Nope, that was all working, but it was highly confusing. I heard back from support:
“Unfortunately this is a known issues with Cloud IQ itself, we already have a high priority ticket in with our dev team. However there is no ETA for a resolution yet.
The behavior is that after pushing the new static IP, Cloud IQ will begin to display the previous IP information after. If you don't update again (after the UI reverts) the new static you are trying to set should still be in the CLI.
It seems like removing and re-adding the AP to inventory resolves the display issue at least temporarily. However I have hear the issue can recur even after doing this process.
“
Glad to know I wasn’t going insane.
