Configuring System Debugging
Output of the debugging information may reduce system efficiency. The debugging commands are
usually used by administrators in diagnosing 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 is related to the configurations of the information center and the
debugging commands of each protocol and functional module. Displaying the debugging
information on a terminal (including console or VTY) is a common way to output debugging
information. You can also output debugging information to other destinations. For the detailed
configurations, refer to Information Center Commands in the Network Management and Monitoring
Command Reference. By default, you can output debugging information to a terminal by following
these steps:
