Overview


This article describes a possible cause and solution for scenarios where discovered devices are placed in the Unplaced Devices folder for no apparent reason.


Problem, Cause and Solution


Back to Top

Problem: When running discovery task with 'Resolve topology' option checked, discovered devices fall into 'Unplaced Devices' folder. Network topology may also not resolve properly.

Possible Cause: Failed SSH logins will always place devices in the Unplaced Devices folder since no information was obtained to determine device's actual position in the topology.

Recommended Solution: Verify that the SSH settings are correct and that port 22 is open.

NOTE: If there are many failed SSH logins, there might not be enough network information to reduce topology-position for devices in which airControl did log in successfully. Make sure airControl can successfully log into each discovered device via SSH, since this is crucial for correctly resolving topology. Correct network topology is also very important when performing firmware updates in a PoE-safe manner.
