3750X with 12.2, I have the 15.2 firmware, how do I upgrade?


Set up tftp server

Upload new firmware to flash, something like

# copy tftp: flash:

Do this:

conf t
boot system flash:c3750e-universalk9-mz.152-4.E7.bin

Check the value of boot to make sure the new firmware is indicated:

# show boot


# wr me


...wait about 30 minutes, it has a bunch of microcontrollers to flash

When it eventually comes back, check the running version:

# show ver

This is a collection of techical information, much of it learned the hard way. Consider it a lab book or a /info directory. I doubt much of it will be of use to anyone else.
