In: Computer Science
Note: If the switch did not prompt you for a password, then you did not configure the login parameter in Step 2.
Step 4: Secure privileged mode access.
Set the enable password to c1$c0. This password protects access to privileged mode.
Note: The 0 in c1$c0 is a zero, not a capital O. This password will not grade as correct until after you encrypt it in Step 8.
S1> enable
S1# configure terminal
S1(config)# enable password c1$c0
S1(config)# exit
%SYS-5-CONFIG_I: Configured from console by console
S1#
Step 5: Verify that privileged mode access is secure.
a. Enter the exit command again to log out of the switch.
b. Press <Enter> and you will now be asked for a password:
User Access Verification
Password:
c. The first password is the console password you configured for line con 0. Enter this password to return to user EXEC mode.
d. Enter the command to access privileged mode.
e. Enter the second password you configured to protect privileged EXEC mode.
f. Verify your configurations by examining the contents of the running-configuration file:
S1# show running-config
Notice how the console and enable passwords are both in plain text. This could pose a security risk if someone is looking over your shoulder.
Step 6: Configure an encrypted password to secure access to privileged mode.
The enable password should be replaced with the newer encrypted secret password using the enable secret command. Set the enable secret password to itsasecret.
S1# config t
S1(config)# enable secret itsasecret
S1(config)# exit
S1#
Note: The enable secret password overrides the enable password. If both are configured on the switch, you must enter the enable secret password to enter privileged EXEC mode.
Step 7: Verify that the enable secret password is added to the configuration file.
a. Enter the show running-config command again to verify the new enable secret password is configured.
Note: You can abbreviate show running-config as
S1# show run
b. What is displayed for the enable secret password?
c. Why is the enable secret password displayed differently from what we configured?
Step 8: Encrypt the enable and console passwords.
As you noticed in Step 7, the enable secret password was encrypted, but theenable and console passwords were still in plain text. We will now encrypt these plain text passwords using the service password-encryptioncommand.
S1# config t
S1(config)# service password-encryption
S1(config)# exit
If you configure any more passwords on the switch, will they be displayed in the configuration file as plain text or in encrypted form? Explain.
Part 3: Configure a MOTD Banner
Step 1: Configure a message of the day (MOTD) banner.
The Cisco IOS command set includes a feature that allows you to configure messages that anyone logging onto the switch sees. These messages are called message of the day, or MOTD banners. Enclose the banner text in quotations or use a delimiter different from any character appearing in the MOTD string.
S1# config t
S1(config)# banner motd "This is a secure system.Authorized Access Only!"
S1(config)# exit
%SYS-5-CONFIG_I: Configured from console by console
S1#
1) When will this banner be displayed?
2) Why should every switch have a MOTD banner?
Part 4: Save Configuration Files to NVRAM
Step 1: Verify that the configuration is accurate using the show run command.
Step 2: Save the configuration file.
You have completed the basic configuration of the switch. Now back up the running configuration file to NVRAM to ensure that the changes made are not lost if the system is rebooted or loses power.
S1# copy running-config startup-config
Destination filename [startup-config]?[Enter]
Building configuration...
[OK]
What is the shortest, abbreviated version of the copy running-config startup-config command?
Step 3: Examine the startup configuration file.
Which command will display the contents of NVRAM?
Are all the changes that were entered recorded in the file?
Part 5: Configure S2
You have completed the configuration on S1. You will now configure S2. If you cannot remember the commands, refer to Parts 1 to 4 for assistance.
Configure S2 with the following parameters:
a. Name device: S2
b. Protect access to the console using the letmein password.
c. Configure an enable password of c1$c0 and an enable secret password of itsasecret.
d. Configure a message to those logging into the switch with the following message:
Authorized access only. Unauthorized access is prohibited and violators will be prosecuted to the full extent of the law.
e. Encrypt all plain text passwords.
f. Ensure that the configuration is correct.
g. Save the configuration file to avoid loss if the switch is powered down.

What is displayed for the enable secret password?
yes it will because its not encrypted bunch of
symbols
Why is the enable secret password displayed
differently from what we configured?
it is encrypted within those symbols
If you configure any more passwords on the switch, will they be displayed in the configuration file as plain text or in encrypted form?
they will be displayed a plain text because the command is not a always a running command
When will this banner be displayed?
when the user gets on the switch
Why should every switch have a MOTD banner?
it keeps the user updated on whats going on
