Packet Tracer: Use of the TCP/IP Protocols and the OSI Model
[Adapted from Cisco Networking Academy Network Fundamentals]
Background:
In Packet Tracer simulation mode, you may view detailed information about packets and how they are processed by networking devices. Common TCP/IP protocols are modeled in Packet Tracer, including DNS, HTTP, TFTP, DHCP, Telnet, TCP, UDP, ICMP, and IP. Packet Tracer uses a representation of the OSI model to display how these protocols are used by networking devices in creating and processing packets. The term “protocol data unit,” or PDU, is a generic description of what are known as segments at the transport layer, packets at the network layer, and frames at the data link layer.

This is the same convention that was used in a previous lab assignment and will be used throughout this course.

3. Configure IP addresses, subnet masks, and gateway addresses.
Server
IP addresses are necessary for communicating over a network. Each device on the network must have an IP address assigned to it in order to communicate with other devices on the network. You will learn about IP addresses in more detail in a later module/week. For now, you only need to type in the IP addresses as illustrated.
Click the Server device to open the Configuration dialog. Click the Config tab and enter the Gateway IP address as shown below:

Next, click the FastEthernet0 button on the left and enter the IP address and Subnet Mask as shown below:
(Note that as soon as you enter the IP address and hit the [tab] key, Packet Tracer should automatically fill in the Subnet Mask address for you.)

Close the dialog box. You should now be back at the Logical Workplace.

PC
Click on the PC device to pull up its Configuration dialog.
On the Config tab, enter the information highlighted in the next two diagrams:

Close the dialog box. You should now be back at the Logical Workplace.

4. Connect the PC to the Server using the Auto Connect icon.
The Auto Connect feature was described in Lab 1. You can refer to Lab 1 to review instructions for connecting devices.
