Part 1: Verify the Default Switch Configuration

Part 2: Configure a Basic Switch Configuration

Part 3: Configure a MOTD Banner

Part 4: Save Configuration Files to NVRAM

Part 5: Configure S2

Background / Scenario

In this activity, you will perform basic switch configuration tasks. You will secure access to the command-line interface (CLI) and console ports using encrypted and plain text passwords. You will also learn how to configure messages for users logging into the switch. These message banners are also used to warn unauthorized users that access is prohibited.

Note: In Packet Tracer, the Catalyst 2960 switch uses IOS version 12.2 by default. If required, the IOS version can be updated from a file server in the Packet Tracer topology. The switch can then be configured to boot to IOS version 15.0, if that version is required.


Part 1:Verify the Default Switch Configuration

Step 1:Enter privileged EXEC mode.

You can access all switch commands from privileged EXEC mode. However, because many of the privileged commands configure operating parameters, privileged access should be password-protected to prevent unauthorized use.

The privileged EXEC command set includes the commands available in user EXEC mode, many additional commands, and the configure command through which access to the configuration modes is gained.

  1. Click S1 and then the CLI tab. Press Enter.
  2. Enter privileged EXEC mode by entering the enable command:

Open Configuration Window for S1

Switch> enable


Notice that the prompt changed to reflect privileged EXEC mode.

Step 2:Examine the current switch configuration.

Enter the show running-config command.

Switch# show running-config

Answer the following questions:

How many Fast Ethernet interfaces does the switch have?

Type your answers here.


How many Gigabit Ethernet interfaces does the switch have?


What is the range of values shown for the vty lines?

0 -15

Which command will display the current contents of non-volatile random-access memory (NVRAM)?

show startup-configuration

Why does the switch respond with startup-config is not present?

It displays this message because the configuration file was not saved to NVRAM. Currently it is only located in RAM.

Part 2:Create a Basic Switch Configuration

Step 1:Assign a name to a switch.

To configure parameters on a switch, you may be required to move between various configuration modes. Notice how the prompt changes as you navigate through the switch.

Switch# configure terminal

Switch(config)# hostname S1

S1(config)# exit


Step 2:Secure access to the console line.

To secure access to the console line, access config-line mode and set the console password to letmein.

S1# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

S1(config)# line console 0

S1(config-line)# password letmein

S1(config-line)# login

S1(config-line)# exit

S1(config)# exit

%SYS-5-CONFIG_I: Configured from console by console



Why is the login command required?

In order for the password checking process to work, it requires both the login and password commands.

Step 3:Verify that console access is secured.

Exit privileged mode to verify that the console port password is in effect.

S1# exit

Switch con0 is now available

Press RETURN to get started.

User Access Verification



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


Step 5:Verify that privileged mode access is secure.

  1. Enter the exit command again to log out of the switch.
  2. Press <Enter> and you will now be asked for a password:

User Access Verification


  1. The first password is the console password you configured for line con 0. Enter this password to return to user EXEC mode.
  2. Enter the command to access privileged mode.
  3. Enter the second password you configured to protect privileged EXEC mode.
  4. Verify your configuration by examining the contents of the running-configuration file:

S1# show running-config

Notice that the console and enable passwords are both in plain text. This could pose a security risk if someone is looking over your shoulder or obtains access to config files stored in a backup location.

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


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.

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


What is displayed for the enable secret password?


Why is the enable secret password displayed differently from what we configured?

The enable secret is shown in encrypted form, whereas the enable password is in plain text.

Step 8:Encrypt the enable and console passwords.

As you noticed in Step 7, the enable secret password was encrypted, but the enable and console passwords were still in plain text. We will now encrypt these plain text passwords using the service password-encryption command.

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.

The service password-encryption command encrypts all current and future passwords.

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 motdThis is a secure system. Authorized Access Only!

S1(config)# exit

%SYS-5-CONFIG_I: Configured from console by console



When will this banner be displayed?

The message will be displayed when someone accesses the switch through the console port.

Why should every switch have a MOTD banner?

Every switch should have a banner to warn unauthorized users that access is prohibited. Banners can also be used for sending messages to network personnel/technicians (such as impending system shutdowns or who to contact for access).

Part 4:Save and Verify Configuration Files to NVRAM

Step 1:Verify that the configuration is accurate using the show run command.

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…


Close Configuration Window for S1


What is the shortest, abbreviated version of the copy running-config startup-config command?

cop r s

Examine the startup configuration file.

Which command will display the contents of NVRAM?

show startup-config

Are all the changes that were entered recorded in the file?

Yes, it is the same as the running configuration.

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:

Open Configuration Window for S2

  1. Device name: S2
  2. Protect access to the console using the letmein password.
  3. Configure an enable password of c1$c0 and an enable secret password of itsasecret.
  4. Configure an appropriate message to those logging into the switch.
  5. Encrypt all plain text passwords.
  6. Ensure that the configuration is correct.
  7. Save the configuration file to avoid loss if the switch is powered down.

Close Configuration Window for S2

Switch> enable

Switch# config t

Enter configuration commands, one per line.End with CNTL/Z.

Switch(config)# hostname S2

S2(config)# line console 0

S2(config-line)# password letmein

S2(config-line)# login

S2(config-line)# enable password c1$c0

S2(config)# enable secret itsasecret

S2(config)# banner motd $any text here$

S2(config)# service password-encryption

S2(config)# exit

S2# copy running-config startup-config
