CSCse59150—SVP packets through controllers have inconsistent timing, resulting in poor voice
quality.

CSCse72853—Access points in REAP mode sometimes fail to act independently from the controller
when the controller fails.

•
CSCse78542—When the AutoRF feature causes the controller to select wrong channels for the
country configured, the show ap config 802.11a summary command causes high CPU usage and
eventual reboot of the controller.

eventual reboot of the controller.
•
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.
