Day 1 - Introduction to Packet Tracer

Introduction to Cisco Packet Tracer Link to Introduction to Cisco Packet Tracer

Cisco Packet Tracer is a powerful network simulation tool used for building, configuring, and troubleshooting network topologies. This tool allows you to visualize networking concepts in a hands-on manner.

Overview Link to Overview

In this lab, we will introduce the following objectives:

• Understanding the Packet Tracer interface.
• Learning about commonly used devices in Packet Tracer.
• Setting up a basic DHCP (Dynamic Host Configuration Protocol) example.

Below is a detailed table explaining the different types of cables used in Packet Tracer:

Overview of Interfaces Used in Packet Tracer Link to Overview of Interfaces Used in Packet Tracer

In Cisco Packet Tracer, different types of interfaces are used to connect devices. Each interface type has specific characteristics such as bandwidth, port type, and application. Understanding these interfaces helps in configuring networks correctly.

Below is a detailed table explaining the different types of interfaces used in Packet Tracer:

Main Features of Packet Tracer Link to Main Features of Packet Tracer

Packet Tracer offers several features for beginners and professionals alike:

• Simulation of Networking Concepts: Create a variety of network configurations to simulate real-world scenarios.
• Interactive Interface: The drag-and-drop interface allows easy addition and connection of devices.
• Device Support: Includes various Cisco devices like routers, switches, and access points for practice.
• Real-Time and Simulation Modes: Run your network in real-time or switch to simulation mode to observe data packets.
• Support for Multiple Protocols: Learn about different networking technologies, including DHCP, OSPF, and RIP.
• Learning Resources: Built-in tutorials and labs help you learn networking concepts effectively.

Commonly Used Devices Link to Commonly Used Devices

You will frequently work with the following devices in Packet Tracer:

• Routers: Connect different networks and direct data packets (e.g., Cisco 7200, 1941).
• Switches: Connect devices within a single network (e.g., Cisco 2960, 3560).
• End Devices: PCs, laptops, and servers that send and receive data.
• Access Points: Enable wireless connectivity.

Setting Up a Basic DHCP Example Link to Setting Up a Basic DHCP Example

Steps:

1. Open Packet Tracer: Launch the application and create a new project.
2. Add Devices: Drag a router, a switch, and two PCs onto the workspace.
3. Connect Devices:
   • Connect the router to the switch using a straight-through cable.
   • Connect each PC to the switch using straight-through cables.
4. Configure the Router:
   • Click on the router and select the CLI tab.
   • Enter the following commands to enable DHCP:

     default-router 192.168.1.1
     

5. Configure the PCs:
   • Click on each PC, go to the Desktop tab, and select IP Configuration. Choose “DHCP” to obtain an IP address automatically.
6. Test the Configuration: Use the command prompt in the PCs to ping each other and verify the DHCP configuration.
