Network Topology for This Lab

This lab uses only the switch (SW1) with no activities on the other devices.

Detailed Lab Steps
Step 1.

Connect to SW1’s console port using the simulator. The window will look like a terminal emulator with a cursor at the bottom of the screen and the center of the screen mostly blank.

Step 2.

From the simulator’s terminal-emulator screen, press Enter.

Enter privileged mode using the enable command. Are you prompted for a password?
No

Step 4.

Enter configuration mode using the configure terminal command. What does the command prompt look like after this command? What CLI mode does the prompt imply?
Switch(config)# Config exec

Step 5.

Enter interface configuration mode for interface FastEthernet 0/1 using the interface fastethernet 0/1 command. What does the command prompt look like after this command? What CLI mode does the prompt imply?
Switch(config-if)#

Config Sub Exec

Step 6.

Use the description this is the connection to PC1 command to define an interface description for interface Fa0/1.

Step 7.

Move back to global configuration mode using the exit command.

Step 8.

Use the enable secret ciscopress command to set an enable password so that ciscopress must be entered when a user tries to enter privileged mode.

Step 9.

Use the end command to move back to enable mode.

Step 10.

Use the disable command to move back to user exec mode.

Step 11.

Hint or Answer

3

This lab begins with the switch having all default configuration, which means that no passwords are configured.

4

The command prompt should be Switch(config)#, which implies that you are in global configuration mode.

5

The command prompt should be Switch(config-if)#, which implies that you are in interface configuration mode.

11

You should be prompted for a password now, as a result of having configured the enable secret command earlier in the lab.

Configuration Steps
