Down APs

Tools like AirWave or AKiPS will discover what APs are on the network and let us know when something goes down. This is good, but it doesn't tell us if the AP is expected to be down, replaced, or if a new AP has never come up. That is, it doesn't capture intent.

ATLAS is the authoritative source for intent and what is expected. The controllers are the authoritative source for what is reality.

Possible discrepancies

A non-exhaustive list of things that could be wrong:

• An AP is down
  • Listed in Atlas
  • Not listed or down on the controller
• Different AP is present
  • MAC does not match
• AP was not removed
  • Not listed in Atlas (at least, not in the list of what is expected)
  • Is listed on the controller

Script

Here is a start to a script that does this comparison. Notably, it does not yet talk to ATLAS. Without real data, it is of limited use, even as a PoC.
