Cisco has developed Cisco Packet Tracer e-learning software to enable users to simulate modern computer networks and create network topologies.
Note that the Packet Tracer application is a “simulation” tool unlike, for example, GNS3 or VIRL.
What is Cisco Packet Tracer?
Cisco Packet Tracer is a network simulation tool (as stated above) used for practice, discovery, and troubleshooting designed by Cisco. Cisco describes Packet Tracer as: “A powerful network simulation program that allows students to experiment with network behavior and ask ‘what if’ questions.”
With that said, it is a powerful networking simulator to help networking students achieve an optimal learning experience while gaining practical networking and technology skills to develop their expertise.
It teaches students to create a network on an unlimited number of devices. They can experience troubleshooting without purchasing switching equipment and Cisco routers real. However, you can never use it to replace actual switches or routers.
This simulation-based learning helps students strengthen their skills while improving their critical thinking, problem solving, and decision-making abilities. It provides an interactive and practical way to learn network protocols.
Some use cases of Cisco Packet Tracer
Cisco Certification Exam
Packet Tracer is an essential tool as it helps prepare for networking exams such as Cisco Certified Network Associate or CCNA Routing and Switching. It requires candidates to complete hands-on labs and a virtual environment that simulates a Cisco network.
CCNA is one of the most prestigious entry-level networking certification exams. The CCNA Routing and Switching certification ensures that students have a solid grasp of the underlying networking technologies and that their knowledge is up to date with the demands of modern industry.
This certification remains relevant to the skill sets needed to adopt next generation technologies. Students can apply their book learning to real-life environments.
They can design networks with topology elements such as routers, switches, cable connections, etc. Having the expertise to create and maintain a small to medium network is critical to overcoming this challenge. exam.
Network design
Network administrators use packet tracers to examine “what happens” scenarios in networks that will help them design the network. They can create a topology guide with it. Allows editing features without deleting anything or starting from scratch.
Check for modifications
Professional network administrators can use Cisco Packet Tracer to test network changes before applying them to the actual network.
Before modifying the network, users can test the new topology to decipher whether everything is in order. Once complete and without any errors, they can apply the changes in a real network.
How to download Cisco Packet Tracer?
Cisco Packet Tracer is a free tool available to Cisco Networking Academy members. Non-members of this academy must enroll in one of their Packet Tracer courses. Once completed, you can download Tracer with these steps:
1. Click the “Register to download Packet Tracer” button
2. Sign up for the introduction to Packet Tracer course
3. Complete your registration in Network Academy
4. Launch the course “Introduction to Packet Tracer”
5. Installation instructions are available in the course
main function Cisco Packet Tracer
Packet tracking mode
Cisco Packet Tracer provides two operating modes to visualize network behavior:
1. Real-time mode – Network works like real devices. It provides immediate, real-time response to all network activities.
2. Simulation mode – User can view and control the time period. They can see the inner workings of data transmission and data distribution across networks.
Packet Tracer Workspaces
Cisco Packet Tracer has two workspaces:
1. Logic – Users can create logical network topologies by connecting and clustering virtual network devices.
2. Physical – Provides a special physical side of the logic network. It helps understand the location and scale of devices like routers in real time.
Operation wizard
The Activity Wizard allows users to design their learning activities. They can do so by creating scenarios using instructional text. And finally, they can develop initial and final network topologies as well as pre-designed packages. This wizard also provides feedback and scoring skills.
Multi-user function
Cisco Packet Tracer is an application with networking capabilities. It has a multi-user peer-to-peer mode to enable collaborative building of digital networks on top of real systems. This multi-user feature facilitates incredible competitive interactions and collaborations. People can use it for social interactions, gaming, and studying.
Instruct
Packet Tracer contains some basic step-by-step instructions to teach users about the product’s features. They clarify how to participate in simulations. For in-depth study, there are pre-tutorials available on the Academy connection.
Limitations of Cisco Packet Tracer
The application itself only has some of the features available inside the actual hardware running the Cisco IOS version. It is not suitable for modeling production networks. It has limited command sets, making it impossible to practice all the required IOS commands.
It is only a study aid, not a replacement for the switching equipment or router in fact, as explained earlier.
Epilogue
Packet Tracer can be difficult to grasp when first starting out. However, the more time you spend on it, the more expert you become at troubleshooting and running network simulations.
It is essential that you familiarize yourself with a tool like Cisco Packet Tracer. It is an intermediate step when preparing to monitor an enterprise-class network. For many administrators of this network, Cisco Packet Tracer is a useful learning tool.
When you configure one router in Packet Tracer, it will put you on the path to becoming a highly capable network administrator and troubleshooter. When you aim for a level of expertise, it is better to start with a limited topology and gradually move to more extensive networks.
Good luck!
