Replace Cisco 3750 in stack with different IOS versions

Hi,

If you had a problem with Cisco switch , in a stack, and the replacement switch is under a different IOS version you shoud do an upgrade or a downgrade.


In my case i downgraded the replacement switch to the same version of the existing switch:


1. download de 12.2(35) bin image from Cisco ( need Contract for that)

2. copy tftp://192.168.1.198/imagename.bin flash:

3. dir flash

4.boot system flash:/imagefilename.bin

boot system flash:c3640-i-mz.122-10.bin

boot system flash:c3640-i-mz.122-10.bin

boot system flash:c3640-i-mz.122-10.bin

Your switch should boot now with the new downgraded image..

copy tftp://10.1.1.1/iosimage.bin tftp:
