Debugging a feature module
Output of 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.
To debug a feature module and display the debugging information on a terminal:
