NX-OS versions via APIC API

[bdbauer]

I'm able to pull the topology using the API GET

https://n.n.n.n/api/node/mo/topology/pod-1.json?query-target=children&target-subtree-class=fabricNode

(after authenticating and getting a cookie, of course)

But the version field is empty. I don't see a way to get the version of our NX-OS switches via APIC REST API. Is this something that can be done via API?

Hi @bdbauer ,

Try topSystem like below:

https://{{URL}}//api/node/class/topSystem.json?query-target=subtree&target-subtree-class=topSystem,eqptCh,firmwareRunning

You will get lots of data back and for each topSystem object you get back you will also get the firmwareRunning object which has a "version" key.
