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. Cisco VIRL has fantastic images which you can download such as: Cisco ASAv Virtual Cisco ASA Firewall Cisco IOSv Virtual Cisco Router Cisco IOSvL2.

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. Download Cisco IOU IOL Images (GNS3 / GNS3 IOU VM / Oracle Virtual BOX / L2 & 元 cisco switch images) Below is the list of all layer 2 and layer 3 cisco switches. 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. IOSvL2 is an implementation of Cisco IOS Layer-2 switching code (based on the DSGS code branch) running as a full virtual machine on a hypervisor. 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. IOSvL2 is an implementation of Cisco IOS Layer-2 switching code (based on the DSGS code branch) running as a full virtual machine on a hypervisor. images (Cisco VIRL images) to run IOSv and IOSvL2 in your GNS3 topologies. In short, they are Cisco IOS images running on Unix and Linux operating systems. 4 (3)S Release Information Configure Cisco IOS Software Cisco IOS Software. First of all, let me briefly explain what IOU (IOS on Unix) is.
