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.
Figure 170 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.
