Using Debug Commands; Troubleshooting Sip And Spa - Cisco uBR10012 Hardware Installation Manual

Using debug Commands

Using debug Commands
The debug command is primarily used by Cisco technical support personnel.
Because debugging output is assigned high priority in the CPU process, it can render the system unusable.
Caution
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.
Following are some debug commands for debugging SIPs and SPAs on the Cisco uBR10012 router:
• debug c10k-jacket2spa—Enables debug information for the Cisco Wideband SIP card.
• debug c10k-jacket4spa—Enables debug information for the Cisco SIP-600 card.
• debug hw-module bay—Enables debugging information for a SPA.
• debug cable fn—Enables debugging information for cable fiber nodes.
• debug cable wbcmts—Enables debug information for the wideband CMTS.
• debug hw-module subslot—Enables debug information for a SPA and all of its interfaces.
For information about other debug commands supported on the Cisco uBR10012 router, see the
