EBUGGING

You can use the following display commands to check the status and 
configuration information about the system. For information about protocols and 
ports, and the associated display commands, refer to relevant sections.

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.
