  My First Packet Tracer Lab Introduction Welcome to Packet Tracer. Research has shown that users who master a few basic tasks when first starting to use Packet Tracer get much more out of the software. This lab is designed to familiarize a user with Packet Tracer's features. This activity should take approximately 30 minutes to complete. Use these directions to go through the lab yourself, or view the animated tutorial version of the lab. Lab Objectives Important Terminology 1.ICMP ping: command consisting of an echo request message from one device to another, and the returning echo reply. 2.IP address: 32-bit address assigned to devices as identification in the network. 3.Ethernet: one of the most common LAN standards for hardware, communication and cabling. 4.Fast Ethernet Interface: 100 Mbps Ethernet port. In Packet Tracer, a GUI may be used to configure such interfaces. 5.OSI model: 7-layer framework for looking at network protocols and devices, consisting of the application, presentation, session, transport, network, data link, and physical layers. 6.PDU: protocol data unit, a grouping of data appropriate to a given layer in the OSI model. 7.Packets: OSI Layer 3 protocol data units. Represented by envelopes in Packet Tracer Simulation Mode. 8.Device Tables: includes ARP, switching, and routing tables. They contain information regarding the devices and protocols in the network. 9.ARP Table: Address Resolution Protocol (ARP) table, stores pairings of IP Addresses and Ethernet MAC addresses. 10.Scenario: one topology with a set of PDUs placed in the network to be sent at specific times. Using different scenarios, experiment with different combinations of packets using the same base topology. I. Viewing Help and Tutorials (View Tutorial) 1.Launch Packet Tracer. 2.Open the help content by clicking Help > Contents on the Menu bar. You can also click the question mark on the Main toolbar. Another option is the F1 shortcut key. 3.The menu will always be visible on the left side of the window while browsing through the help files. Skim through the help sections to get an idea of the functionality of Cisco Packet Tracer. 4.The What's New section under Introduction provides an overview of features that have been added to Packet Tracer. 5.Pay close attention to the Interface Overview section under Getting Started to familiarize yourself quickly to the Packet Tracer interface. 6.Browse the Tutorials section as well. 7.Open the Interface Overview tutorial to learn the basics of the Packet Tracer graphical user interface.

Then click Pause again. Click the Back button to view the previous caption. 10.Continue viewing the tutorial by pressing the Play button. Parts of the tutorial can also be skipped by dragging the slider to the right. If needed, click the Rewind button to restart the tutorial. 11.Click Exit to close the tutorial window. Close the help content as well. Congratulations on learning more about resources that will help you get the most out of Packet Tracer. II. Creating a First Network (View Tutorial) 1.Start creating a network by first selecting the End Devices. Add a Generic PC and a Generic Server to the workspace. 2.Under Connections, select the Copper Straight-through cable (solid black line) and connect the Page 2of 10My First Packet Tracer Lab05/10/2011file:///C:/Program%20Files/Cisco%20Packet%20Tracer%205.3.2/help/default/myFirstPTLab....  devices with it. The red lights on the link indicate that the connection is not working. Now, use the Delete tool to remove the Copper Straight-through cable, and use a Copper Cross-over cable (dashed line) instead. The lights should turn green at this point. If the mouse pointer is held over either devices,the link status will be shown as “Up.” The network should look similar to this: 3.Click on the PC. While paying attention to the link lights, turn the power on, off, and on again. Follow the same steps for the server. The link lights turn red when the device is off. This means that the link isdown or is not working. The link lights turn green when the device is turned back on. 4.Try all three ways to learn about the devices. First, mouse over the devices to see basic configuration information about them. Second, click on each device with the Select tool to show the device configuration window, which provides several ways to configure the device. Third, use the Inspect tool to view the tables the network device will build as it learns about the network around it. In this example, open the ARP table. Since the devices have not been configured yet, the ARP tables are empty. Always remember to close the windows after viewing them or they will clutter the workspace. 5.Open the PC configuration window and change the settings using the Config tab. Change the display name to Client and set the DNS server to 192.168.0.105. Under Interface, click FastEthernet and set the IP address as 192.168.0.110. Packet Tracer automatically calculates other parameters. Make sure that the Port Status box is checked. For future reference, note that other Ethernet interface settings, such as bandwidth, duplex, MAC address, and subnet mask can be modified using this window.   Page 3of 10My First Packet Tracer Lab05/10/2011file:///C:/Program%20Files/Cisco%20Packet%20Tracer%205.3.2/help/default/myFirstPTLab....  6.Go to the Desktop Tab and click on IP Configuration. Notice that the IP address, subnet mask and DNS server can be changed here as well. 7.Open the Server configuration window and go to the Config tab. Change the display name to Web Server. Click FastEthernet and set the IP address as 192.168.0.105. Make sure that the Port Status is also on. Click DNS and set the domain name as www.firstlab.com. Set the IP address as 192.168.0.105 and click Add. Finally, check to make sure that the service for DNS is on. 8.Reposition the network devices by dragging them to a new location. Add a network description by using the “i” button on the upper right corner. Then add some text labels within the Logical Workspace by using the Place Note tool. 9.Load a background grid using the Set Tiled Background button. 10.Save your work using the File > Save As option and create a meaningful filename. Congratulations on creating your first network. III. Sending Simple Test Messages in Realtime Mode (View Tutorial) 1.Start by opening the file saved in the last section. 2.Notice that the file opens in Realtime Mode. Use the Add Simple PDU tool to send a simple one-time  ping message, called an echo request, to the server. The server responds with an echo reply because all devices have properly configured IP address settings. 3.Scroll up and down the User Created Packet Window to see the different capabilities of this ping message, including an indication that the ping was successful. 4.Toggle the PDU List Window to see a larger display of this message. One or more of these messages can be saved as a scenario. Scenario 0 is displayed when starting. Label this first scenario with an “i” note. Different scenarios allow the use of the same topology for experiments with different groupings of user created packets. 5.Click New to create a new scenario. New scenarios will initially be blank. 6.Add two packets using the Simple PDU tool, a PDU from the PC to the Server and a different PDU from the Server to the PC. Then add an “i” note describing the scenario, to complete Scenario 1. An example is shown below: Page 4of 10My First Packet Tracer Lab05/10/2011file:///C:/Program%20Files/Cisco%20Packet%20Tracer%205.3.2/help/default/myFirstPTLab....  7.Several scenarios can be saved with a single network. Alternate between Scenario 0 and 1. 8.Now, remove Scenario 0 using the Delete button. 9.Scenario 1 is now visible. Go to the last column in the User Created Packet Window and double-click (delete) to remove a PDU. 10.Delete the whole scenario. Notice that the scenario list went back to the default Scenario 0. Congratulations on being able to send and organize simple test messages in Realtime Mode. IV. Establishing a Web Server Connection Using the PC’s Web Browser (View Tutorial) 1.Open the file saved from the previous section. 2.Click on the PC to view the configuration window. 3.Select the Desktop tab, and then click Web Browser. Type in www.firstlab.com as the URL and click the Go button. The Packet Tracer welcome page, shown below, appears, indicating that the web connection has been successfully established.
