Release Notes for Cisco Wireless LAN Controllers and Lightweight Access Points for Release 3.2.171.6
OL-11567-02
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.

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.

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.
