Stacking 3750g and 3750x

Hi,

I am wondering if someone can help me.

I am trying to stack a 3750g with a 3750x. At the moment they will not stack with their current IOS as the hardware version is mismatched.

According to various posts this is possible as long as the same IOS is in use. The following IOS are currently in use:

3750g     -     c3750-ipbaselmk9-tar.122-55.SE5

3750x     -     c3750e-ipbasek9-mz.150-1.SE3

I have tried to downgrade the IOS on the 'X' to 122-55.SE5 however, i get errors regarding firmware incompatibility.

I am unable to upgrade the IOS on the 'G' to 150-1.SE3, as the size of the IOS image is larger than the available flash (Version 15 IOS for the 3750G (c3750-ipbasek9-mz.150-1.SE3.bin) is 16,074,189 bytes whereas the 3750G has 16MB of flash memory or 15,998,976 bytes total which mean the IOS will not fit).

Has anyone actually stacked these devices successfully? I understand there may be licence implications of upgrading to 15 but at the moment I just want them to stack!

thanks for any help anyone can give

Stacking 3750g and 3750x

Hello Matt,

in order to run the same image a 64 MB flash would be needed on the C3750G as noted in other threads

I'm afraid you cannot stack these C3750G with 16MB flash with the C3750X

Hope to help

Re: Stacking 3750g and 3750x

if its really needed you can downgrade 3750x to c3750e-ipbasek9-mz.122-55.SE5.bin?

so it will be same fature set and same version.

Which errors are you getting? 12.2 SE5 is the only image you can run to stack with the older swtiches.
