After logging in, issue the show run command. Were you able to issue the command? Why or why Enter privileged EXEC mode using the enable command. Were you prompted for a password? Why
c. Exit privileged EXEC mode by using the disable or exit command and press Enter to get started.
Does the MOTD banner look like what you expected? Yes. Note: If it does not, just re-create it using the banner motd command. Step 9: Save the basic configurations. Save the running configuration to the startup configuration from the privileged EXEC prompt. R1 copy running-config startup-config Part 2: Configure Local Authentication In Part 2 of this lab, you configure a local username and password and change the access for the console, aux, and vty lines to reference the router’s local database for valid usernames and passwords. Perform all steps on R1 and R3. The procedure for R1 is shown here. Step 1: Configure the local user database. a. Create a local user account with MD5 hashing to encrypt the password. R1config username user01 secret user01pass b. Exit global configuration mode and display the running configuration. Can you read the user’s password? No, a secret password is encrypted Step 2: Configure local authentication for the console line and login. a. Set the console line to use the locally defined login usernames and passwords. R1config line console 0 R1config-line login local b. Exit to the initial router screen that displays: R1 con0 is now available. Press RETURN to get started. c. Log in using the user01 account and password previously defined. d. What is the difference between logging in at the console now and previously? This time you are prompted to enter a username as well as a password. e. After logging in, issue the show run command. Were you able to issue the command? Why or why not? No. It requires privileged EXEC level. f. Enter privileged EXEC mode using the enable command. Were you prompted for a password? Why or why not? Yes. The new users created will still be required to enter the enable secret password to enter privileged EXEC mode. Step 3: Test the new account by logging in from a Telnet session. a. From PC-A, establish a Telnet session with R1. PC-A telnet 192.168.1.1 b. Were you prompted for a user account? Why or why not? No. The vty lines were not set to use the locally defined accounts as the line 0 console was. c. What password did you use to login? ciscovtypass d. Set the vty lines to use the locally defined login accounts. R1config line vty 0 4 R1config-line login local CCNA Security All contents are Copyright © 1992 –2011 Cisco Systems, Inc. All rights reserved. This document is Cisco Public Information. Page 7 of 31 e. From PC-A, telnet R1 to R1 again. PC-A telnet 192.168.1.1 f. Were you prompted for a user account? Why or why not? Yes. The vty lines are now set to use the locally defined accounts. g. Log in as user01 with a password of user01pass. h. While connected to R1 via Telnet, access privileged EXEC mode with the enable command. i. What password did you use? The enable secret password, cisco12345 j. For added security, set the aux port to use the locally defined login accounts. R1config line aux 0 R1config-line login local k. End the Telnet session with the exit command. Step 4: Save the configuration on R1. a. Save the running configuration to the startup configuration from the privileged EXEC prompt. R1 copy running-config startup-config b. Use HyperTerminal or another means to save the R1 running configuration from Parts 1 and 2 of this lab and edit it so that it can be used to restore the R1 config later in the lab. Note: Remove al l occurrences of “- - More - -.” Remove any commands that are not related to the items you configured in Parts 1 and 2 of the lab, such as the Cisco IOS version number, no service pad, and so on. Many commands are entered automatically by the Cisco IOS software. Also replace the encrypted passwords with the correct ones specified previously. Step 5: Perform steps 1 through 4 on R3 and save the configuration. a. Save the running configuration to the startup configuration from the privileged EXEC prompt. R3 copy running-config startup-config b. Use HyperTerminal or another means to save the R3 running configuration from Parts 1 and 2 of this lab and edit it so that it can be used to restore the R3 config later in the lab. Part 3: Configure Local Authentication Using AAA on R3 Task 1: Configure the Local User Database Using Cisco IOS Note: To configure AAA using CCP, skip to Task 3. Step 1: Configure the local user database. a. Create a local user account with MD5 hashing to encrypt the password. R3config username Admin01 privilege 15 secret Admin01pass b. Exit global configuration mode and display the running configuration. Can you read the user’s password? No, a secret password is encrypted.
