Caveats
•
CSCso27775—The controller logs show several error messages on one line only (both on the CLI
and on the syslog server). The error message is truncated, so it does not reach the carriage return in
the end. This error message appears when several access points are trying to join a controller that is
already at full access point capacity.

•
CSCso30745—When a packet fails the admission control test because the switch fabric cell buffers
corresponding to its stream are full, it is incorrectly forwarded to the CPU instead of being
discarded. This incorrect forwarding of many such packets could cause an overload of the CPU and
a Reaper reset.
