Catalyst 9120 access point

Maurice Ball — Mon, 05 Jul 2021 19:54:49 GMT

I am super smart, so I wrote erase the NVRAM on my Catalyst 9120 access point.

Could someone please provide me with the commands or where to find the instructions on how to install the OS image back on the access point?

Is the AP in u-boot?

If it is, console into the AP and reboot. Post the entire boot-up process.
We want to see with partition the AP is booting.

Cool. That's is helpful.

Do the following:

setshenv BOOT part1
saveshenv

NOTE:
If the commands "setshenv" and "saveshenv" do not work, then use "setenv" and "saveenv".

Re: Catalyst 9120 access point

Maurice Ball — Wed, 16 Dec 2020 07:46:33 GMT

I was not able to enter the commands you provided but I was able to set the following commands listed below. I rebooted the access point after entering the commands but it is still stuck in the u-boot process.

u-boot> env set ?
u-boot> env set BOOT part1
u-boot> env save
Saving Environment to SPI Flash...
Erasing SPI flash...Writing to SPI flash...done

By the way thanks very much for the help.

The commands entered are incorrect.

Re: Catalyst 9120 access point

But what do the boot logs show after setting that?

Re: Catalyst 9120 access point

Maurice Ball — Wed, 16 Dec 2020 18:42:27 GMT

The same as before. Don't we need to copy the OS back onto the flash drive?
