Troubleshooting LAN problems can be difficult because a variety
of hardware and software components may be involved and because
the problem impacting your system may originate in another part
of the network.
The “Troubleshooting Q and A” section in
this chapter provide quick fix solutions to common network problems
by providing answers to the most frequently asked troubleshooting questions.
Look through the problems identified to see if your problem fits
into any of these categories. If so, you may be able to quickly
identify and recover from the problem without any further investigation.
If, however, you are unable to identify your problem, proceed
to the “100Base-T Checklist” to have a general
view of your system and its possible problems. Then if you are still
unable to identify your problem, proceed to the troubleshooting
flowcharts. The troubleshooting flowcharts provide a logical sequence
of steps to follow when troubleshooting HP-UX LAN. Using the diagnostic
flowcharts provided in this chapter, identify whether the problem
is with HP-UX LAN, any of the connectors, or if it is in some other
part of the LAN network. Verify your assumptions and, it if is limited
to HP-UX LAN software and hardware, correct the problem.
