System debugging
Introduction to system debugging
The device provides various debugging functions. For the majority of protocols and features supported,
the system provides debugging information to help users diagnose errors.
The following two switches control the display of debugging information:
•
Protocol debugging switch: Controls protocol-specific debugging information.
• Screen output switch: Controls whether to display the debugging information on a certain screen.
Displaying debugging information
As shown in Figure 3 , assume that 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.
