Test connectivity from one PC to the other through the hub by pinging the IP address of theopposite 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 switch is a networking concentration device sometimes referred to as amultiport bridge. Switches are relatively inexpensive and easy to install. When operating in fullduplex mode, they provide dedicated bandwidth to workstations. Switches eliminate collisions bycreating microsegments between ports to which the two workstations are attached. They areappropriate 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 mustalso be configured with the correct IP network settings, which is Layer 3, so that they cancommunicate. Since this lab uses a switch, a basic Category 5/5e UTP straight-through cable isneeded 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 offand with cabling disconnected. Work in teams of two with one person per PC. The followingresources will be required:1-4CCNA 1: Networking Basics v 3.1 - Lab 5.1.13bCopyright 2003, Cisco Systems, Inc.•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 forconnecting the two workstationsStep 1 Identify the proper Ethernet cable and connect the two PCs to the switcha.
The connection between the two PCs and the switch will be accomplished using a Category 5 or5e straight-through patch cable. Locate two cables that are long enough to reach from each PCto the switch. Attach one end to the NIC and the other end to a port on the switch. Be sure toexamine the cable ends carefully and select only a straight-through cable.b. What kind of cable is required to connect from NIC to switch? _________________________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 switch 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. 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 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:2-4CCNA 1: Networking Basics v 3.1 - Lab 5.1.13bCopyright 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. The default gateway is only required on local area networks that are connected to arouter.ComputerIP AddressSubnet maskDefault GatewayPC – A192.168.1.1255.255.255.0Not RequiredPC – B192.168.1.2255.255.255.0Not RequiredStep 5 Access the Command or MS-DOS prompta.
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 PromptWindows NT / 2000 users should do the following:Start > Programs > Accessories > Command PromptWindows XP users should do the following:Start > Programs > Accessories > Command Prompt3-4CCNA 1: Networking Basics v 3.1 - Lab 5.1.13bCopyright 2003, Cisco Systems, Inc.Step 6 Verify that the PCs can communicatea.

The computer(s) and routershould be preconfigured with the correct IP network settings. Start this lab with the computer(s),router, and the hub or switch all turned off and unplugged. The following resources will be required:1-2•At least one workstation with an Ethernet 10/100 NIC installed•One Ethernet switch or hub•One router with an RJ-45 Ethernet or Fast Ethernet interface or an AUI interface•10BASE-T AUI transceiver (DB-15 to RJ-45) for a router with an AUI Ethernet interface (2500Series)•Several Ethernet cables, which are straight-through and crossover, to choose from forconnecting the workstation and router to the hub or switch.CCNA 1: Networking Basics v 3.1 - Lab 5.2.3aCopyright 2003, Cisco Systems, Inc.Step 1 Identify the Ethernet or Fast Ethernet interfaces on the routera.
Examine the router.What is the model number of the router? _______________________________________________b. Locate one or more RJ-45 connectors on the router labeled “Ethernet0” or “Ethernet1”. Thisidentifier may vary depending on the type of router used; a 2600 series router is shown.
