How to Add Simple PDUs in Realtime Mode and Analyze PDUs in Simulation Mode

Here will be a topology you need to analyze and add PDU. So lets start:

Topology Diagram:

A nearly complete standard lab topology is provided as starting point.

DeviceInterfaceIP AddressSubnet MaskDefault Gateway
S1-CentralVLAN 1172.16.254.1255.255.0.0172.16.255.254
PC 1ANIC172.16.1.1255.255.0.0172.16.255.254
PC 1BNIC172.16.1.2255.255.0.0172.16.255.254
Eagle ServerNIC192.168.254.254255.255.255.0192.168.254.253

Learning Objectives:

  1. Complete the Topology
  2. Add Simple PDUs in Realtime Mode
  3. Analyze PDUs in Simulation Mode
  4. Experiment with the model of the standard lab setup


Throughout the course, you will be using a standard lab setup created from actual PCs, servers, routers, and switches to learn networking concepts. In this activity, you will continue learning how to build and analyze this standard lab topology. If you have not done so already, you are encouraged to examine the Help files available from the Help Pull-down menu at the top of the Packet Tracer GUI. Resources include a "My First PT Lab" to help you learn the basic operation of Packet Tracer, tutorials to guide you through various tasks, and information on the strengths and limitations of using Packet Tracer to model networks.

This activity will provide an opportunity to explore the standard lab setup using Packet Tracer simulator. Packet Tracer has two file formats it can create: .pkt files (network simulation model files) and .pka files (activity files for practice). When you create your own networks in Packet Tracer, or modify existing files from your instructor or your peers, you will often use the .pkt file format. When you launched this activity from the curriculum, these instructions appeared. They are the result of the .pka, Packet Tracer activity file format. At the bottom of these instructions are two buttons: Check Results (which gives you feedback on how much of the activity you have completed) and Reset Activity (which starts the activity over, if you want to clear your work or gain more practice).

Task 1: Complete the Topology

Add a PC to the workspace. Configure it the following parameters: IP Address, Subnet Mask, Default Gateway, DNS Server, Display Name "1B" (do not include the quotation marks). Connect PC 1B to the Fa0/2 port of the S1-Central Switch and check your work with the Check Results button to see that the topology is complete.

Task 2: Add Simple PDUs in Realtime Mode

Wait until the switch link lights are green. Using the Add Simple PDU, send a test message: one between PC 1B and Eagle Server. Note that this packet will appear in the event list as something that was "detected" or "sniffed" on the network, and in the lower right as a user created PDU that can be manipulated for testing purposes. 

Task 3: Analyze PDUs in Simulation Mode (Packet Tracing)

Switch to simulation mode. Use the Capture / Forward button to move the packet through the network. Click on the packet envelope, or on the colored square in the Info column of the Event List, to examine the packet at each step in its journey. 

Task 4: Experiment with the model of the standard lab setup

The standard lab setup will consist of two routers, one switch, one server, and two PCs. Each of these devices is pre-configured. Try creating different combinations of test packets and analyzing their journey through the network.


If you have not already done so, you are encouraged to obtain Packet Tracer from your instructor and complete My First PT Lab (available by using the HELP Pulldown Menu and choosing CONTENTS). "
