Configuring system debugging
Output of the debugging information may reduce system efficiency. Administrators usually use the
debugging commands to diagnose network failure. After completing the debugging, disable the
corresponding debugging function, or use the undo debugging all command to disable all the
debugging functions.
Output of debugging information depends on the configurations of the information center and the
debugging commands of each protocol and functional module. Displaying the debugging information
on a terminal (including a console or VTY) is a common way to output debugging information. You can
also output debugging information to other destinations. For more information, see the Network
Management and Monitoring Command Reference.
Follow these to output debugging information to a terminal:
