If you want to enjoy even more pain, ah trivia I mean, NXOS and NXOS are not the same thing. Read it again. There is an NXOS train for the original 2/5/7K and current kit in that line, and there is another version for the 3/9K new kit from the ACI spin in. They are just different enough that it makes things difficult when you are trying to develop tools for them. Cisco has promised to merge the two for a long time now.
