Parameters
module-name: Specifies a module by its name, such as arp or device. For a list of supported
modules, use the debugging ? command.

Usage guidelines
Output from debugging commands is memory intensive. To guarantee system performance, enable
debugging only for modules that are in an exceptional condition.
The system sends generated debug messages to the device information center, which then sends
the messages to appropriate destinations based on the log output configuration. For more
information about the information center, see Network Management and Monitoring Configuration
Guide.

# Enable debugging for the device management module.
