To install GNS3 on macOS Sierra / macOS High Sierra operating systems, please see the article below. You can watch the video below to install GNS3 on your Windows computer and also subscribe to our YouTube channel to support us!Īs mentioned above, you can install GNS3 network simulator on Linux systems (Ubuntu, Debian, Linux Mint).įor example, to install GNS3 on Ubuntu, click on the image below to browse our article. The program runs based on the hardware performance of your computer.You need to manually add the Router/Switch images you download.(You can download it from and purchase a VIRL license). IOS images are downloaded by the user.Large and active community (more than 800,000 members).No need for additional virtualization software.( Virtualbox, VMware Workstation, VMware Player, ESXi, Fusion). Supports both free and paid hypervisors.Supports all VIRL IOS images (IOSv, IOSvL2, IOS-XRv, CSR1000v, NX-OSv, ASAv).Supports multiple switching options (ESW16 Etherswitch, IOU / IOL Layer 2 images, VIRL IOSvL2):.

There is no limit to the number of supported devices (only the limitation is your hardware: CPU and memory).AdvantagesĪfter making the GNS3 definition, let’s examine what the advantages are. IOU Devices → A real Layer2 and Layer3 Switch lets you use all the features of your network device by adding an IOS image. VirtualBox VMS → VirtualBox Virtual Machines → Including virtual machines in topology with VirtualBox. VMware VMS → VMware Virtual Machines → Including virtual machines in topology with VMware Workstation. VPCS → Virtual PCs (Virtual Computer) → Adding a virtual computer. Wireshark (Old Name: Ethereal) → Network Monitoring / Listening to Network (Win)Pcap → Packet Capture Library (Driver for Sniffer) Pemu → Cisco PIX Firewall Emulator Based on Qemu Network Simulator Program Termĭynagen → Beginning Front End for Dynamips You can set the Idle-PC value when adding a device to the program. This simulator software uses IDLE-PC Value to show better performance of Cisco Routers or Switch IOS and shows you the optimal value with * character. As a result, you can run and use a real Cisco Router on your computer with GNS3. Other software includes network devices such as Routers or Switches. What Does GNS3 Do?Ĭompared to other network simulator programs (RouterSim, Boson NetSim), you can use Cisco IOS images more specifically with the back-end Hypervisor software through this network simulator program. This software not only supports Cisco devices but also supports the Juniper, MikroTik, Arista , and Vyatta network devices.Īs an alternative to this program, you can also use the Cisco Packet Tracer program developed by Cisco Networking Academy.
