Can I make a VSS with a WS-C4500X-16SFP+ and a WS-C4500X-24X-IPB?

I have read that they need  to have the same number of slots (for 4500E), anyway, that would be the case. I have IPBase for both switches.

Thanks for your help,

VSS is available on a Catalyst 4500-X switch and on chassis that support Supervisor Engine 7-E and Supervisor Engine 7-LE.

Note The two chassis must have the same number of slots. However, +E and -E chassis can be mixed.

see table-5-1 in this link:

You probably don't really know what these P/Ns are.

These aren't modular switches and they DO support VSS.

In addition to Reza's post, Sup8E also supports a new type of VSS, Easy VSS.
