Debugging the System
Enabling/Disabling System Debugging
The device provides various debugging functions. For the majority of protocols and features supported,
the system provides corresponding debugging information to help users diagnose errors.
The following two switches control the display of debugging information:
z Protocol debugging switch, which controls protocol-specific debugging information
z Screen output switch, which controls whether to display the debugging information on a certain
screen.
Figure 2-1 illustrates the relationship between the protocol debugging switch and the screen output
switch. Assume that the device can output debugging information to module 1, 2 and 3. Only when both
are turned on can debugging information be output on a terminal.

Displaying debugging information on the terminal is the most commonly used way to output debugging
information. You can also output debugging information to other directions. For details, refer to
Information Center Operation.
