Packet Tracer - Create a Simple Network

Introduction to Cisco Packet Tracer

Section 1: Build a Simple Network
In this part of the Lab you will create a simple network. You will follow the Packet Tracer Lab instructions for creating a simple network from Cisco that are found after these lab assignment instructions (which are to be turned in on school website after completing the overall lab).
Important NOTES when building your network:
• Be sure to save your work frequently.
• Use the WRT300N Wi-Fi router, the plain home router will cause connection issues.
• Provide the deliverables in your lab report that are indicated in each section.

Follows these lab instructions

Section 2: PDU and Packet Analysis
In this section we will utilize packet tracer and the test network that you created to simulate network traffic using protocols that are common across topologies. You will examine the Protocol Data Units (PDUs) and follow the network traffic as it traverses the OSI model. Protocols such as TCP and UDP will be further examined to parse out packet header information that is important to Cyber Defense. The exercises in this section will help build a foundation for understanding the techniques and technologies used in attacks.
Part 2.1: Simulate Traffic on your Network.
In the packet racer app, go to ‘Help' (the tab to the far right at the top of the app window), and then click on ‘Tutorials'. This will open the Tutorial. Scroll down to Chapter 4: ‘Realtime and Simulation Modes' to get more information on Simulation Mode, which will allow you to become familiar with the tools we will use for this section.
• Open your previously created Packet Tracer Network and ensure that your communications are clean and green (Keep in mind that it can take a minute or two for things to start communicating) Ping the cisco.com server from your PC and the laptop IP to check on your communications.
• Click on Simulation Mode on the lower right and the Simulation Panel should appear. Toggle the PDU view in the lower right as well.
• Review the Simulation settings such as Play Controls and Filters, take notice of the protocols that are available.
• Simulate using the web browser on the PC to browse to the cisco.com site.
• Dissect the protocols and headers in the conversation.

TASKS

(Question) - Explain in 3-5 sentences what a PDU and relate it to your screen shot of the ICMP packet.

(Screen Shot) - Step thru the ICMP (Ping) simulation until you get an ICMP packet to hit the Wireless Router. Post a screen shot showing the PDU information of the ICMP packet, there should be PDU's at the In and Out Layers.

(Question) - In the previous step what layer of the OSI is used to decapsulate the PDU from the Ethernet Frame?

(Screen Shot and Question) - STOP Simulation and go back to Real Time.. Login to the desktop of the PC and run "arp -a" to display the PC's arp cache. Now let's experiment;

Login to the Laptop and find its IP address. (Figure this out on your own)
a. Go back to your PC and ping the laptop's IP address (you need to be back in real-time or have your simulator set to complex mode full open.).
b. (Screen shot) - Run your arp -a again on the PC and provide a screen shot.
c. (Question) - What changed on the arp -a ? Explain in (3-5) sentences what arp does and how this might have changed your arp cache based on the recent ping.

(Question) - In 2-3 sentences describe how the hands-on activities have helped you better understand network basics.

Section 3: Challenge and Analysis
The challenge section is intended to synthesize the work you performed in the previous sections and add a new challenge that is relevant to the Internet of Things (IoT).

Part 3.1 Add Internet of Things Devices (IoT)

Tasks
Using your existing home network add some internet of things devices.
a. Add a Wi-Fi Thermostat
b. Add a Wi-Fi Camera

These types of devices can be found under the "End Devices" and Home Icons in Packet Tracer (PT)
Connect the devices to your router.

Set Static IP addresses as follows;

c. Camera 192.168.0.150
d. Thermostat 192.168.0.151

(Screen Shot) - provide a screen shot of your devices connected to the Home router.

(Screen Shot) - Prove that you can ping the new IoT devices from your PC.
