CCNPv6 TSHOOT Section 2—Troubleshooting Reference Information General Troubleshooting Process As a general guideline, you can use the following general troubleshooting process described in the course. 1. Define the problem (symptoms). 2. Gather information. 3. Analyze the information. 4. Propose a hypothesis (possible cause). 5. Test the hypothesis. 6. Eliminate or accept the hypothesis. 7. Solve the problem. 8. Document the problem. Command Summary The table lists useful commands for this lab. The sample output is shown on following pages. Command Key Information Displayed show line vty 0 show users show radius server-group all show radius statistics debug radius authentication show aaa servers show aaa method-lists all debug aaa authentication debug aaa authorization Displays the physical serial interface characteristics of a vty line as well as the transport input and output allowed (for example: Telnet or SSH). Displays device lines in use (for example: con, vty 0, vty 1), the username logged in, and the IP address of the connected host. Displays the RADIUS servers defined in the group specified (default group is radius). The server IP address and port numbers are listed. Displays the RADIUS message statistics for authentication and accounting communication between the network device and the RADIUS server. Output includes packets with and without responses, response delay, and timeouts. Source port numbers are also listed. Displays real-time interaction and message exchange between the network device, the calling station, and the RADIUS server. Authentication success or failure is indicated. Displays AAA server host information, including type (RADIUS or TACACS), IP address, port numbers in use, and AAA requests, successes, and failures. Displays the names of AAA method lists currently defined, the type of validation in use, and the sequence of application (for example: server group, local, or none). Displays the method list defined and being used for AAA authentication (for example: TELNET_LINES). Displays the method list defined and being used for AAA authorization.
