CSCse64027—LWAPP-enabled IOS access points joined to a controller running software release
3.2.150.6 or 4.0.155.0 may disconnect and reconnect every 120 hours when the access point's
heartbeat timer is set to the default value of 30 seconds. When the heartbeat timer is set to a smaller
value (such as 10 seconds), the disconnect occurs more frequently (such as every 40 hours). While
the access point is disconnected from the controller, clients are unable to associate to this access
point.
