System debugging
Introduction to 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:
•
Protocol debugging switch, which controls protocol-specific debugging information.
•
Screen output switch, which controls whether to display the debugging information on a certain
screen.
illustrates, assume the device can provide debugging for the three modules 1, 2, and 3. The
debugging information can be output on a terminal only when both the protocol debugging switch and
the screen output switch are turned on.

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
