Objective
• Create a simple network with two PCs using a switch
• Identify the proper cable to connect the PCs to the switch
• 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. 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 tolarge 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. 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 10BaseT or Fast Ethernet switch
• Several Ethernet cables, which are straight-through and crossover, to choose from
for connecting the two workstations

Step 1 Identify the proper Ethernet cable and connect the two PCs to the switch

a. The connection between the two PCs and the switch will be accomplished using a Category 5 or 5e straight-through patch cable. Locate two cables that are 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? Straight Through Cable

c. What is the category rating of the cable?Category 5 or 5e

d. What is the AWG wire size designation of the cable?24 AWG





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. Are all link lights lit?They should be, otherwise troubleshoot.

Step 3 Access the IP settings window

Note: Be sure to write down the existing IP settings, so that they can be restored at the end of the lab. These include IP address, subnet mask, default gateway, and DNS servers. If the workstation is a DHCP client, it is not necessary to record this information.

Windows 95 / 98 / Me/ users should do the following:

• Click on Start > Settings > Control Panel and then click the Network icon.

• Select the TCP/IP protocol icon that is associated with the NIC in this PC and click on Properties.

• Click on the IP Address tab and the Gateway tab.


Windows NT / 2000 users should do the following:


• Click on Start > Settings > Control Panel and then open the Network and Dial-up Connections folder.

• Click and open the Local Area Connection
icon.

• 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.

Windows XP users should do the following:

• 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 on 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 directlyconnected. 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:

Windows 95 / 98 / Me users should do the following:

Start > Programs > MS-DOS Prompt

Windows NT / 2000 users should do the following:

Start > Programs > Accessories > Command Prompt

Windows XP users should do the following:

Start > Programs > Accessories > Command Prompt

Step 6 Verify that the PCs can communicate

a. Test connectivity from one PC to the other through the switch by pinging the IP address of the opposite computer. Use the following command at the command prompt.
C:>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?





PC>ping 192.168.1.1

Pinging 192.168.1.1 with 32 bytes of data:
Reply from 192.168.1.1: bytes=32 time=17ms TTL=128
Reply from 192.168.1.1: bytes=32 time=7ms TTL=128
Reply from 192.168.1.1: bytes=32 time=9ms TTL=128
Reply from 192.168.1.1: bytes=32 time=10ms TTL=128

Ping statistics for 192.168.1.1:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 7ms, Maximum = 17ms, Average = 10ms





Step 7 Confirm the TCP/IP network settings

Windows 95 / 98 / Me users should do the following:

a. Type the winipcfg command from the MS-DOS Prompt. Record the results.


PC>ipconfig

IP Address......................: 192.168.1.2
Subnet Mask.....................: 255.255.255.0
Default Gateway.................: 0.0.0.0

Windows NT / 2000 / XP users should do the following:

b. Type the ipconfig command from the Command Prompt. Record the results.


PC>ipconfig

IP Address......................: 192.168.1.1
Subnet Mask.....................: 255.255.255.0
Default Gateway.................: 0.0.0.0




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