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-dk220.127.116.11o.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
aci-n9000-dk18.104.22.168o.bin 1% 15MB 3.8MB/s 04:34 ETA
Change the boot mode to aci
switch(config)# boot aci bootflash:///aci-n9000-dk22.214.171.124o.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+)
!!!WARNING! there is unsaved configuration!!!
This command will reboot the system. (y/n)? [n] y
Some time ago i posted how you can connect to a spine or leaf switch -> Connect to a leaf/spine switch
With the introduction of NX-OS, the syntax changed a bit. You have now first to drop back to the bash shell and then you can attach the switches. Password is still the same as for the APIC.
admin@apic1:~> attach leaf01
This command is being deprecated on APIC controller, please use NXOS-style equivalent command
# Executing command: ssh leaf01 -b 10.127.240.1

Cisco introduced a NX-OS like CLI for the Cisco ACI Solution with release 1.2(1i).
In this post i will demonstrate some of the things that can be achieved through the NX-OS CLI.
There is no safety net, if you issue something like ‘no tenant XXX‘ the configuration is gone!
No commit, warning or similar!
The NX-OS like CLI is the new default if you connect via SSH to the APIC
