Chapter 8 Configuring Asynchronous Connections

Troubleshooting Asynchronous Problems

If you are having problems or if the output that you received during the

verification steps is very different from that shown in the command output

examples, you can troubleshoot your router, using the Cisco IOS debug

commands. The debug commands provide extensive command output that is not

included in this document.

Caution If you are not familiar with Cisco IOS debug commands, you should read the

“Using Debug Commands” section in the “Introduction to Router

Configuration” chapter before attempting any debugging.

The following debug commands are helpful in troubleshooting asynchronous

configurations. Follow these commands with the ping command to display debug

output:

• debug modem

• debug chat-script

• debug dialer

• debug ppp negotiation
