stacking 3750X with 3750G

[hepartida]

I have one 3750X with C3KX-NM-10GT, I need to interconnect using stackwise to 3750G-24TS.

The 3750X needs IOS 15.0(1) to use C3KX-NM-10GT, and the latest IOS for 3750G-24TS is 12.2.55.

How can I interconnect them using diferent IOS?

Thanks.

You can't stack them together since you can't use the same IOS.

The minimum IOS requirement to enable the C3KX-NM-10GT is 15.0(1)SE.

Check the flash memory of your legacy 3750G.  If you have 32 mb flash, then you need to upgrade the 3750G to this IOS level before you can stack the 3750G to the 3750X.

WARNING:  IOS version 15.0(1)SE and 15.0(2)SE has some CPU bugs that weren't fixed until 15.0(2)SE2.  If you have to use 15.0 IOS then I'd recommend you use 15.0(2)SE2 as this is the better version among the 15.0.
