Release Notes for Cisco Wireless LAN Controllers and Lightweight Access Points for Release 4.0.217.0
OL-31336-01
Caveats
•
CSCsg29291—If you change the name of an AP1010 that is connected to the 2106 controller, the
AP Name field is not propagated correctly for the beacon within the Aironet information element
(IE).

(IE).
Workaround: Reboot the controller.
•
CSCsg36747—The Clear Counters button on the Controller Statistics page does not clear the
controller’s counters.
controller’s counters.
Workaround: None at this time.
•
CSCsg40594—If you connect an access point on a VLAN other than the management VLAN,
multicast traffic is fragmented by the controller and sent to the access point with LWAPP
encapsulated. Only the IP fragmented packet is received. The first packet is dropped due to the ACL
applied, and the access point reboots after several minutes.

Workaround: None at this time.
•
CSCsg40655—The controller should not use two port numbers for different size packets. When the
controller encapsulates the UDP payload from a multicast packet, it adds two different distribution
ports for small and large packets.

Workaround: None at this time.
•
CSCsg44650—Cisco Discovery Protocol (CDP) does not operate correctly when a 2106 controller
is connected to a 3750 switch. The controller sees the 3750 chassis as a CDP neighbor, but the 3750
does not recognize the 2106.

Workaround: None at this time.
•
CSCsg46430—Bridging information always shows the Hop Count as zero.
Workaround: None at this time.
•
CSCsg55649—Internet Group Management Protocol (IGMP) V3 join reports sent by the client upon
starting a multicast application may be duplicated to one of the controller ports in the link
aggregation (LAG) bundle.

•
CSCsg64309—Roaming fails between hybrid-REAP access points using local switching and web
authentication.

Workaround: This behavior is as designed.
•
CSCsg64815—The traplog for the 2006 controller and the Wireless LAN Controller Network
Module has a very large port number.
Module has a very large port number.
Workaround: None at this time.
•
CSCsg65482—Controllers sometimes drop multicast packets in unicast or multicast mode.
Workaround: None at this time.
•
CSCsg66265—Client WMM states may not update properly. If a client associates to an access point
as WMM capable, disconnects, is changed to non-WMM capable, and finally re-associates, the
controller sends traffic to the client with a QoS header.

•
CSCsg69021—Fast roaming with WPA2+CCKM on dynamic interfaces may not operate properly.
Workaround: None at this time.

CSCsg71421—The show qos profile command does not operate properly. The controller does not
allow any further input after this command is entered.
