Note:
The debugging commands are normally used when the administrator is diagnosing
network failure.
Output of the debugging information may reduce system efficiency, especially
during execution of the debugging all command.
After the debugging is completed, users may use the undo debugging all
command to disable all the debugging functions simultaneously.
The debugging information can be displayed on the terminal only when the
debugging command and the terminal debugging command are both executed
successfully.
