Using debug Commands
The

command is intended for use by Cisco Systems technical support
personnel. For more information about the
debug hw-module subslot

Caution
Because debugging output is assigned high priority in the CPU process, it can render the system
unusable. For this reason, use
debug
commands only to troubleshoot specific problems or during
troubleshooting sessions with Cisco technical support staff. Moreover, it is best to use
debug
commands
during periods of lower network traffic and fewer users. Debugging during these periods decreases the
likelihood that increased
debug
command processing overhead will affect system use.
