Cisco Packet Tracer

Cisco Packet Tracer is a Windows utility designed for modeling computer networks. The main work is performed in a virtual environment, in which modeling and testing is performed. It is possible to emulate the work of various Cisco nodes, including routers and switches. It is possible to check the operability of the entire deployed network infrastructure. There is support for the Wireshark function, which allows analyzing the received packets during testing.

Modeling

To access the program functionality, you need to create or log in to an account beforehand. A password, last name, first name and email are specified. After that, access to the simulation environment and an extensive catalog of training materials is opened. Formation of the local network is carried out in the visual constructor mode. It is necessary to select the necessary equipment from the catalog, place it on the working area, configure and connect it with other nodes. It is possible to choose the type of connection and cable features.

Simulation

The program allows you to configure the parameters of equipment operation. You can specify network mask, IP, operating mode, DNS parameters, gateway and other parameters for different devices. IPv6 and IPv4 protocols are supported. The created configuration can be run for a comprehensive check. If a certain node will not work correctly, a red indicator will be activated next to it, simulating an LED.

Features

• virtual environment for modeling networks of different levels;
• equipment configuration and connection to other nodes;
• built-in catalog of network devices, cables and interfaces;
• instructions and tutorials;
• simulation of the created infrastructure;
• the program can be downloaded free of charge.
