Troubleshooting Ethernet Networks

In this Study Guide you will learn how Ethernet and associated IEEE 802 standards really work -- and what causes them not to work at times. An assumption is made that you have already read many simple descriptions of Ethernet behavior. The goal of this tutorial is to introduce you to new ways of thinking about Ethernet that will help you troubleshoot common problems found on 10-Mbps, 100-Mbps, and 1000-Mbps ("Gigabit") Ethernet networks. This paper will also take you "beyond Cisco certification" and into the use of protocol analyzers to view certain behaviors.
