This article is assuming you have other devices downstream before the route10. Additionally the last comment speaks to my point
“My guess is that the key gotcha is that you may need to set the controller URL on the Route10 before it will show up in the controller. Please let me know if you get hung up anywhere on these steps.”
We are trying to help Alta understand that there’s a major miss here for staging a new Route10 and Control with or without existing networking equipment. There shouldn’t be a pre-requisite for pre-existing or active networking equipment to establishing local management of your ecosystem right out the gate. It seems like the responses here are trying to justify the process that may have accidentally been overlooked.
I honestly don’t know of any other way to explain this. I would invite your team to read my post and feature request dating back to February of this year which speaks to this.
