The commands mentioned here don’t work anymore with newer releases of the Fabric. So I wrote a new post on how to factory reset your Cisco APIC in 2022

If you want to reset one or all of your APIC Controllers to factory default, there is a easy command for that ’eraseconfig setup'

Do you want to cleanup the initial setup data? The system will be REBOOTED. (Y/n):

When your intention is to reset a whole fabric, it’s recommended to reset the switches first:
Reset a ACI Spine/Leaf Switch
If you reset the APIC Controller first, you have to do this step through console afterwards.
