What is Cisco Packet Tracer?

Cisco Packet Tracer is a network simulation program that allows students to examine and experiment with how networks work.

This world-renowned utility has been developed to provide a network simulation tool that can detect the sending and receiving of packets, configuring network devices, and many functions of the network world.

It is represented as an important part of learning complex technology concepts and enables the visualization, design, and simulation of network devices in the application of theoretical knowledge acquired in Cisco Networking programs. It is a basic program for the development of creativity, decision making, criticality, and problem-solving.

Packet Tracer encourages application, discovery, and troubleshooting, enabling students to build a network of almost unlimited devices. A simulation-based learning environment helps students develop decision-making, creative and critical thinking, and problem-solving skills. Packet Tracer includes the Networking Academy curriculum, which allows teachers to easily launch and demonstrate complex technical concepts, as well as design networking systems.

This will help us avoid errors or know how to implement network services such as DNS, DHCP, and Web in the real world, as it provides the tools to configure participating teams on the network, such as Switch, Router, Servers, when creating and emulating a network in Packet Tracer.

Cisco Packet Tracer Features

The current version supports basic routing with RIP, OSPF, and EIGRP as well as a number of simulated application layer protocols.

Although it provides a simulation of functional networks, it actually uses only a small portion of all the features available on the actual hardware running an up-to-date version of the Cisco IOS.

The concept of Packet Tracker is not suitable for simulating production networks because CCNA and CCNP students use it for laboratory simulations.

What Does It Do?

  • Provides a visual representation of complex technologies and configurations.
  • Allows personalized author instructors with guided activities that provide immediate feedback using the Activity Wizard.
  • The courses make it easy to learn many activities, such as individual and group laboratory activities, assignments, assessments, games, network design, troubleshooting, modeling tasks, case studies, and competitions.
  • Provides detailed modeling, visualization, animation and exploration, experimentation and description.
  • Supports self-learning outside the classroom.
  • Supports social learning processes by enabling collaboration and competition.

It supports most of the protocols and technologies taught in the Network Academy curriculum: Cisco CCNA Discovery, CCNA Discovery and CCNA Security and IT Fundamentals, and Cisco CCNP courses can be used to teach concepts.


Some of the advantages of using Cisco Packet Tracer include:

  1. This utility has the ability to simulate, visualize, author, evaluate and control networks and peripherals.
  2. Simulates all functions and features of physical equipment.
  3. It has two workspaces called logical and physical, the difference is that in the logical workspace it will be possible to design and create logical network topologies by connecting or grouping virtual network devices in the physical workspace. The graphical physical dimension of the logical network we create provides a more realistic view of how we need to position or configure the network devices to be used, such as routers, switches.
  4. Packet Tracer combines various geographic locations of networks. We can visualize cities, buildings or cabling cabins for more integration into what networks actually are.
  5. Packet Tracer offers two display modes: real-time mode and simulation mode; As the name suggests, if we use real mode, each of the components we configure and integrate will respond instantly in real-time. However, if we use the simulation mode, we can see details such as control of time intervals, data transfer, or more aspects of the impact on a real network.
  6. Integration of modular devices that simulate hardware to make physical configurations.
  7. It has a multi-user peer-to-peer mode where it is possible to manage virtual networks over a real network.
  8. We have an integrated function and an assistant.

An application that allows you to create or design network topologies, configure devices (data link layer and OSI network layer), add packets, simulate the network, and observe how they work, PT supports the following protocols:

HTTP, Telnet, SSH, TFTP, DHCP, DNS, TCP / UDP, IPv4, IPv6, ICMPv4 and ICMPv6, RIP, EIGRP, OSPF Multitasking, static routing and path redistribution, 802.3 and 802.11 Ethernet, HDLC, Frame Relay and PPP, ARP, CDP, STP, RSTP, 802.1q, VTP, DTP and PAgP.

The PT allows the topology to access each device and configures it as it does in real equipment with a very intuitive graphical interface or console equipment interface (CLI). The PT is flexible enough, so simulated PCs in topology have a desktop where you can access the applications we use on the network every day. You can also add PC servers running services such as HTTP, DNS, and TFTP, which you can connect to the network to simulate operations from the scanners of client computers or to save network equipment configurations.

For example, you can watch the video below to install it on a Windows computer.
