Caveats

CSCsc44326—A 4400 series controller running software release 3.1.105.0 may fail to respond to ARP requests for the ap-manager2 interface’s IP address when the ARP request is addressed at the MAC layer to the unicast MAC address of the interface rather than to the broadcast MAC address. As a result, there may be sporadic interruptions in connectivity at ARP refresh time, resulting in the periodic loss of associations for access points associated through the ap-manager2 interface.

CSCsc72899—An access point in REAP mode reboots if packets are being processed in the access point by one task while discovery is occurring.

CSCsd18145—If you disable proxy ARP on the controller, the ARPs still go to the controller CPU.

CSCsd19801—A 4000 series controller sometimes hangs while it is booting up.

CSCsd27529—Static WEP does not operate properly for a REAP access point in standalone mode.

CSCsd54712—An access point may reboot when it is connected to a 2000 series controller and an N900iL handset associated to the access point tries to place a call after the user idle timeout setting has expired.

CSCsd55009—The access point may suddenly lose its connection to the controller. When this condition occurs, the access point periodically sends out DHCP requests, and the access point Alarm LED lights.

CSCsd59700—The default AP1000/1200 settings for external antenna gain are incorrect. The 4000/4100 controller should show this value as “0” but instead shows it as “11.”

CSCsd65251—The Session Timeout parameter for WLANs on the controller GUI may not operate correctly. The value of this parameter appropriately changes to 1800 seconds when you choose the 802.1X option for Layer 2 security; however, it does not return to 0 seconds if you then choose a different Layer 2 security option.

CSCsd76868—When you enable the Rogue Location Discovery Protocol (RLDP) to detect rogues but do not create WLAN ID 1, the controller reports minor alarms when critical alarms should be reported.

CSCsd85859—The Refresh button does not operate properly on some of the controller GUI pages.

CSCsd87382—Bridging functionality for REAP devices is not available on OEM builds of controller software.

CSCsd90392—The idle timeout may not work correctly for an access point in REAP mode.

CSCsd91051—An “Incorrect input!” message appears when you enter the show wlan mobility command in the controller CLI.

CSCsd95992—When IGMPv3 is enabled on the controller, a significant amount of packet loss occurs. The packet loss is even greater when there is an active multicast stream.

CSCsd99725—An access point restarts when you change its mode of operation from urgent mode to REAP mode.

CSCse03869—When AP Authentication Policy is enabled on a 2006 controller, any connected access points may reboot when a client associates.

CSCse11202—WCS logs an “Incorrect WEP Key” error for wireless clients running TKIP.

CSCse14889—The controller does not generate traps for ad-hoc rogues.

CSCse15889—The controller may reboot after running for many days due to a failure with the sshpmReceiveTask software watchdog.

CSCse20190—When the controller is running software release 3.2.116.21, Spectralink phones fail shared key authentication.
