Can anybody tell me which one is the stable latest ios version for teh cisco 3750 x series switches?
i have upgraded all the switches in LAB to 15.2 (4) e9 but i am not sure if i send these switches to production, will it remain stable?

before they were running on 12.2 ios version.

thanks in advance

Thank you for your reply Balaj.

I have tried to upgraded few switcheson 15.2(4) E10 version, but they had given me an error that this device is cisco propriotory and something like this.
All i want is just a stable version in production environemnet. I am not looking for any new features.

Not sure what is that error (if you can post that Logs )  also can you give me the exact model of the device. (as per the original post you mentioned 3750-X)

But we need confirmation, some 3750 E kind of model 12.2.55 SE 12 is a good candidate as for as my last test, there SE13 (not used it ) since environment no longer has 3750 all migrated to Cat 9300. or cat  3850.
