Cisco Internetwork Troubleshooting Course Companion Book

The authors of CIT: Cisco Internetwork Troubleshooting know how to find and squash bugs in complicated systems. Here, their bug-hunting environment happens to be Cisco Systems routers and the networks on which they operate, but the lessons you'll learn from Thomas, Newcomb, and Mason will serve you well beyond Cisco troubleshooting. Their explanations of Internetworking technologies are so precise and so patiently explained that a newcomer to Internet infrastructure could do a lot worse than to use this book as his or her introductory text. The authors progress from basic troubleshooting concepts (divide and isolate, essentially), through the use of fault-finding tools (both hardware and software), and on through the essential troubleshooting commands that are built into Cisco's Internetworking Operating System (IOS) and other operating environments. Sections on troubleshooting particular kinds of network links--local area networks (LANs) and wide area networks (WANs) of various flavours--take a common tack. Each such section explains how a given connectivity technology (frame relay, X.25, or whatever) works in broad terms, then shows how various diagnostics work with the connectivity scheme. Readers get "enter this, get that" listings, plus commentary on those listings. Similar coverage goes to network protocols. --David Wall, amazon.com Topics covered: Finding and fixing trouble in Internetworks that run on Cisco equipment. Specific commands and strategies for repairing LAN and WAN connectivity, as well as for protocols that carry information over those networks, appear here. Routing protocols, Cisco support resources, and everything else proscribed in the Cisco documentation of the Cisco Internetwork Troubleshooting exam (640-440) gets attention here.Read More
