Objectives
- Part 1: Set Up the Network Topology
- Part 2: Configure PC Hosts
- Part 3: Configure and Verify Basic Switch Settings
Background / Scenario
In this Packet Tracer Physical Mode (PTPM) activity, you will build a simple network with two hosts and two switches. You will also configure basic settings including hostname, local passwords, and login banner. Use show commands to display the running configuration, IOS version, and interface status. Use the copy command to save device configurations.
You will apply IP addressing for to the PCs and switches to enable communication between the devices. Use the ping utility to verify connectivity.
Instructions
Part 1:Set Up the Network Topology
Power on the PCs and cable the devices according to the topology. To select the correct port on a switch, right click and select Inspect Front. Use the Zoom tool, if necessary. Float your mouse over the ports to see the port numbers. Packet Tracer will score the correct cable and port connections.
- a. There are several switches, routers, and other devices on the Click and drag switches S1 and S2 to the Rack. Click and drag two PCs to the Table.
- b. Power on the PCs.
- c. On the Cable Pegboard, click a CopperCross-Over Click the FastEthernet0/1 port on S1 and then click the FastEthernet0/1 port on S2 to connect them. You should see the cable connecting the two ports.
- d. On the Cable Pegboard, click a CopperStraight-Through Click the FastEthernet0/6 port on S1 and then click the FastEthernet0 port on PC-A to connect them.
- e. On the Cable Pegboard, click a CopperStraight-Through Click the FastEthernet0/18 port on S2 and then click the FastEthernet0 port on PC-B to connect them.
- f. Visually inspect network connections. Initially, when you connect devices to a switch port, the link lights will be amber. After a minute or so, the link lights will turn green.
Part 2:Configure PC Hosts
Configure static IP address information on the PCs according to the Addressing Table.
- a. Click PC-A> Desktop > IP Configuration. Enter the IP address for PC-A (192.168.1.10) and the subnet mask (255.255.255.0), as listed in the IP addressing table. You can leave default gateway blank at this time because there is no router attached to the network.
- b. Close the PC-A
- c. Repeat the previous steps to assign the IP address information for PC-B, as listed in the Addressing Table.
- d. Click PC-A> Desktop > Command Prompt. Use the ipconfig /all command at the prompt to verify settings.
- e. Enter ping 192.168.1.11at the prompt to test the connectivity to PC-B. The ping should be successful, as shown in the following output. If the ping is not successful, check the configurations on both of the PCs and troubleshoot as necessary.

Part 3: Configure and Verify Basic Switch Settings
a. On the Cable Pegboard, click a Console cable. Connect the console cable between S1 and PC-A.
b. Establish a console connection to the switch S1 from PC-A using the Packet Tracer generic Terminal program (PC-A > Desktop > Terminal). Press ENTER to get the Switch> prompt.
c. You can access all switch commands in privileged EXEC mode. 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. Enter privileged EXEC mode by entering the enable command.
Switch> enable Switch#
d. The prompt changed from Switch> to Switch# which indicates privileged EXEC mode. Enter global configuration mode.
Switch# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Switch(config)#
e. The prompt changed to Switch(config)# to reflect global configuration mode. Give the switch a name according to the Addressing Table.
Switch(config)# hostname S1
f. Enter local passwords. Use class as the privileged EXEC password and cisco as the password for console access.
S1(config)# enable secret class S1(config)# line con 0 S1(config-line)# password cisco S1(config-line)# login S1(config-line)# exit
g. Configure and enable the VLAN 1 interface according to the Addressing Table.
S1(config)# interface vlan 1 S1(config-if)# ip address 192.168.1.1 255.255.255.0 S1(config-if)# no shutdown
h. A login banner, known as the message of the day (MOTD) banner, should be configured to warn anyone accessing the switch that unauthorized access will not be tolerated. Configure an appropriate MOTD banner to warn about unauthorized access.
S1(config)# banner motd #Unauthorized access is strictly prohibited and prosecuted to the full extent of the law.# S1(config)# exit
i. Save the configuration to the startup file on non-volatile random access memory (NVRAM).
S1# copy running-config startup-config Destination filename [startup-config]? [Enter] Building configuration… [OK] S1#
j. Display the current configuration.
S1# show running-config Building configuration… <output omitted>
k. Display the IOS version and other useful switch information.
S1# show version Cisco IOS Software, C2960 Software (C2960-LANBASEK9-M), Version 15.0(2)SE, RELEASE SOFTWARE (fc1) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2012 by Cisco Systems, Inc. Compiled Sat 28-Jul-12 00:29 by prod_rel_team <output omitted>
l. Display the status of the connected interfaces on the switch.
S1# show ip interface brief S1#show ip interface brief Interface IP-Address OK? Method Status Protocol FastEthernet0/1 unassigned YES manual up up FastEthernet0/2 unassigned YES manual down down FastEthernet0/3 unassigned YES manual down down FastEthernet0/4 unassigned YES manual down down FastEthernet0/5 unassigned YES manual down down FastEthernet0/6 unassigned YES manual up up FastEthernet0/7 unassigned YES manual down down FastEthernet0/8 unassigned YES manual down down <output omitted> GigabitEthernet0/1 unassigned YES manual down down GigabitEthernet0/2 unassigned YES manual down down Vlan1 192.168.1.1 YES manual up up S1#
m. Repeat the previous steps to configure switch S2. Make sure the hostname is configured as S2.
enable config terminal hostname S2 enable secret class line console 0 password cisco login exit interface vlan 1 ip address 192.168.1.2 255.255.255.0 no shutdown banner motd #Unauthorized access is strictly prohibited and prosecuted to the full extent of the law.# end copy running-config startup-config
n. Record the interface status for the following interfaces.
| Interface | S1 Status | S1 Protocol | S2 Status | S2 Protocol |
|---|---|---|---|---|
| F0/1 | Up | Up | Up | Up |
| F0/6 | Up | Up | Down | Down |
| F0/18 | Down | Down | Up | Up |
| VLAN 1 | Up | Up | Up | Up |
o. From a PC, ping S1 and S2. The pings should be successful.
p. From a switch, ping PC-A and PC-B. The pings should be successful.
Reflection Question
Why are some FastEthernet ports on the switches up while others are down?
The FastEthernet ports are up when cables are connected to the ports unless they were manually shutdown by the administrators. Otherwise, the ports would be down.
What could prevent a ping from being sent between the PCs?
Wrong IP address, media disconnected, switch powered off or ports administratively down, firewall.
