Using debug Commands

The debug hw-module subslot command is intended for use by Cisco Systems technical support personnel. For more information about the debug hw-module subslot command, see the Cisco 7600 Series Router SIP, SSC, and SPA Software Configuration Guide .

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.

For information about other debug commands supported on the Cisco 7600 Series ES+ line card and to view the explanations and recommended actions for the Cisco 7600 series router error messages, including messages related to the Cisco 7600 Series ES+ line card, refer to the following documents:
