Cisco 3750 different models in stacked enviroment?

[Jay Girlardo]

Will the c3750e-universalk9-mz.150-2.SE6.bin IOS on a Cisco Catalyst 3750X-48PF-E Switch and
the c3750-ipservicesk9-mz.150-2.SE6.bin IOS on a Cisco Catalyst 3750G-48PS Switch be able work in stacked mode?

For the 3750G switch there is no universal image. Im assuming that having a universal on the X series and ipservices on the G series would equate to each other for the different switch models. Is this correct?

Yes and no.  The universal image on the 3750X needs to have a license active for IP Services features.  It might only be licensed for IP Base.  However, I believe you can run a stack with both IP Base and IP Services members.

It has an ipservice's license on it . See below.

Currently the switch stack is on c3750-advipservicesk9-mz.122-44.SE2. The 3750x is on 15.0(2)SE6.

What will be required to get these to work successfully being stacked? Will the upgrade to the 3750G's to c3750-ipservicesk9-mz.150-2.SE6.bin work? Even though one will be ipservices and one would be universalip?

Again, "universal" image's feature set depends on license.  As you have a 3750X IP Service license, effectively your universal image is an IP Services image.

Also again, you can mix IP Base and IP Services in the stack, but in your case, if you load an IP Services images on the 3750G, your two stack members will both be IP Services.

Yes, if you load the same IOS version on both switches, and they have IP Base or IP Services, they should work together.  (You can also mix different IOS versions, but StackPlus versions need to match - which is best accomplished by using same IOS version.)

BTW, although can mix StackWise and StackWisePlus 3750s, the former will cause loss of some Plus features.
