Introduction
xxix
Chapter 6 is dedicated exclusively to TCP/IP troubleshooting. Commands
and techniques are discussed in detail. A summary sheet is provided at the
end of the chapter that is a great quick reference guide.
Chapter 7 covers serial line and Frame Relay troubleshooting. The show
and debug commands that are specific to these technologies are introduced.
Chapter 8 is dedicated to ISDN connectivity issues. Chapters 9 and 10
deal with LAN protocols, such as Novell and AppleTalk. Both debug and
show
commands relating to these protocols are discussed thoroughly.
Chapter 11 covers the Cisco Catalyst 5000 switch and switched Ethernet
networks. SPAN and other troubleshooting targets are also addressed.
Chapter 12 provides information about Cisco Systems and the information
that it provides.
Each chapter ends with review questions that are specifically designed to
help you retain the knowledge presented. To really nail down your skills,
read each question carefully, and, if possible, work through the hands-on
labs in some of the chapters.
