Symptom: This defect refers to the MAPs behaviour when joining a RAP where the RAP is the AP instance of a Mobility Express controller. If the backhaul is on 5GHz and the 2.4GHz band is disabled, the MAP will lose adjacency and will not come back. Both bands need to be enabled in order for the 5GHz backhaul to stay UP.
