Cisco Packet tracer is a network simulator and visualization tool designed by Cisco Systems that allows Cisco networking Academy Students and instructors to create and imitate modern computer networks.
Cisco Packet Tracer is a powerful simulator and it’s getting better from time to time.
With this simulator you can simulate configurations on Cisco Routers and Switches using a simulated command line interface.
You can use Packet Tracer to simulate router features like OSPF, EIGRP, HSRP, DHCP Server and so on.
Or, switching features like VLan, VTP, Port-Security, Spanning Tree Protocol and so on.
How It Works
Packet Tracer uses a drag and drop mechanism to allow users to add and remove networking devices on their projects.
You can use that mechanism to drag and drop networking devices like Routers, Switches, Cables, Cell Towers or even Tablets.
Packet Tracer is so realistic that you have to turn off the device before upgrading or downgrading devices.
Yes, you can upgrade or downgrade devices.
For Example you can change a Fast Ethernet port on a server to a Gigabit Ethernet port, or you can add a fiber card to a router and to do that you have to turn off the device.
Why you need it
First of all, there are more options to work with cisco devices like GNS3 or Boson NetSim and you can work with them without any problem.
The main reason people use these software’s is Cisco Certified Network Associate Certification and most of the time people get the contact with packet tracer before knowing programs like GNS3 and NetSim and that happens because Packet Tracer is the tool used on the Academy and of course that makes sense.
Cisco Certified Network Associate or CCNA is a cisco certification divided in two Exams ICND1 which corresponds to CCENT – Entry Level and ICND2 for CCNA and you may start using Cisco packet Tracer in ICND1 – CCENT.
Cisco Packet Tracer is a simulator not emulator
There is a big difference between a Simulator and an Emulator, Packet Tracer is a Simulator and not an Emulator.
GNS3 is an Emulator and not a Simulator, I will post a small article explaining the difference between both.
Where to download it?
Finally, you can download the last version of packet tracer on this link.
Just login to your Netacad account and download the file.
After downloading, just install, login to the App and start simulating.
