Preparing to Troubleshoot
The first step in troubleshooting your network is to determine exactly what is
happening; that is, to write down a detailed description of the problem -- what the
system is doing as well as what it is not doing.
Troubleshooting Worksheet
This section poses the initial questions you should answer to narrow the cause of a
problem. Your answers may lead you to such topics as the operation of the
BayStream platform, the BayStream software, the Remote Annex platform, the
physical layer, the data link layer, or the network layer. Subsequent sections
provide instructions on how to further isolate and solve problems.
Determine the scope of a problem by researching and writing down the answers to
the following questions:
1.
What are the symptoms of the problem? Exactly what is happening?
What is not happening?

The more information you have about the symptoms of the problem, the more
easily you can identify the cause.
2.
When did each symptom begin?
Write down the time you learned about each symptom. Examine the event log
for event messages that indicate when the problem occurred. Read the event
message descriptions for clues.

Note: A problem’s symptoms and its underlying cause are not necessarily the
same. For example, if you cannot ping an IP router, the symptom is that you
cannot ping the router; the cause may be a loose cable.
