yes, should work.

it would be best if both would run same IOS and same feature set(the above mentioned have both ip base).

This didn't work for me -- I tried stacking these two models together, both on the same version of code (

c3750e-ipbasek9-tar.122-58.SE2) but got an error saying that there is a major version mismatch.


Do you have any suggestions?

They must both be running the same version of IOS and they must be the same license level. (IE, they both must be lan base, or ip base, or advanced ip services). As long as the IOS versions and licensing are identical, it's no problem.

Thanks for the replies.  This is embarrassing -- I didn't realize that somehow the license on the 12s-s got blown out:

License Level:

License Type: Default. No valid license found.

Next reload license Level:

which explains why it didn't want to stack.  Too bad there wasn't a log entry that said that -- I'd like those hours of my life back!  Now to figure out how to get a new license code...

Thanks for your replies.
