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 Network Computing's
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. (Indianapolis,
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
