Summary

As soon as you have checked for hardware issues with a switch, it is important that you thoroughly check your switch configuration with the show commands discussed today. Sometimes other administrators control neighboring switches. CDP allows you to peek at some of their configuration information and see if the issue is their problem or yours. When everything looks good on your end, do not forget the powers of CDP. You can further review the topics from today on pages 129–172 and 315–342 of CCNA Flash Cards and Exam Practice Pack (CCENT Exam 640-822 and CCNA Exams 640-816 and 640-802), Third Edition.
