Debugging information control switches
The following two switches control the debugging information output:
• Protocol debugging switch—Controls protocol-specific debugging information.
• Screen output switch—Controls whether to display the debugging information on a certain screen.
As shown in Figure 7, a

The debugging information can be output on a terminal only when both the protocol debugging switch
and the screen output switch are turned on.
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
output on a terminal (including console or VTY) for display. You can also send debugging information to
other destinations. For more information, see "Configuring the information center."

Debugging a feature
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.
