Interactive Token-Ring Network Troubleshooting
by Daniel J. Nassar and Timothy Haight
How to Navigate This Essay
This is the one of the most interactive chapters in
Interactive Network Design Manual.
In this chapter, we actually
run you through decision trees in interactive troubleshooting routines,
much as in an expert system. You start from a page of common network symptoms
and work your way through tests and results until you arrive at a solution
that solves your problem.
Many fault symptoms and causes are associated with failures of fault domains,
lobe areas, and network components. When attempting to troubleshoot these
areas in the Token-Ring architecture, you must make many correct decisions
when choosing the path that leads to the cause of your system's failure.
Your troubleshooting skills will become more effective
as your decisions
become more astute and precise. The following pages were created to help
your diagnostic decision-making by simulating the correct thought process
for fault-isolation when troubleshooting a Token-Ring network.
Take the time to carefully read and follow each step before you take any
of the defined actions on a page you are currently reading. Also, make sure
to thoroughly read any NOTE:
While you are using these procedures, it is a good idea to take memos on
your troubleshooting steps and results.
For More Information...
Those who desire further information supporting the procedures here will
find relevant content in Daniel J. Nassar's
Network Optimization and
Troubleshooting: Achieve Maximum Network Performance.
Indiana: New Riders Publishing, 1994). A new book by Daniel J. Nasser also
containing this material,
Ethernet and Token-Ring Network Optimization
is expected to be publised soon by M&T Books, a division of Henry Holt
& Co., New York.
The technical content of the troubleshooting routines in this chapter is
the work of Daniel J. Nassar. Timothy Haight prepared these routines for
interactive presentation on the World Wide Web. The authors welcome any
comments which will help us improve these procedures. You can send e-mail
