1. Cisco IOS images for Dynamips GNS3 offers multiple ways to emulate IOS. For older images, we use and maintain Dynamips; an emulator dedicated to emulate some Cisco hardware. Dynamips can run unmodified IOS images.
2. In Gns3 by default there is no way of running Cisco switch, but using Cisco 3640 IOS image you can convert your router into switch. There is a module i.e. NM-16ESW module which can be used with Cisco 3640 IOS in gns3 and provide you the switching features in GNS3. There are many cisco images which supports NM-16ESW-module, such Switch IOS.
