2960S BOOTLDR image different from boot image

Hi Amit,

BOOTLDR version may differ from IOS version. When you flash new IOS image so it depends on previous version and then it is decided if upgrade booloader or not.

Hi Amit,

What Jan is telling you is that the bootloader and IOS version generally do not match because the bootloader update is performed only infrequently, and is in complete control of the IOS image that is being booted. Upgrading IOS in general does not affect the bootloader. Only if the IOS image being booted detects an older bootloader than the one bundled within the IOS image, it will update it. So in other words, the bootloader that comes with 15.0(2)SE2 is exactly the one you see installed, and there is no newer bootloader available.

Best regards,

you don't need other image files on your flash. Just in case you want backup image. You have enough space to have both images on your flash.
