Non-Native IOU for Windows and OSX

IOU is IOS on Unix. It's a version of IOS compiled to run as a linux program. It's faster and lighter than emulation.

Please note that GNS3 can not provide you images or licences.

Tutorial for 1.3 and before are obsolete the method work but you no longer need to upload images by hand.

GNS3 VM

Since IOU is for Linux you need to use a Linux VM to use it.

At first you need to configure the GNS3 VM read the documentation here.

Licence

You need a licence for your GNS3 VM to run IOU. This licence is provided by Cisco. We called this licence file iourc

The content of the licence file will be like this:

[license]
gns3vm = 42aa42bb42cc84ff;

WARNINGThis is  not a real licence you need to provide your licence. Only Cisco can provide you an IOU licence don’t ask for it on the forum.

Save this file somewhere on your disk.  And the GNS3 preferences put the path of this file in the iourc box.

Add the images

Click on New

And select the GNS3 VM option.

Name your IOU image.

Then click Browse

GNS3 should detect if it's an Layer 2 (Switch) or Layer 3 (router) image.

It is now listed among the IOU Device Templates.  

And could be found in the router and switch section.
