Stack 2 C9500s with C9300, and what license is needed?

[DSterling]

I have 2 C9500 48Y4C switches and 1 C9300-24 switch. 

Can I stack the C9500s with the C9300? 

What license is required to stack these switches? 

Do all the switches have to have the same IOS and license? 

Thank you,

Hello @DSterling ,

you can only stack C9500 with C9500. The same applies for C9300 - the stacking is done with dedicated stacking cables and only between C9300.

Here are some reference links:

Look at the begining of eachi document to see the Prerequisites and Restrictions for stacking.
