Debug

• If you want to check the realtime traffic that is passing over the wire, you can enable debugging.

• Check for specific types of traffic on the wire. If you want to check for Data Link layer broadcasts, type the following:

  • Router# debug broadcast

• If you want to check RIP traffic on an IP network, type:

  • Router# debug ip rip

• If you want to check IGRP traffic on an IP network, type:

  • Router# debug ip igrp transactions

• Debugging should only be enabled when troubleshooting, and disabled immediately after. Use the no debug all command to disable debugging.
