Cisco Packet Tracer

What Cisco Packet Tracer is

Cisco Packet Tracer is a free desktop tool for practicing networking, IoT, and cybersecurity in a virtual lab without hardware. Simulation Mode lets learners follow data as it moves through a network and analyze traffic, while Physical Mode provides practice setting up a device rack and cables. The tool also supports adding IoT devices, integrating Python code, and practicing network automation. Tutored activities may provide hints, though Cisco says they are available for select courses. Packet Tracer runs on Windows, Linux, and macOS, not on smartphones or tablets. Cisco says learners can enroll in its free Getting Started with Cisco Packet Tracer course to download the latest version. During installation, the application opens a login window and may send users to a browser to sign in to NetAcad. Some advanced features, including multi-user Packet Tracer, require network access. On Ubuntu, Cisco’s installation instructions use the command line with elevated privileges. Cisco directs users to its Trust Center for security, privacy, compliance, and transparency resources.
