![]() ![]() It is used to create a lightweight virtual PC that supports basic testing and troubleshooting commands such as ping and traceroute. If you want to run GNS3 from a virtual computer, you should use GNS3VM instead of this component. It is used to create a virtual computer and to run GNS3 from that virtual computer. It is used to run GNS3 from the host system. It is used to capture and view data packets exchanged between nodes. If you are installing GNS3 on a previous version of Windows, select WinPCAP. #Gns3 routers windows 10If you are installing GNS3 on Windows 10 or higher, select Npcap. Based on the version of Windows, select either Npcap or WinPCAP. It allows the nodes emulated/simulated on GNS3 to communicate with nodes available outside the GNS3. It connects GNS3 to the host computer's network. The following table provides a brief description of these tools. GNS3 installation package contains several additional tools and components. ![]() Make your choice and click the Next button. If you want to use the default name, no action is required here. If you want to use something else, set the new name. ![]() By default, the wizard uses GNS3 as the start menu folder name. The next screen allows us to customize the Start Menu Folder name. Click the "I Agree" option to accept the license agreement. The next screen shows the license agreement. #Gns3 routers installYou can install GNS3 while other applications are running, but in that case, you have to restart the system before you can use it.Ĭlick the Next button to start the installation. It’s only a suggestion, not a requirement. The first screen of the wizard shows a welcome message and a suggestion to close other applications before starting the installation of GNS3. Upon confirmation, the installation process starts in a wizard. If it prompts, click the Yes button to confirm the installation. It is required when you want to install the GNS3 server on a virtual machine.Īfter downloading GNS3 and GNS3-VM ( if you want to install GNS3 server on a virtual machine), open the folder that contains the downloaded files.ĭouble click the GNS3 client installation file.ĭepending on UAC ( User access control) settings, Windows may prompt for confirmation. #Gns3 routers softwareIf you really want to measure performance on a software based router, you would be best to use a software router, like the Nexus CSR 1000V (seems you might have the hardware to run it) These may help īTW - sorry i misread your results for Case 2.You can download GNS3 and GNS3-VM from the following webpage. And as your figures show, trying to measure throughput is also totally flawed, as you demonstrated by being able to pass more than 100Mb/s through a 100Mb/s interface. But it you want to test QoS, don't bother trying. So if you want to test say that your traffic is getting the right QoS markings, go right ahead. But it does a great job of allowing you to test your Cisco configurations and even connect with "simulators" like VIrtualBox and other emulators like Qemu. #Gns3 routers codeA glorified interpreter, that reads binary code (compiled for the MIPS processor) and finds a way to "emulate" it on your PC (running an Intel or AMD processor).ĭynamips was never designed to or ever claimed to "simulate" a real world scenario. I think 1Mb/s is pretty awesome for what dynamips is - an emulator. I'm not quite sure what you mean by "throughput routing performance is so low". Great work - thanks for the posting, and you are always welcome to link your own articles to this forum when relevant. In the test environment, GNS3/dynamips OUTPERFORMED a physical switch using gigagbit interfaces in a single switch or single router scenario. Result: 123.8164 Mb/s - clearly if this is a physical switch, then it must be using Gigabit interfaces. ~Again 100 times better than two c3725 routers!!! AMAZING - you got more that 100Mb/s through 100Mb/s interfacesĬase 4 - traffic through a physical switch - no specs of switch given (would be nice to know what we are comparing here) ~100 times better than two c3725 routers!!! AMAZING - you got more that 100Mb/s through 100Mb/s interfacesĬase 3 - traffic through just ONE 3725 NM-16ESW switch Case1 - traffic through two c3700 routersĬase 2 - traffic through just ONE 3600 router ![]()
