From the Telnet window, exit privileged EXEC mode using the disable command. Try to enter Erase the startup config and then issue the reload command to restart the router.
e. From the Telnet window, exit privileged EXEC mode using the disable command. Try to enter
privileged EXEC mode again, but use a bad password this time. Observe the debug output on R3, noting that the status is “FAIL” this time.

From the Telnet window, exit the Telnet session to the router. Then try to open a Telnet session to the router again, but this time try to log in with the username Admin01 and a bad password. From the console window, the debug output should look similar to the following. Dec 26 15:49:32.339: AAAAUTHENLOGIN 000000AA: Pick method list default What message was displayed on the Telnet client screen? Authentication failed Turn off all debugging using the undebug all command at the privileged EXEC prompt. Part 4: Configure Centralized Authentication Using AAA and RADIUS. In Part 4 of the lab, you install RADIUS server software on PC-A. You then configure router R1 to access the external RADIUS server for user authentication. The freeware server WinRadius is used for this section of the lab. Task 1: Restore Router R1 to Its Basic Settings To avoid confusion as to what was already entered and the AAA RADIUS configuration, start by restoring router R1 to its basic configuration as performed in Parts 1 and 2 of this lab. Step 1: Erase and reload the router. a. Connect to the R1 console, and log in with the username Admin01 and password Admin01pass. b. Enter privileged EXEC mode with the password cisco12345.c. Erase the startup config and then issue the reload command to restart the router.

When the router restarts, enter privileged EXEC mode with the enable command, and then enter global config mode. Use the HyperTerminal Transfer Send File function, cut and paste or use another method to load the basic startup config for R1 that was created and saved in Part 2 of this lab. b. Test connectivity by pinging from host PC-A to PC-C. If the pings are not successful, troubleshoot the router and PC configurations until they are. c. If you are logged out of the console, log in again as user01 with password user01pass, and access privileged EXEC mode with the password cisco12345. d. Save the running config to the startup config using the copy run start command.Parts
