Adding 3750X to 3750G Stack

[scottsassin]

Our customer has a stack of 6 3750G switches.  They want to add another switch to the stack.  I tried to quote another G, but I got a warning that the G series is EOS January 30,2013.  Can I add a 3750X to the stack?  I know that no matter what switch I get, I will have to upgrade the IOS in the stack, as the stack is running 12.2(25)SEE2.

Hi Scott,

yes you can mix 3750G with 3750X switches in a switch stack.

As you correctly pointed out all switches must be in the same IOS release. For the 3750x there is another gotcha as well. By defaulft it comes with a universal image and a LANBASE feature set enabled. If you are on ipbase on the 3750g you also need to buy a ipbase license for the 3750x or else it won't stack with the existing switches.

Please rate this answer if useful.

The "highest" IOS a 3750 with 16 Mb of flash memory can go is the 12.2(55)SE and later.

You will not be able to load 12.2(58)SE and/or 15.0(1)SE.
