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:
Protocol debugging switch, which controls protocol-specific debugging information
Screen output switch, which controls whether to display the debugging information
on a certain screen.

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.

Note:
Displaying debugging information on the terminal is the most commonly used way to
output debugging information. You can also output debugging information to other
directions. For details, refer to Information Center Operation.
You can use the following commands to enable the two switches.
