    Configuring Packet TracerScenarioIn this lab, you will have the opportunity to configure a virtual lab environment from scratch in the 1

    Up to this point, when Packet Tracer has been used, a data file has been provided for you. In this lab,

    you will create a simulated environment to mimic the configuration of our physical lab environment.

    Devices

    Open Packet Tracer (Start - Packet Tracer). A new, empty file should open. At the bottom of the screen, click the icon for Switches:

    You will need THREE (3) switches in our environment so drag three 2960 switches into theworkspace. The exact location doesnt matter, but it will help if you spread them out in a similar

    fashion to what is shown in the topology diagram.

    Click the icon for Routers:

    You will need ONE (1) router in our environment so drag one copy of the 1841 router into theworkspace. You will want one switch to the right of the router and two switches to the left of

    the router.

    Click the icon for End Devices:

    You will need FOUR (4) workstations and TWO (2) Servers. Drag the appropriate icons to theworkspace. One server will be on the right side of the router and the rest will be on the left side

    of the router (see the topology diagram).

    Arrange the icons neatly as shown in the topology diagram. Save your workspace with a file name ofC1-L8-yourlabtime-yourfirstname-yourlastname.pkt.

    For example, C1-L8-1030-Al-Fencl.pkt. You may save this on the desktop if youd like.

    ConnectionsYou now need to connect your devices together.

    Click on the icon for Connections:

    You will need to use a Copper Cross-Over cable to connect the Station switch and the Classroomswitch. Click on the icon for Copper Cross-Over (a straight dotted black line).

    o Click on one of the switches on the left of the workspace (for example, the stationswitch). A dialog box will appear asking which port you would like to connect this end of

    the cable to. For our purposes, all the FastEthernet ports on the switch are the same so

    you can pick any port.o Click on the other switch on the left side of the workspace. Again you will be asked

    which port you would like to connect the cable to; again you can select any FastEthernet

    port.

    You will need to use a Copper Straight-Through to connect the end-node devices (PCs, Servers,and Routers) to the switches. Click on the icon for Copper Straight-Through (a straight, solid

    black line).

    o Click on one of the end-node devices on the left of the workspace (for example, one ofthe PCs). A dialog box will appear asking which port you would like to connect this end

    of the cable to. Your only valid choice on a PC or Server will be the FastEthernet port;

    on the router, you would have the choice of FastEthernet0/0 or FastEthernet0/1.o Click on the switch you want to connect the device to. Again you will be asked which

    port you would like to connect the cable to; again you can select any FastEthernet port.

    Repeat the connection of Straight-Through cables for all the other PCs, Servers, and Router.Note that the router will be connected to two different switches.

    Resave your workspace!At this point, you should have all your devices connected in a fashion similar to that shown it the

    Topology diagram.

    Configure the ServersWe have two servers in our simulation. The server connected to classroom switch (on the left side in

    the Topology diagram) will act as a DHCP server providing IP information to the PCs. The other server is

    acting only as a target for pings. Both servers will need to have a static IP address (as well as a subnet

    mask and gateway) configured; the DHCP server will need to have that service configured as well.

    Click the server connected to the switch on the same side of the router as the PCs (the left sidein our diagram). Click the Desktop tab.

    On the Desktop for the server, click the IP Configuration button. Fill in the followinginformation then close the IP Configuration dialog box (Note: do this BEFORE configuring the

    DHCP service below):

    o IP address: 172.17.13.253o Subnet Mask: 255.255.255.0 (NOTE: THIS IS NOT THE DEFAULT)o Default Gateway: 172.17.13.1

    Click the Config tab for the server then click on the button for the DHCP service. In the DHCP window, click the existing Pool Name at the bottom of the screen.

    o In the information for the Pool, fill in the information shown below (and in the figureabove)

    Default Gateway: 172.17.13.1 DNS Server: 172.17.11.16 Start IP Address: 172.17.13.10 Subnet mask: 255.255.255.0 (NOTE: THIS MAY NOT BE THE DEFAULT) Max Number of Users: 30

    o Click Save to store the DHCP pool information.o Close the Server Dialog window.

    Click the server connected to the switch on the other side of the router from the PCs (the rightside in our diagram). Click the Desktop tab.

    On the Desktop for the server, click the IP Configuration button. Fill in the followinginformation then close the IP Configuration dialog box:

    o IP address: 172.17.11.16o Subnet Mask: 255.255.255.0 (NOTE: THIS IS NOT THE DEFAULT)o Default Gateway: 172.17.11.1

    Close the Server Dialog window. Resave your workspace!

    Configure the PCsYou will configure the PCs in your simulation to obtain an address automatically from the DHCP server.

    For each of the PCs, click on the PC icon then click on the Desktop tab. Click on the IPConfiguration button.

    o In the IP Configuration dialog, click the button next to DHCP.o Note: it may take a minute or so for the simulation to obtain an address from your DHCP

    server.

    o Be sure to repeat this for all four of your PCs. Resave your workspace!

    Configure the RouterThe router will need to have its two FastEthernet connections configured with IP addresses.

    Click the icon for your Router. In the Router dialog box, click the Config tab: Click the button for FastEthernet0/0. Fill in the following IP information:

    o IP Address: 172.17.13.1o Subnet Mask: 255.255.255.0 (NOTE: THIS IS NOT THE DEFAULT)

    Click to put a check mark in the box by On in the Port Status; if you fail to do this, theFastEthernet port will not be active.

    Repeat the previous two configuration step for the FastEthernet0/1 interface using thefollowing IP information:

    o IP Address: 172.17.11.1o Subnet Mask: 255.255.255.0o Be sure to activate the port by changing the Port status to On

    Click on the Settings button on the Config tab. Click the Save button next to the NVRAM button to save your configuration on the Cisco Router.

    Failure to do this will cause your configuration to be lost when the router restarts.

    Resave your workspace!

    Test your simulated environmentIf everything has been configured correctly, you should be able to ping the DNS server from any of

    your PCs.

    Open the command prompt on PC0 and type ping 172.17.11.16. If you get time-out messages, check your command for typos and repeat it at least three times. The ping command shouldbe successful.

    o If your ping fails, you will need to troubleshoot your environment.

    Collect and submit your environmentFor grading, you will need to send an email with your Packet Tracer file attached. Be sure the file name

    is in the form ofC1-L8-yourlabtime-yourfirstname-yourlastname.pkt. For example: C1-L8-1030-Gus-

    Goof.pkt. Send the file to [email protected] with the subject line ofCisco1 Lab8.

    DO NOT FORGET TO ATTACH THE FILE!!! You may also want to keep a copy of the file on a USB thumb

    drive if you have it with you. (You could also email the file to yourself if you would like.)

    ReflectionIn this lab you simulated an entire network. Devices were defined, appropriate cables were selected for

    the connections, switches were interconnected using cross-over cables, and multiple networks were

    combined using a router. A DHCP service was configured to provide IP networking information to PCs

    on the local network. A server and the router had their IP address information statically assigned.

    Finally, the ping command was used to test the connectivity in the simulation environment.

    Clean upEnsure your email with your Packet Tracer file has been sent and a backup copy has been saved for

    future reference. When you are convinced you have finished with the file on the lab computer, delete

    the file you created. Unless otherwise instructed, you may shutdown the computer.
