Cisco IOS in a Nutshell: A Desktop Quick Reference for IOS on IP Networks (In a Nutshell (O'Reilly))

I wouldn't use this as your lone prep for your CCNA, although it certainly would help, and you'll find yourself using it once you're actually on the job. It does prodvide a good reference to all the commands you're going to use on a daily basis and then some. Also, another thing I like about it is, you'll know where to find the command. Unlike some other books I've bought regarding this, the commands, and subcommands, are well explained, with enough depth that you'll understand the command, and when you would use it.

This book is very dated -- it doesn't even cover the zone-based firewall that my IOS 12.04 router has. However, there's not much else out there, so what are you going to do? A large part of the book is dedicated to a reference section, which seems a little redundant considering that any reasonable person is just going to google when they need to know command syntax. The value of this book is the how-to part, which will tell you how to configure a variety of services on your router. The biggest drawback is the lack of discussion of the newer firewall technologies.

I use this to administer OJT to the newbie and the intern where I work. It gives you enough to do it, without being excessively detailed. It does assume you have a certain level of understanding of the Cisco gear and OS, though. I love this thing. Put it on a tablet or laptop and keep it with you if you deal with Cisco on any sort of regular basis. It is that good.

If you're like me, and can skim through a manual book and get the information into your head, then this is for you. It's a great refresher, also. I really enjoy this book since I don't have to read a paragraph to get the information I need on one thing.

This is a good reference book, but don't count on it to teach you how to set up a Cisco device or any networking. Even though it is fairly current, I have found a few differences between it and IOS 12.4 T.

Good reference for the regular Joe who is not a walk encyclopedia of Cisco IOS!

Decent for the subject.

Thanks nice book.

Very good service. Recommended.

Was für das Buch spricht, ist der lockere, leicht verständliche Stil und die wirklich hervorragenden Tips rund um das Router- und Switch-Betriebssystem von Cisco. Kaum ein Anwendungsfall bleibt außen vor, die Beispiele sind aus der Praxis für den Praktiker ausgewählt. Mit etlichen Tips kann man sein eigenes Netzwerkumfeld schnell ein wenig optimieren. Der Index ist sehr gut aufgebaut und hilft, schnell zum gesuchten Thema zu gelangen.Leider ist das Buch nicht sehr aktuell und wird meines Wissens auch nicht mehr aktualisiert. Da bleiben etliche Features der modernen IOS-Varianten außen vor und manches muss man auch erst in die neueren Dialekte übertragen. Nexus OS wird gar nicht behandelt, da es zur Drucklegung noch nicht am Markt war.Als Tippgeber für Cisco-Einsteiger und als Denkhilfe für mal etwas krummere Lösungswege ist das Buch aber durchaus noch zu empfehlen.
