Output of debugging information depends on the configurations of the information center and the
debugging commands of each protocol and functional module. Debugging information is typically
displayed on a terminal (including console or VTY). You can also send debugging information to other
destinations. For more information, see "Configuring the information center."

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.
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 Network Management and Monitoring Command Reference.
