I’ve been getting questions about switches in GNS3 so decided to write this article explaining which switching protocols you can or cannot use in GNS3. For CCNP or CCIE. But, can one substitute the 3560 with the 3750 switches in building the CCNP or CCIE labs? Now I want to do my practice in GNS3, but i do not have CISCO.

Hi all, Just starting out with GNS3 and stumbling a bit:) I've read through a few posts and how to's but not yet found answers to all my issues hence my post. 1) Is is possible to simulate a Cisco 3750 switch of do I need to work with the default ethernet switch provided by GNS3? (I have the IOS) 2) When creating a pix from an IOS, I do not see the option to choose that platform: eg platform C3700 model 3725. There is no option to choose a PIX platform.

Hope that makes sense! Greatly appreciate any replies.
