Based on this link, Cisco ACI is actually based on the Cisco Nexus 9000 family.

The hardware for it is based on the Cisco Nexus 9000 family of switches.


But when Cisco Nexus or IOS do have show version command, why don't Cisco ACI have similar command?

I would like to know more about this device, like model number, software version etc.

What is the right command for Cisco ACI? Probably something equivalent to Cisco IOS show version?

show version command executed on the APIC will display software versions of the fabric elements:

APIC-1# show version

To run command remotely on leaf/spine from APIC, type fabric NODE_ID <command>:

APIC-1# fabric 101 show version

APIC-1# fabric 104-106,202 show version
