Essential information on the successful troubleshooting of complex campus networks

Just as a used car can seem to be in good condition to an inexperienced consumer, a network can also feign an appearance that all is running smoothly to the unskilled user. Upon closer examination, though, a true expert can discern when a network is a lemon. Network engineers, administrators, and technicians who manage Cisco and multivendor campus networks know how crucial it is to determine when a network has serious problems and what to do about them, particularly when that network spans buildings and consists of wired and wireless technologies. Known as campus networks, these networks connect tens, hundreds, or even thousands of users at businesses, universities, nonprofit organizations, and government agencies. This informative book teaches the use of Cisco and industry-standard trouble-shooting tools to analyze, diagnose, and fix problems on modern switched and routed networks with information that is based on many years of analyzing real-world, diverse, and complex networks. Written by a pair of authors with over forty years of networking experience between them, this book discusses:
* Techniques for using protocol analyzers, such as the WildPackets EtherPeek and AiroPeek products, to recognize and isolate faulty network behavior
* The OSI Reference Model and the Internet Control Message Protocol (ICMP)
* How Ethernet and 802.11 wireless networks work and how to troubleshoot them when they don't
* Spanning Tree Protocol, which is used on bridged and switched networks, and the configuration and troubleshooting of VLANs
* IP addressing, IP routing protocols, TCP, and an overview of upper-layer TCP/IP protocols
* Troubleshooting for Novell NetWare, AppleTalk, and Windows networking
* WAN technology and trouble-shooting from the perspective of the LAN-oriented network engineer

Good book for network admins

Reviewed in the United States on June 17, 2003

Verified Purchase

My overall impression was that this is a great book. I felt that the first chapter was unnecessary detail, and sort of seemed like chest thumping to me. I find this book to be an excellent reference about just about all aspects of LAN communications. I was not impressed with the WAN protocols however. I sort of expected more of that, as you might find in a Campus network. I keep this book handy, and often find myself using it as a reference when I am unsure of a conclusion I have drawn. I recommend this book to anyone looking for reference material.

A myth-shattering, authoritative and enlightening title

Reviewed in the United States on April 3, 2003

I'm sad I waited so long to read this excellent book. "Troubleshooting Campus Networks" (TCN) was published in Jul 2002, and it belongs on every network administrator's shelf -- now! This is the best networking book since Scott Haugdahl's "Network Analysis and Troubleshooting" and Eric Hall's "Internet Core Protocols." TCN will truly test your networking knowledge; you'll quickly validate the truth and discard the fiction.

So many books discuss networks, but somehow distort subtle points. Authors Oppenheimer and Bardwell know their material inside-out and explain key points in clear, concise prose. Ever hear of the "37% utilization rule for Ethernet?" It's false. Think that TCP sequence numbers count packets? Wrong -- they count bytes of data. And why are sequence numbers seemingly "off by one?" Look at the difference between ordinal and cardinal numbers, described in ch. 9.

TCN displays an uncanny ability to include just the information that is needed. "Reversible half-ASCII," which accounts for odd-looking NetBIOS traces, appears in ch. 12. The sections on Windows networking are first-rate, with helpful comparisons of NetBIOS with IPX, TCP, and NetBEUI. Even theoretical but damaging attack methods, like corrupting Hot Standby Router Protocol messages (ch. 8), are illuminated.
I have two complaints. I would have liked more attention paid to the mechanics of analyzing traffic, including the use of taps. Also, the Windows chapter seemed to end abruptly, just when the dynamics of Windows 2000 networking and port 445 should have appeared.

TCN is designed to educate protocol analysts. People with this skill set can administer LANs, analyzer network-based IDS traffic, and deploy network infrastructure. I thank the authors for their efforts and look forward to their next endeavor.

Super High Quality Book

Reviewed in the United States on August 22, 2002

I've been eagerly reading bits and pieces of my copy of this book ever since it arrived. The amount of highly accurate detail is incredible. I believe 90% of all network books are so sloppily written they're not worth buying. This book is clearly in the top 1% of well-written and informative books.
The book's style is also very clear and understandable. It passes my ultimate test: I can read it at 10-11 PM at night without falling asleep! Almost all of the formulas and binary are made accessible to those with high-school math skills. The book stays focused and contains references to other sources for details that aren't need-to-know or interesting.
Furthermore, the discussion contains valuable protocol and troubleshooting information, info that could be a big help to the
reader in solving real problems in their network. (Of course, a hierarchically designed network built per Oppenheimer's Cisco Press Top-Down Network Design book might not have such problems!)
The protocol analysis aspect also opens the reader's eyes to understanding common protocols and to possible protocol issues. If you don't have protocol analysis software, I hear good things about Ethereal, a free protocol analyzer package for Windows.
Finally, although the title doesn't mention Cisco, there is sample show command output from Cisco devices, also discussion of Cisco-specific information where necessary and appropriate. (The subtitle does include "Cisco" with "LAN protocols" after all.) The book clearly resists the temptation to, for example, pursue routing protocols too deeply, and stays focussed on the campus, providing a well-balanced coverage of troubleshooting for that setting.

Good ideas but VERY outdated

Reviewed in the United Kingdom on March 13, 2012

Verified Purchase

The book contains some good practical information about the processes involved in troubleshooting a network. However, the book is over 10 years old now so is VERY outdated. Some of the topics covered, in massive detail, are no longer implementated in modern switched networks.

I also found that the protocol anaylsis part of the book to be more about understanding TCP/IP/AppleTalk/IPX than about upper layer protocols like HTTP etc (which is actually the reason I bought the book in the first place).

Because of those reasons, I would not recommend this book unless you know you need information about older networks or explicity require information about TCP/IP and older protocols.
