I have a Catalyst 3560X (WS-C3560X-24P-S) running the latest IOS 15.2(4)E9 image, however the bootloader is 12.2(53r)SE2.
ROM: Bootstrap program is C3560E boot loader
BOOTLDR: C3560E Boot Loader (C3560X-HBOOT-M) Version 12.2(53r)SE2, RELEASE SOFTWARE (fc1)
I have upgraded 3560/3750G/E/X's previously and have seen the microcode updates that take ages. I assumed the bootloader would be upgraded if needed when the IOS image was upgraded.
I have just been working on a couple of Catalyst 3560X's running older IOS 12.2(55)SE10, however these both a have a newer bootloader:
ROM: Bootstrap program is C3560E boot loader
BOOTLDR: C3560E Boot Loader (C3560X-HBOOT-M) Version 15.2(3r)E, RELEASE SOFTWARE (fc1)
The hardware revisions for the switches are different so I am assuming the one I have that is running the latest IOS was actually manufactured before the other two (V04 vs V07).
I have had a search but can't find any references to updating the BootLoader independently of the IOS image - all the release notes just say the bootloader might get upgraded if needed.
I have unpacked the 15.2(4)E9 and the 15.2(1)E1 tar files and compared them and the 15.2(1)E1 includes the file 'pucode_bundle.dat' file that the later image doesn't. Is this the bootloader? Is there a process for upgrading this independently of the IOS image? The 'archive' command has a 'download-ucode' option?
