Whether you're showing up on the job fresh from a Cisco certification with no job experience or you've been in the field for awhile this book has something to offer that you're not going to find elsewhere. In a nutshell, it is the networking book to help you get your job done. The book focuses on teaching what you need to know on the job and not just information to to pass a certification exam. It helps turn on light bulbs that you may not get when reading cisco Press books. It explains thing with simple examples and uses fun analogies. I have to say this
is the first networking book that I have read that I just didn't want to put down. (think spy thriller or mystery novel) If you are in the networking field, buy this book and read it cover to cover like I did. (or virtual cover to cover via Kindle in my case) Absolutely wonderful book!
One of the best book for sure, a very true focus between CCNA and CCNP. It will be the excellent book after you finished CCNA.
However,there are something to be desired on some topics. For example, the QOS chapter is clearly confused reader on queuing topic, CBWFQ and LLQ. No information about maximum priority rate and after guarantee certain amount, how difference between those 2 queuing on the left sources.
To be honest, this is the shortcoming of this book, it covered almost all the topics in network area, however, some of them are not deep enough or I can say the topic itself is too complicated to explain.
Again, this is definitely one of the best book in this market.
This is book is a must to get your basics in order once again. over a period of time you tend to forget the technologies that you used in pasd and are now not actively involved in them. This books helps you remember it. Going through the book is like getting those light bulbs in your mind go On. The most common reaction for me when reading this book was " aahh...I read it...Now I remember it." Happy Recollecting.
Network Warrior is one of those books that every IT pro should have. I actually ordered an additional copy of this book to keep at home as when I first received it I was taking it to and from the office.
I recommend it to anyone who is not only getting started in networking, but also for anyone who is an IT "jack of all trades," as it's impossible to remember all the little command nuances or the real world best practices of a technology if you don't use it every day.
When I need to do something networking-related that I haven't done in a while, I usually look in this book first. For example, I know tomorrow I'm going to be setting up an old Catalyst 3550 as a multilayer switch for a project. I haven't set up an SVI in at least a year. I know I need to put a "no switchport" command in somewhere. I know I could search online for it, but then there's always Network Warrior!
I used the first edition all of the time at work. Very helpful guide. This edition 2, same information as the first with a lot of new content. The VoIP stuff is good, nice intro to CME, you're not going to be able to troubleshoot Call Manager or anything, but it nice for the voice gateways. The ASA stuff is good, though I wish they would have set it up like the rest of the book where their showing CatOS, IOS and NEXUS. I still deal with customers who have PIX and some have ASAs. Most things are very similar but not everything. The MPLS entry is a waste of only 6 pages. The wireless is a bit of a waste too. It good if you are dealing with autonomous AP's or single Cisco AP's at the house. Otherwise you should know this from the CCNA. The High availability stuff (HSRP) is good.
I have relied on the first edition and I trust the second will be there too. As many topics were expanded upon and troubleshooting methods were added. This is definatly my field manual of choice.
If you walk into any networking geeks secret lair and scan your eyes along the endless horizon of nerdomenclature, you'll undoubtedly find Gary Donahue's original Networking Warrior somewhere pressed up against a vast collection of Cisco Press, Sybex, O'Reilly and occasional Max Brooks literature. From the beginning Gary Donahue's masterpiece has been widely accepted as thee' post CCNA book for every Cisco guy since 2007. As the unofficial go to manual for everything untaught on the CCNA a Cisco network engineer needs to know, Gary has taken his place among the elite masters Cisco authors such as Jeff Doyle, Wendell Odom, Jeremy Cioara and David Hucaby just to name a few.
Networking Warrior Second Edition has updated it's core example technologies to reflect the ever evolving industry we as network engineers work with on a daily bassis. Giving us operational examples on Cisco new cutting edge equipment including the Cisco ASA Firewalls 8.0+ IOS, 3750 & 6500 switches and even the super-cool new Nexis product line emerging from the dark shadows intending to over the world one packet at a time. Gary takes his time at the end of each applicable chapter to explain the differences of implementing each technology though the IOS, CatIOS and new Nexus NX-OS giving clear examples that are easy to follow doubling this book as an excellent field manual alongside the extremely popular Portable Command Guides published by Cisco Press.
What make book unique from most publishing's is Gary's sparkling humor scatted throughout his writings. One moment he will be explaining the technical aspect of the subject, the next he'll be making a metaphor funny enough to make your Spouse look over your shoulder and ask "whats so funny?", and after the fourth or fifth time may or may not be a good thing. Even though this book flows very well, it is not without it's fresh off the print edition errors. There are areas in the text where examples have not been updated to reflect the new books updated example equipment, other areas have diagram abnormalities, but we're not here to judge Gary's wife's editorial skills. I'm sure it's hared enough just to put up with him (joking of course).
Garry mentions and gives a great amount credit to his wife as being his front line editor though the many months involved in writing this book.
Networking Warrior spans an impressive 41 chapters covering a slue of topics. Just holding this book in your hands and thumbing though the chapter indexes gives you an idea of just how much Gary covers. I'd like to say this book is an excellent cover to cover read, and in some major blocks it is, but there are some section that no matter how supper-geek status you give yourself you'll just find yourself over inundated with information or lack of understanding, especially if you're fresh off the CCNA boat. The clear cut and skinny on this book is: If you're a CCNA looking for the next step, or a networking nut wanting to freshen up your knowledge of Cisco solutions you're in for a treat. Because Gary Donahue has everything but gift wrapped you the next book to fill that empty slot on your bookshelf. If is, if it ever gets off your desk.
Upshot: And you may find yourself...in a machine room or data center. You will need this book. Pros: If you just passed your CCNA exam, or have started working with enterprise level Cisco kit, there's a lot here for you. Cons: If you DON'T work with Cisco kit, why are you here?
For anyone not acquainted with data-centers & network operations, this book shows you how the other hardware half lives. When the author says `you should have passed the CCNA' he's very serious. There are NO EXPLANATIONS of basic Cisco terms. If you are not versed in TCP/IP and SOME Cisco kit, you will be spending a LOT of time in Google. And probably asking yourself why you bought this book.
Those cautions aside, there are gems of `best practices' for non Cisco or smaller network techs here: Amid the Cisco jargon you will find practical advice even for your small business or SOHO LAN, like in Ch. 27 `Basic Firewall Theory', or Chapter 29 on different flavors of 802.11x WiFi and how to secure it. The author even introduces IPv6, with one of the most straightforward explanations I've read yet.
But what really makes this book worth it are the backstories & practical advice from a veteran to new engineers on how to handle failure scenarios as well as the politics involved in maintaining large networks.
In fact, everything from Chapter 39 (`Failure'), Chapter 40 (`GAD's Maxims') to Chapter 41 (`Avoiding Frustration') would be welcome in any IT, infosec or dev reference.
In short, I would somewhat recommend this book for non-CCNA folks interested in Network Engineering or Infrastructure. But I would highly recommend Network Warrior for the audience for which it was intended.
Disclosure: I received the eBook download from O'Reilly for review purposes. I'm not a CCNA but have been around.
