Summary

This chapter presented an introduction to troubleshooting, a review of standards and protocols, industry models, troubleshooting methods, baselining, and documentation techniques. The chapter covered the OSI model and included information on how an understanding of that model can aid you in the troubleshooting process. The DoD TCP/IP suite was also covered and compared to the OSI model. The Trouble Ticket offered you an opportunity to apply the Cisco troubleshooting method and other techniques you learned in this chapter. Now that you have reviewed and studied a systematic approach to troubleshooting, you should determine whether you really have the right tools for the job.
