2.3 Debugging the System
2.3.1 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.
