Objectives

Part 1: Set Up the Network Topology (Ethernet only).

Part 2: Configure PC Hosts.

Part 3: Configure workstation Address Information.

Part 4: Test connectivity between two PC hosts.

Background / Scenario

Networks are constructed of three major components: hosts, switches, and routers. In this lab, you will build a simple network with two hosts and a switch.

Required Resources

1 Switch.

2 PCs (Windows 7 or 8 with terminal emulation program, such as Tera Term)

Ethernet cables as shown in the topology

Set Up the Network Topology (Ethernet only)

In Part 1, you will cable the devices together according to the network topology.

Power on the devices.

Power on all devices in the topology. The switches do not have a power switch; they will power on as soon as you plug in the power cord.

Connect the PCs to switch.

Connect one end of the first Ethernet cable to the NIC port on PC-A. Connect the other end of the cable to the switch. After connecting the PC to the switch, you should see the light turn amber and then green, indicating that PC-A has been connected correctly.

Connect one end of the last Ethernet cable to the NIC port on PC-B. Connect the other end of the cable to the switch. After connecting the PC to the switch, you should see the light for turn amber and then green, indicating that the PC-B has been connected correctly.

Visually inspect network connections.

After cabling the network devices, take a moment to carefully verify the connections to minimize the time required to troubleshoot network connectivity issues later.

Configure PC Hosts

Configure static IP address information on the PCs.

Click the Windows Start icon and then select Control Panel.

In the Network and Internet section, click the View network status and tasks link.

Note: If the Control Panel displays a list of icons, click the drop-down option next to the View by: and change this option to display by Category.

In the left pane of the Network and Sharing Center window, click the Change adapter settings link.

The Network Connections window displays the available interfaces on the PC. Right-click the Local Area Connection interface and select Properties.

Select the Internet Protocol Version 4 (TCP/IPv4) option and then click Properties.

Note: You can also double-click Internet Protocol Version 4 (TCP/IPv4) to display the Properties window.

Click the Use the following IP address radio button to manually enter an IP address, subnet mask, and default gateway.

Note: In the above example, the IP address and subnet mask have been entered for PC-A. The default gateway has not been entered, because there is no router attached to the network. Refer to the Addressing Table on page 1 for PC-B’s IP address information.

After all the IP information has been entered, click OK. Click OK on the Local Area Connection Properties window to assign the IP address to the LAN adapter.

Repeat the previous steps to enter the IP address information for PC-B.

Verify PC settings and connectivity.

Use the command prompt (cmd.exe) window to verify the PC settings and connectivity.

From PC-A, click the Windows Start icon, type cmd in the Search programs and files box, and then press Enter.

The cmd.exe window is where you can enter commands directly to the PC and view the results of those commands. Verify your PC settings by using the ipconfig /all command. This command displays the PC hostname and the IPv4 address information.

Type ping 192.168.1.11 and press Enter.

Were the ping results successful? ______________________

If not, troubleshoot as necessary.

Note: If you did not get a reply from PC-B, try to ping PC-B again. If you still do not get a reply from PC-B, try to ping PC-A from PC-B. If you are unable to get a reply from the remote PC, then have your instructor help you troubleshoot the problem.

Reflection

What could prevent a ping from being sent between the PCs?

Note: It may be necessary to disable the PC firewall to ping between PCs.
