Adding AP to OneView map shows controller versus AP
If you edit the map and select File > Add > Device it will show as the AP under the Devices tab but the icon is a switch and it doesn't show the channels.
If you edit the map and select File > Add > APs the icon is correct and shows the channels but it has the Controller it's attached to under the Devices tab.
Extreme Management Center
The APs were modeled in NetSight/Extreme Management Center as Ping Only devices and those devices were trying to be added to the map.
To properly add the APs to the map you will need to edit the map and select File > Add > APs. Select only the APs that were learned from the wireless controller and not the ones modeled as Ping Only devices.
