Section 5 Configuring PPP and Authentication
Testing Asynchronous PPP Connections
Task 5. Testing Asynchronous PPP Connections
Before you troubleshoot PPP negotiation or AAA authentication, you need to understand what a
successful PPP and AAA debug sequence looks like. In this way, you can save time and effort when
comparing a successful debug session against a faulty completed debug sequence.
5.1 Successful PPP Negotiation Debug
The following steps describe how to initiate a PPP test call and interpret a successful debug sequence.
Step 1
Enter the appropriate debug commands:
5800-NAS#debug ppp authentication
PPP authentication debugging is on
5800-NAS#debug aaa authentication
AAA Authentication debugging is on
5800-NAS#show debug
General OS:
AAA Authentication debugging is on
PPP:
PPP authentication debugging is on
Step 2
Make sure that your EXEC session receives logging and debug output:
5800-NAS#terminal monitor
Step 3
From the client, send a test call into the NAS by using Dial-Up Networking. Figure 5-2 shows an
example Windows Dial-Up Networking display.
