"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

The latest versions of GNS3 (Graphical Interface) doesn't have the option for a catalyst switch.  

There are two options to simulate switches:

1) Use generic ethernet switch provided by GNS3 features:
- dot1q trunk

2) Use 16 port switch module in 3600 or 3700 series router
- more features than in generic switch
- not features like PVLAN or MSTP (not in real life either)
- here is list of missing features compared to catalyst switch http://www.gns3.net/phpBB/topic229.html

Because of the hardware component in switches (ASICs), GNS can't emulate switches like it can routers.
