Todd Lammle's CCNA/CCENT IOS Commands Survival Guide 2nd Edition

Very good compilation of the commands and concepts for CCENT/CCNA IOS. It's a more condensed version of Lammle's CCNA Routing and Switching Deluxe Study Guide (CCNA Routing and Switching Deluxe Study Guide: Exams 100-101, 200-101, and 200-120 Hardcover - December 23, 2013) and Lammle's CCNA R&S DSG Review Guide (CCNA Routing and Switching Review Guide: Exams 100-101, 200-101, and 200-120 Paperback - January 13, 2014). Not a bad idea to have all 3 (I do) and use the IOS Commands as more of a quick desk/study reference.

This book is a great reference for preparing for the CCENT/CCNA, its short and to the point with the commands. I brought this book for $13 I don't understand why some re-sellers are price gouging by selling it over $300. With that being said, if you are able to get a copy it will be a great reference tool.

It is exactly as it describes it is a desk reference for us Command line dummies!

Solid companion to have at your side while working on labs and just need to quickly get to the information you need. I recommend purchasing this author (Todd Lammle's) CCNA R&S Study Guide as your main source of information, and have this by your side while you hammer out labs as practice. Also a great book to bookmark and keep around to quickly cram in a few minutes of studying here and there.

This is a great book to pair up with your studies. Todd covers a lot of good commands and briefly discusses some concepts as well. I wouldn't recommend this book be your only source of information though. But, like I said, pairing it with your other study guides will probably work great.

Excellent book for someone who uses Cisco devices often. Saves you from having to remember certain commands that are not used frequently and from having to use Google. However it expected that you have a certain level of knowledge of Cisco devices before hand with some of the explanations that it uses.

This book is great and puts everything you need to know into one book. It makes it easier to study the command lines while not having to go through the bigger book.

Lammle offers more than a listing of commands available for functions needed. He describes the logic behind the commands giving examples of why or why not command sequences are used for specific cases. His approach is easily understandable, well-organized and compact. It's a book best kept nearby for any network engineer or administrator.
