This module introduces the fundamentals of Spanning Tree Protocol (STP)
operation in a switched network. The root bridge will be explained as well as
how it and its backup are elected. Features for enhancing the performance of
STP will be covered, namely PortFast, UplinkFast and BackboneFast. You will
discover how EtherChannel is configured and how it interoperates with STP. The
module also provides guidelines on improving STP resiliency when network faults
occur.
