Debugging a feature module
Output from debugging commands is memory intensive. To guarantee system performance, enable
debugging only for modules that are in an exceptional condition. When debugging is complete, use the
undo debugging all command to disable all the debugging functions.
Configure the debugging, terminal debugging and terminal monitor commands before you can display
detailed debugging information on the terminal. For more information about the terminal debugging
and terminal monitor commands, see System Maintenance Command Reference.
