This Image was tested with Gns3 1.1 and i hope this will also work fine with the latest GNS3 version as well.įile name: c3745-adventerprisek9-mz.124-25d. Following are the details and recommended setting of Gns3 3745 IOS image for your GNS3 setup. When I read the words 'service support account' I suspect you have to pay for downloading a software update, right Thanks, Lars. I've found different links 'for a service support account' which are broken. If you need the IOS for your real hardware then it is better to Contact Cisco for the latest and best IOS for your device. Is there a student support service contract I can't download IOS images for my router.

Gns3 is one of the famous network simulators and its hot feature is that it can run the real Cisco IOS image, as compared to another network simulator like packet-tracer which performs all functions based on programming. IOS images support different packages like routing, switching, and inter-networking, etc. IOS image is software or Operating System used in most Cisco routers and switches. Or if you have a server, download the CML on the server and make sure the server is able to handle it.Working 3745 IOS download for Gns3 What is IOS image? The only think you need to think about is you need a solid computer with x amount of RAM (the more nodes, the more RAM and storage is required) and storage. You can download bunch of stuff, like Nexus, Fortigate, ASA, routers, switches, servers and so on. You can even download the images and use it offline so it is not that you need to pay $199 every year. You can purchase CML from Cisco website and it will cost you $199/year and I will highly recommend you to invest in it. You also have EVE-NG (which is not Cisco) and I personally have not used it but it’s looks much nicer than GNS3. What I (and most of the people) recommend is Ciscos own virtual lab, CML (Cisco Modeling Lab) that is equivalent to GNS3 but a little bit better.
There are free IOS images but would not recommend you to download those.
