Yes, it seems that all models of c2960 can support at least IOS 15.0 

15.2.x is for X model. that is what you have, right?

since there are several models, make sure you choose correct one - difference in size of RAM and flash storage.

Thank a lot Martin for quick reply. I have various models of 2960 including 2960x.


The release I am trying to go from 12.2 to 15.x.


well, it seems that u can get IOS for older as well as newer X models. Just make sure u upgrade switch model with appropriate IOS version as older models seemed to stop at 15.0 whereas IOS 15.2 is the latest for newer ones.

You can go direct.
Note: There is a possibility of an automatic ROMMON/bootstrap upgrade and this can take up to 20 minutes.

Thanks for precise answer. 


We have a basic SVI configured with default gateway, also ISE authentication is enabled on some of the ports(Mab commands). is there any configuration change ? 


Also you mentioned Rommon upgrade, do I have to use same .bin file or .tar file ?

No changes necessary.
If you want to get the upgrade done right, use the TAR file. To push the firmware to the switch:

archive download-sw tftp://TFTP_IP_ADDRESS/IOS_filename.tar
