Upgrading Cisco 3750 switch stack with bin file
Posts: n/a

does anyone has any idea to go about upgrading the ios for a 3750
switch stack using binary file? Cisco website has only instructions for
using tar file to upgrade. I have tried the conventional way of copy
the new bin file into both flash1 and flash2 and changing the boot
config to boot with the new image. But when I rebooted the stack, only
the master switch is upgraded and the 2nd was not able to join the
stack as the master detected a version-mismatch.
Reason for using bin file instead of tar file is because I do not need
the CMS in our environment.

Any advice will be greatly appreciated.

I haven't upgraded using just the bin file - but it should work the
same... You only have to copy the software to switchA (Master). It is
responsible for automatically upgrading the other switches in that

I think somewhere down the line when trying to manually copy the
software to both switches - something got confused...

fyi - You can use the .tar file and disable the web interface portion
by using 'no ip http-server' in your configuration

Thanks Scott!

Yes, I was expecting the Master Switch to auto upgrade the 2nd switch
after the reboot but it didn't. The tar file includes the CMS which I
feel it is a waste of Flash space if I not going to use it. And also if
I use a tar file, I can't possibly keep both old and new versions since
the flash size is only 16MB.
I believe there should be a way to upgrade it using the binary file
since it is available in the CCO for download.

Anyway, thanks again for your help!
