Product and Software: This article applies to all Aruba controllers and ArubaOS 3.x.
"N/A"refers to FQLN. When ArubaOS is upgraded from 2.x to 3.x, if the APs are not provisioned in 3.x, it is possible that "N/A" appears to indicate that FQLN has not been mapped yet.
"?/?" refers to Slot/Port. The question marks will show the slot/port of the up-link as access/trunk. If the link is down, slot/port will be blank space. This is normal if the AP is operated as an AM or "Inactive".
