Hi folks! So I recently ran into this. A question came up regarding buying newer Cisco 3750 X series switches and stacking them with older 3750 non X series switches. People wanted to know if mixing and matching is possible.
I did some research and from talking to other people who have supposedly tried this. The answer I heard is that it might work with some features but will not work with routing features. I have no idea if this is actually true or not but this is what I heard and I figured I’d share it with you folks in the hopes that someone can shed light on this. If someone knows better, please post on this blog with the real information so the rest of us can benefit.
I for one at this point would not want to risk trying this and end up spending money on a brand new switch just to find out it doesn’t work with my old stack.
