3750 on Stack

[cris_jimenez]

Hello,

I'd like to know if Cisco supports multiple images on a 3750 on stack

if it's supported we'd like to load

ip services on the core switches (2 switches)and ip based on the remaining switches 4

if that is supported could you please provide a link that will show us how to do you upgrade of the images on the stack

thank you

I do not believe that it is supported to do what you suggest in running different images of members of the stack. In the stack all members must run the same image. If a switch is not running the same image as the master then the switch will not become an active member of the stack.

Believe it is, but much depends on how the images differ.

"ip services on the core switches (2 switches)and ip based on the remaining switches 4

Believe you could. You could flash each switch independently, and with compatible versions, stack them. Or you could flash one stack of two and one stack of four and join them. What's the problem, don't believe you can easily flash the combined stack of six and have two different images. (On-going upgrade headache.)

Below are two references to 3750 stack management.

PS:

Believe the rules of different feature sets within a stack are different for the 3750-E series.
