Whether it's straight-through or crossover copper cables, fiber-optic cables, DCE or DTE serial cables, or crossover console cables, Packet Tracer provides plenty of options for connecting entry-level network devices. What does it look like when a laptop accesses a network through a wireless connection? How is the configuration of an ASA firewall different from an ISR router? Packet Tracer makes it easy to add a device to an existing topology.Ĭonnection Variety. You can even experiment with devices outside exam prep. These network components are invaluable when studying for the CCNA. This is excellent news for anyone using macOS or Linux, but still need a simulator to practice exam topics for entry-level Cisco certifications.

At the time of writing, Packet Tracer runs on most operating systems, including all active Windows operating systems (Windows 7, 8.1, and 10), macOS High Sierra and Mojave, and Ubuntu 14.04 LTS.

The only requirement is that you create and log into Packet Tracer with a Cisco Networking Academy account, which is free to create.Ĭross-Platform Compatibility.

It is completely free to download and use. There is absolutely no cost associated with using Cisco's Packet Tracer. Packet Tracer has a number of benefits as a free Cisco network simulator, including:

The Pros of Packet Tracer Network Simulator Version: This article evaluates the 64-bit option of Packet Tracer version 7. Packet Tracer was originally designed as an educational aid for Cisco's Networking Academy (better known as NetAcad) but is an excellent simulator for anyone pursuing an entry-level Cisco certification, such as the CCENT or CCNA R&S. Packet Tracer is Cisco's visual simulation tool that simulates network topologies comprised of Cisco routers, switches, firewalls, and more.

Simulator software can run on just about any modern computer without worrying about processor, memory, or storage requirements. The key benefit of simulators is that they tend to be extremely lightweight. For this reason, many advanced features (such as DMVPN, Policy Based Routing, and so on) that real network devices are capable of are not present in simulated counterparts. Instead, each network device is a piece of software pretending to be a real network device to the best of its ability.Īs a result, network devices within a simulator are limited to the commands and features programmed into the simulation. The network devices being simulated are not real network devices, and are not capable of passing live network traffic the same way that a real network device could. What are Network Simulators?Ī simulator is a piece of software that, as the name implies, simulates a network topology composed of one or more network devices. Let's begin by diving into the first category of software - simulators. Our intent is to focus on the pros and cons of each particular software, leaving you to decide. We will not give a blanket recommendation as to which particular piece of software is 'best'. However, we will focus as much as possible on the certification exam use case.ĭisclaimer: We won't necessarily pick a winner. Many of these tools can also be used to test networking technologies for deployment in the real world. These are the most popular software for gaining hands-on Cisco lab experience for the routing and switching track certifications. Our analysis focuses on two simulators and three emulators: Let's take a step back and look at the software itself - and drop the horse race.

That's exactly what we're going to look at. Objectively, each piece of software has its own set of advantages and disadvantages. That doesn't make the decision any easier. Similarly, there are camps staked out on the simulator side, too. Someone who primarily uses GNS3 will always claim that it's superior to VIRL, and vice-versa. Whether you've been advised by a coworker, supervisor, or a thread on Reddit, everyone has their favorite simulator or emulator. So, you'll probably rely on recommendations - and everyone has an opinion. Realistically, it's not feasible to test each program individually. (Yes, despite the title, we'll cover both.) And there's no best way to go about making your selection. When studying for the CCNA, CCNP, or CCIE, choosing the right network simulator or emulator can be a tough decision. Editor’s note: On April 8, 2020, Cisco announced that VIRL is being renamed Cisco Modeling Labs – Personal (CML-Personal) - and that the latest version will be released on May 12, 2020.
