Product Details
|
The book goes heavy on prose, enabling you to slowly absorb the truth about complex systems as the author lays a foundation of knowledge and then builds upon it. Conceptual diagrams help drive home relationships among network devices, though the blueprints in the center of the book suffer from being split down the middle by the book's binding--foldouts would have been far better. This is a superb book, though, one of the best around on internetworking with Cisco. It would make an excellent first purchase for a future Cisco expert or a fine "fundamentals" reference for more accomplished network engineers. --David Wall
Topics covered: Internetworking from a theoretical standpoint, backed up by information on how Cisco products handle implementation (meaning, in part, that you get information on which Cisco lines and models are good for which jobs). Technically, readers get the goods on Cisco Internetwork Operating System (IOS), routers, switches, routing protocols, and security. There's great information on the pantheon of Cisco certifications too. --This text refers to an out of print or unavailable edition of this title.

Finally . . . a book that speaks to mere mortals. Well written with good explanations. The authors provide a good balance of technical information while presenting the information in a real-world context. A FANTASTIC place to begin understanding the Cisco line and routing in general.

Wait for 3rd edition; 2nd ed's errors outweigh strengths,

This review is from: Cisco: A Beginners Guide (Paperback)
I am a senior engineer for network security operations. I am not a Cisco guru but I am fairly well versed in LAN technologies and protocols. I read "Cisco: A Beginner's Guide, 2nd Edition" (CABG:2E) to learn about the products and services offered by the world's networking leader. I hoped to recommend CABG:2E to my junior network security analysts. Unfortunately, the book's error count makes it too confusing for networking novices. Those who are experienced enough to recognize the book's problems probably don't need to read it.Reading a technical book is an issue of trust. I can tolerate a few errors. Several errors make me uneasy. Multiple errors make me question the entire work; the authors have lost my trust. I didn't lose complete faith in CABG:2E, but I was uneasy. For example, p. 74 says TCP sequence numbers count packets; they actually count bytes of data. On p. 75, the authors imply that SYN and FIN are the only TCP "code bits," omitting URG, PSH, RST, and ACK. On p. 71, SMTP is listed as a UDP protocol while SNMP is associated with TCP; they should be swapped. P. 75 oddly states "the TCP connection process is often referred to as the 'three-way handshake' because the second step involves sending the receiving station two TCP segments at once." How about SYN - SYN/ACK - ACK as three packets, hence a three-way handshake? The authors have a lot of trouble understanding denial of service attacks as well. On p. 280 they equate DoS to sending "infinite emails" (?) and on p. 289 they invent the term "FINflood" to explain why Cisco CBAC tracks TCP finwait-time. (No such "FINflood" attack exists.) P. 553 mentions "FINwait" as another (nonexistent) DoS method. Finally, I'll pin one early error on an editor or spell checker; p. 38's mention of "du jour" standards should say "de jure." I wouldn't be so concerned with these errors in a book for advanced users, since I imagine experienced readers would notice and discount them. I can't expect "beginners" (the target audience) to recognize these mistakes. (Disclaimer: I received a free review copy from the publisher.)
