The connection between the two PCs will be accomplished using a Category 5 or 5e crossovercable. Locate a cable that is long enough to reach from one PC to the other, and attach one end1-4CCNA 1: Networking Basics v 3.1 - Lab 5.1.12Copyright 2003, Cisco Systems, Inc.to the NIC in each of the PCs. Be sure to examine the cable ends carefully and select only acrossover cable.b. What kind of cable is required to connect from NIC to NIC? _____________________________c.What is the category rating of the cable? ____________________________________________d. What is the AWG wire size designation of the cable? __________________________________Step 2 Verify the physical connectiona.
Plug in and turn on the computers. To verify the computer connections, insure that the link lightson both NICs are lit. Are both link lights lit? ___________________________________________Step 3 Access the IP settings windowNote: Be sure to write down the existing IP settings, so that they can be restored at the endof the lab. These include IP address, subnet mask, default gateway, and DNS servers. If theworkstation 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 onProperties.•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-upConnections folder.•Click ad 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 in this PC.•Click on Properties and click on Use the following IP address.See the example below:2-4CCNA 1: Networking Basics v 3.1 - Lab 5.1.12Copyright 2003, Cisco Systems, Inc.Step 4 Configure TCP/IP settings for the two PCsa.
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.

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.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/IPsettings for both PCs.

A hub is a networking concentration device sometimes referred to as a multiportrepeater. Hubs are inexpensive and easy to install, but they permit collisions to occur. They areappropriate for a small LAN with light traffic.In addition to the physical and data link connections, which are Layers 1 and 2, the computers mustalso be configured with the correct IP network settings, which is Layer 3, so that they cancommunicate.
Since this lab uses a hub, a basic Category 5/5e UTP straight-through cable isneeded to connect each PC to the hub. 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 offand with cabling disconnected.
Work in teams of two with one person per PC. The followingresources will be required:1-4•Two workstations with an Ethernet 10/100 NIC installed•Ethernet 10BaseT or Fast Ethernet hubCCNA 1: Networking Basics v 3.1 - Lab 5.1.13aCopyright 2003, Cisco Systems, Inc.•Several Ethernet cables, which are straight-through and crossover, to choose from forconnecting the two workstationsStep 1 Identify the proper Ethernet cable and connect the two PCs to the huba.
The connection between the two PCs and the hub will be accomplished using a Category 5 or 5estraight-through patch cable. Locate two cables that are long enough to reach from each PC tothe hub. Attach one end to the NIC and the other end to a port on the hub. Be sure to examinethe cable ends carefully and select only a straight-through cable.b. What kind of cable is required to connect from NIC to hub? _____________________________c.What is the category rating of the cable? ____________________________________________d. What is the AWG wire size designation of the cable? __________________________________Step 2 Verify the physical connectiona.
Plug in and turn on the computers. To verify the computer connections, insure that the link lightson the both PC NICs and the hub interfaces are lit. Are all link lights lit? ____________________Step 3 Access the IP settings windowNote: Be sure to write down the existing IP settings, so that they can be restored at the endof the lab. These include IP address, subnet mask, default gateway, and DNS servers.
