Device Interface IP Address Subnet Mask
PC-A NIC 192.168.1.10 255.255.255.0
PC-B NIC 192.168.1.11 255.255.255.0

Objectives

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

  • Identify cables and ports for use in the network.
  • Cable a physical lab topology.

Part 2: Configure PC Hosts

  • Enter static IP address information on the LAN interface of the hosts.
  • Verify that PCs can communicate using the ping utility.

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. You will apply IP addressing for this lab to the PCs to enable communication between these two devices. Use the ping utility to verify connectivity.

Note: The switches used are Cisco Catalyst 2960s with Cisco IOS Release 15.0(2) (lanbasek9 image). Other switches and Cisco IOS versions can be used.

Required Resources

  • 1 Switch (Cisco 2960 with Cisco IOS Release 15.0(2) lanbasek9 image or comparable)
  • 2 PCs (Windows 10)
  • Two Ethernet cables as shown in the topology

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

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

Step 1: 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.

Step 2: Connect the PCs to the switch.

  1. Connect one end of an Ethernet cable to the NIC port on PC-A. Connect the other end of the cable to F0/6 on S1. After connecting the PC to the switch, you should see the light for F0/6 turn amber and then green, indicating that PC-A has been connected correctly.
  2. Connect one end of an Ethernet cable to the NIC port on PC-B. Connect the other end of the cable to F0/1 on S1. After connecting the PC to the switch, you should see the light for F0/1 turn amber and then green, indicating that the PC-B has been connected correctly.

Step 3: 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.

Part 2: Configure PC Hosts

Step 1: Configure static IP address information on the PCs.

  1. To configure the Network Settings on PC-A, click Start, then click Settings.
  2. In the Settings window click Network & Internet.
  3. In the left pane select Ethernet, then click Change adapter options.
  4. The Network Connections window displays the available network interfaces on the PC. Right-click the Ethernet0 interface and select Properties.
  5. 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.
  6. Click the Use the following IP address radio button to manually enter an IP address, subnet mask, and default gateway. Type in the IP address 192.168.1.10 and the subnet mask 255.255.25.0Note: 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.
  7. After all the IP information has been entered, click OK. Click OK on the Ethernet0 properties window to assign the IP address to the LAN adapter.
  8. Repeat the previous steps to enter the IP address information on PC-B.

Step 2: Verify PC settings and connectivity.

Use the Command Prompt to verify the PC settings and connectivity.

  1. From PC-A, right-click Start, select Command Prompt.
  2. 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.
  3. Type ping 192.168.1.11 and press Enter.Were the ping results successful? ______________________ Yes
    If not, there is good chance that Windows Firewall is blocking ICMP echo requests (ping). Click Start > Settings > Network & Internet > Ethernet > Windows Firewall to turn it off.
    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, ask your Answers to help you troubleshoot the problem.
    Answers Note: If the first ICMP packet times out, this could be a result of the PC resolving the destination address. This should not occur if you repeat the ping as the address is now cached.
