Here’s something that came up, we are replacing a few switches and want to replace it will a couple of 3750s and a 3750e in a stack.
The issue was that the 3750e has a different IOS to the 3750s but still must be the same version. After some playing around I found these versions work together.
c3750e-ipbasek9-mz.122-55.SE8.bin
c3750-ipbasek9-mz.122-55.SE8.bin
This is the latest version that the 3750 (v1) supports, it won’t support the 15.0 IOS because the flash isn’t big enough. The 3750e can’t run anything lower than this because its firmware is not compatible.
But this has allowed me to get two 3750s and a 3750e working in the same stack with no problems.
