Identifying Network Problems
There are a number of sources from which to obtain information to identify a network
problem. Many of these sources are the same as those used to verify normal system
operation.
When a network problem occurs, usually more than one problem is reported (for
example, the user may encounter a file-system error at the same time that an event
message is reported). You can organize network problems into a hierarchy of entities,
as shown in Figure 21-1. When you begin to identify a network problem, it is usually
best to determine commonalities between all of the errors reported beginning with the
lowest layers.
This subsection contains examples that show how you can use the following sources
to identify a problem:
•
User Complaints
•
SCF Commands
