If the software images do come from anywhere other than the official Cisco software repository including preinstalled on used gear you really need to check the MD5 signature against the official Cisco version. I don't know of any cases of Cisco taking legal action to enforce their intellectual property rights against a re-seller and I'd be very surprised if they took exception to someone using their software in a "virtual" GNS3 environment. Of course there are dozens of Cisco re-sellers that sell used gear and those that do it the official Cisco way sending the equipment back to Cisco for official re-licensing and charging again for the licensing are obviously at a serious pricing disadvantage.
I expect the automobile manufacturer's lawyer wasn't a software licensing specialist and used a lot of boiler plate text from somewhere else without actually realizing the real implications.
That said, I carefully reviewed the license for the software that makes my car work and it's not transferable either so in some cases buying a used car is just as illegal technically - no court would ever entertain that you did something illegal with regard to software licensing in buying a used car. They are copyrighted material, just like Windows or Office and any other procurement method is Not legitimate.Ä«uying used gear is most often technically just as illegal as grabbing the images from some file sharing site because the licenses are not transferable. And they're available inexpensively or even free. There are a lot of switches, routers, and firewalls out there that, although not the latest, are still quite functional. But, if you're trying to work with a lab setup, consider getting the actual physical gear. If it's for business use like a lab set up within the organisation I'd think it was covered but maybe not suitable for you to take home. I don't know how the licensing works for that. Similarly, if they have any service contracts with cisco, you can just download them from cisco. Please do not be offended if folks here ignore your request for these files. I suspect you could find them over on one of the illegal file sharing sites - but I can not ever advise that - you never know WHAT you might get in addition to the IOS files.
There are others ways for getting them but advising you of that would be against Cisco's legal protection and I do a lot with Cisco and so will not suggest them. Whelton Network Solutions is an IT service provider. To do so, you need to perform the following steps: Step 1. Lab Configuring Switch Security Features.
Lab 02 : Configuring Ethernet and Serial Interfaces. Open the console of the router as shown in the following figure. Right-click on the added router and then select Start to start it. Drag it to the work view area as shown in the following figure. In the GNS3 console, you can see that c router is added. In the WIC modules page, select the WIC modules to add additional modules as per your requirement, and then click Next as shown in the following figure. Select the additional slots, if required, and then click Next as shown in the following figure. In the Network adapters page, ensure that slot 0 is already listed and selected. In the Name and platform window, specify the name and platform for the IOS image and then click Next as shown in the following figure. Click Next to proceed, as shown in the following figure. In this case, e will use Cisco router c IOS image. To do so, you need to perform the following steps.
