Building a Switch-based Network LAB 7

Objective Create a simple network between two PCs using a switch Identify the proper cable to connect the two PCs Configure workstation IP address information Test connectivity using the ping command.

Background / Preparation This lab focuses on the ability to connect two PCs to create a simple switch-based Ethernet LAN using two workstations. A switch is a networking concentration device sometimes referred to as a multiport bridge. Switches are relatively inexpensive and easy to install.

Background / Preparation When operating in fullduplex mode, they provide dedicated bandwidth to workstations. Switches eliminate collisions by creating microsegments between ports to which the two workstations are attached. They are appropriate for small to large LANs with moderate to heavy traffic. In addition to the physical and data link connections, which are Layers 1 and 2, the computers must also be configured with the correct IP network settings, which is Layer 3, so that they can communicate. Since this lab uses a switch, a basic Category 5/5e UTP straight- through cable is needed to connect each PC to the switch. This is referred to as a patch cable or horizontal cabling, which is used to connect workstations and a typical LAN.

Background / Preparation Start this lab with the equipment turned off and with cabling disconnected. Work in teams of two with one person per PC. The following resources will be required: Two workstations with an Ethernet 10/100 NIC installed Ethernet 10Base T or Fast Ethernet switch Several Ethernet cables, which are both straight-through and crossover, to choose from for connecting the two workstations

Step 1 Identify the proper Ethernet cable and connect the two PCs The connection between the two PCs and a switch will be accomplished using a Category 5 or 5e straight through patch cable. Locate a cable that is long enough to reach from each PC to the switch. Attach one end to the NIC and the other end to a port on the switch. Be sure to examine the cable ends carefully and select only a straight-through cable. b. What kind of cable is required to connect from NIC to switch?__________________________

Step 2 Verify the physical connection a. Plug in and turn on the computers. To verify the computer connections, insure that the link lights on the both PC NICs and the switch interfaces are lit

Step 3 Access the IP settings window •Click on Start > Settings > Control Panel and then click the Network Connection icon. •Select the Local Area Network Connection and click on Change settings of this connection. •Select the TCP/IP protocol icon that is associated with the NIC in this PC. •Click on Properties and click on Use the following IP address.

See the example below:

Step 4 Configure TCP/IP settings for the two PCs a. Set the IP address information for each PC according to the information in the table. b. Note that the default gateway IP address is not required, since these computers are directly connected. The default gateway is only required on local area networks that are connected to a router.

Step 5 Access the Command or MS-DOS prompt a. Use the Start menu to open the Command Prompt (MS-DOS-like) window: Start > Programs > Accessories > Command Prompt

Step 6 Verify that the PCs can communicate a. Test connectivity from one PC to the other by pinging the IP address of the opposite computer. Use the following command at the command prompt. ping 192.168.1.1 (or 192.168.1.2) b. Look for results similar to those shown below. If not, check the PC connections and TCP/IP settings for both PCs. What was the ping result?

Step 7 Confirm the TCP/IP network settings Type the ipconfig command from the Command Prompt. Record the results:

Step 8 Restore the PCs to their original IP settings, disconnect the equipment, and store the cables
