Objectives
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
In this activity, you will perform basic switch configurations. 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 banners are also used to warn unauthorized
users that access is prohibited.
Part 1: Verify the Default Switch Configuration
Step 1: Enter privileged mode.
You can access all switch commands from privileged 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 those commands contained in user EXEC mode, as well as the
configure command through which access to the remaining command modes are gained.
a. Click S1 and then the CLI tab. Press <Enter>.
b. Enter privileged EXEC mode by entering the enable command:
Switch> enable
Switch#
Notice that the prompt changed in the configuration to reflect privileged EXEC mode.
Packet Tracer – Configuring Initial Switch Settings
Step 2: Examine the current switch configuration.
a. Enter the show running-config command.
Switch# show running-config
b. Answer the following questions:
How many FastEthernet interfaces does the switch have? 24
How many Gigabit Ethernet interfaces does the switch have? 2
What is the range of values shown for the vty lines? 16
Which command will display the current contents of non-volatile random-access memory (NVRAM)?

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

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.
