Caveats
This section lists resolved and open caveats for Cisco controllers and lightweight access points.
Resolved Caveats in Software Release 3.2.150.10
•
CSCsd23638—LWAPP-enabled access points are able to join a controller running software release
4.0.155.0 but are unable to download the image.
4.0.155.0 but are unable to download the image.
•
CSCsd34445—An AP1230 joined to a controller may show periodic trace backs, indicating a leak
in IO memory.
in IO memory.
•
CSCse58195—When you upgrade from controller software release 3.0.x.x to 3.2.x.x, any access
control lists (ACLs) that were previously configured or applied to interfaces are removed or
disabled.

•
CSCse60203—Cisco Aironet 1100 and 1200 series access points sometimes fail to upgrade from
release 3.2.150.6 to release 4.0.
release 3.2.150.6 to release 4.0.
•
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.

Resolved Caveats in Software Release 3.2.150.6
•
CSCek16101—The Controller Network Module does not have the correct time when it is first
booted up because it does not have a real-time clock. Therefore, it contacts the NTP server during
the initial bootup to obtain the correct time. If the controller cannot reach the NTP server, it
eventually gives up and boots without the correct time. When this happens, access points cannot
register with the controller. The controller must wait for at least one hour before trying to poll the
NTP server again for the correct time.

CSCsb39522—When a user changes the setting from a static IP address to DHCP and the DHCP IP
address is not available, the supervisor loses keepalive, and the WiSM sends a WCP going down
trap. Similarly, when a user changes a static IP address and enters an incorrect subnet on the service
port, the supervisor detects a loss of WCP keepalive, and the WiSM sends a WCP going down trap.
