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 the debugging command output as debug messages to the device information
center. The information center then sends the messages to appropriate destinations based on the
log output configuration. For more information about configuring debug message output, see
Network Management and Monitoring Configuration Guide
.
