compatibility between cisco 3750 and 3750 v2

Hi all,

I would like to confirm if cisco 3750 and 3750v2 can work in a stack?

My cisco 3750 is working on 12.2(37)se while 3750v2 is working on 12.2(50r)se.

I tried to configure the above on a same stack but seem to have compatibility issue and fail to work.

Pls advise, thks in advance.

Hello Don,

They can be stack but I would recommend you try to have them run the same image and feature set:

All stack members should run the same IOS and Feature Set.

Your classic 3750 should have an IOS upgrade to the minimum level of the 3750v2.

Please let us know what IOS you choose so we can advice you if there are any issues.

The "highest" IOS your stack can run (if your 3750 has 16 mb of Flash) is 12.2(55)SE5.

All should have same IOS version.  The don't have to have the same feature set although it's nice if they do but if you're using more than IP Base, does add to cost.
