Configure Aggressive Load Balancing / WLC


Wireless clients can load-balance across APs. To enable this feature you will have to configure Aggressive Load Balancing.

During the association phase, aggressive load balancing is working. If enabled and the conditions to load-balance are met, the association response frames are sent to the client which includes the status code 17.
This code indicated that the AP is too busy to accept more associations.
