Question: What does this error message mean: “AM: Inactive AP Detected SSID/AM: Inactive Node Detected”?

 

Product and Software: This article applies to all Aruba controllers and ArubaOS 5.x and later.

 

What do these error messages mean? Should I be concerned about seeing a large number of these messages in the controller logs?

 

The controller is running ArubaOS 5.0.3.0 with AP-105. Only one controller is active on campus, so it is not an issue of one controller seeing APs from another controller.

These logs mean that the listening AP has stopped hearing another AP or client and the "heard" device has satisfied the configured ageout time(s), so it is aging out of our list. This is normal behavior. If APs are spread out, it is possible that an Aruba AP is far enough away from another Aruba AP that it hears frames from it only occasionally.
