Some time ago i posted how to convert a ACI switch to NX-OS, now the other way around.
Copy the file to the NX-OS Mode N9k
switch# copy scp: bootflash: Enter source filename: Downloads/aci-n9000-dk9.12.2.1o.bin Enter vrf (If no input, current vrf 'default' is considered): management Enter hostname for the scp server: 192.168.0.5 Enter username: USER Password: aci-n9000-dk9.12.2.1o.bin 1% 15MB 3.8MB/s 04:34 ETA
Change the boot mode to aci
switch(config)# boot aci bootflash:///aci-n9000-dk9.12.2.1o.bin Warning: Please check list of all ACI supported hardware before doing this operation, not all hardware are supported. Warning: Booting to an ACI image will remove all nxos configuration and format bootflash. Do you want to continue (y/n)?[n] y Performing image verification and compatibility check, please wait.... Image verification successful.
That’s it, just boot the switch and you can join the fabric 🙂
Be aware that the first reload can take quite some time! (15minutes+)
switch# reload !!!WARNING! there is unsaved configuration!!! This command will reboot the system. (y/n)? [n] y
Hi Richard, Great to see your article, Appreciate the way you explain. I would like to understand about the L3out in the case of Cisco ACI. I checked one of the article but not sure about any information on Cisco ACI L3out and how we compare the same with VMWare NSX.

Please can you provide some information about it.
Hi Parminder,
An L3out is used to connect to external networks via l3. It’s comparable to the ESG of NSX.
If you have a more specific question, shoot me a mail blog [at] strnad.ch
Cheers

Hi Richard, Thanks for the article, I will however point out that after you reload this switch with the last command, it will boot into ACI, but if you powercycle the switch again, it will go back to the BootROM.
What is required within the aci CLI following the reload command within your article is the following additional commands::
(none)# setup-bootvars.sh aci-n9000-dk9.12.2.1o.bin
(none)# reload
Hi,
Thanks for this note. I don’t think this is required if the switch joins a fabric? Or is it?
Regards
Richard
