 Note:
z The debugging commands are usually used by administrators in diagnosing
network failure.
z Output of the debugging information may reduce system efficiency, especially
during execution of the debugging all command.
z After completing the debugging, you are recommended to use the undo debugging
all command to disable all the debugging functions.
z You must configure the debugging, terminal debugging and terminal monitor
commands first to display the detailed debugging information on the terminal. For
the detailed description on the terminal debugging and terminal monitor
commands, refer to Information Center Commands.
