Interface Debugging
Interface debugging is used to obtain information that is specific to inter-
faces, interface signaling, and interface processes. The same caution should
be used with interface-related debug commands as with the global com-
mands. The more focused the debug through the use of options, the easier it
is to isolate the problem.
Interface-oriented commands are provided in Table 4.12. Again, each of
these commands has additional options available. To see the related
options, use the commands listed, followed by a question mark. Most of
these commands will be described and applied in later chapters.
