•
CSCse84879—When a primary, secondary, and tertiary controller are defined for an access point
and the primary controller fails, the access point attempts to join the secondary controller even if
that controller is carrying its maximum number of access point associations. The access point that
needs to rejoin a controller never tries the tertiary controller; instead it reboots and attempts to join
the secondary controller repeatedly.
