-24TXM 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.
