new to extreme switches , is there anything out there that i can download and simulate a extreme sw

I know this isn't a VM solution, but you can ask for a loaner thru your sales engineer for a demo switch for a set amount of time to have a physical box to learn on.  This was helpful to me when transitioning from eos to xos before our equipment arrived.

We also have EXOS VM's, check out https://github.com/extremenetworks/Virtual_EXOS

If you are looking for EXOS have a look at GNS3. I have used that to simulate them in the past. Some features are not available, but a lot are.
