If there is no license file, go to the next step. Run the following commands to check the presence of the license file in the GNS3 Server root folder. Since the distribution of IOU images is prohibited, we have hidden some points during the licensing process. You will need a license file to upload an IOU image to the GNS3 server. On the Shell (Open a console) option, press Enter. Make a note of the IP address of the server and press the Enter key on the OK option to switch to Advanced Setup. The first boot view of the GNS3 VM server is as follows. Once the GNS3 OVA added to the virtual machine, run the VM. Please wait while importing the GNS3 VM OVA file.
Double-click the setup file to start the installation.Īfter running the VMware Workstation program, click the Import button to add the GNS3 OVA file to the virtual machine.
Once you have the necessary tools, the first thing you do is to install the GNS3 VM. How to Add and Run IOU Images on GNS3 ServerĪfter briefly discussing what is IOS on Unix and GNS3 VM, let’s examine how to upload and use an image onto the server. Together with the development of the program, they provided for a solution due to Dynamips’ high resource usage while creating network designs and running GNS3 Server on the virtual machine, resulting in less resource usage. In the early stages, GNS3 only simulated Cisco IOS images with Dynamips. Our recommendation Inserting a high-speed SSD drive into the USB 3.0 external drive box makes it healthier and more efficient to use. In addition, the GNS3 VM virtual machine installed on an external drive provide more performance.Īdditionally, you don’t have to fill your computer’s disk capacity with Cisco images and GNS3 projects.
The biggest advantage of using this image is the ability to design more complex networks than Dynamips. In addition, as this structure is designed by Cisco employees for experimental purposes, it is strictly prohibited to distribute and reproduce these images to customers or any platform. While Dynamips simulates the Cisco Router and Switch devices, you can add the same devices in the IOU structure. IOU functions are similar to Dynamips but use fewer resources. In short, they are Cisco IOS images running on Unix and Linux operating systems. First of all, let me briefly explain what IOU (IOS on Unix) is.
