Release Notes for Cisco Wireless LAN Controllers and Lightweight Access Points for Release 3.2.171.6
OL-11567-02
Caveats
• CSCsd25491—The management IP address of a controller incorrectly sends an ARP request for a
client IP address on a WLAN subnet over the wired interface. The ARP request is not answered
because the management IP address and the client WLAN are on different subnets.
Workaround: None at this time.
• CSCsd34555—The PC350 client adapter is unable to pass traffic when the access point is not in
protection mode.
Workaround: None at this time.
• CSCsd38979—When you set the QoS WLAN parameter to Platinum (voice), Internet Control Message
Protocol (ICMP) requests from the client are not being marked for voice.
Workaround: None at this time.
• CSCsd39873—The controller may report a WEP key encryption error for Intel 2200BG clients
operating with OEM driver version 9.0.1.9, 9.0.2.5, or 9.0.3.9 and using some form of EAP
authentication (PEAP, LEAP, EAP-FAST, or EAP-TLS).
Workaround: None at this time. However, the client will attempt to reauthenticate and upon
successful EAPOL key exchange will communicate in a normal, encrypted fashion.
• CSCsd50369—When radio resource management (RRM) is enabled on the controller, an access
point in monitor mode may not send an acknowledge packet in response to a reassociation request.
Workaround: None at this time.
• CSCsd52292—The controller does not accept uppercase MAC addresses from the WCS templates.
Workaround: Do not use uppercase characters for MAC addresses in the WCS templates.
• CSCsd52483—When you make changes in the boot loader of a 2006 controller or a Controller
Network Module, the bootup process may halt, and the controller may stop responding.
Workaround: None at this time. The controller must be returned for repair through the RMA process.
• CSCsd65307—When radio resource management (RRM) is enabled on the controller, 1000 series
access points sometimes fail to send an acknowledge packet (or send the packet after a delay) in
response to a reassociation request. As a result, a wired IP phone cannot call an N900iL handset until
the handset resends a reassociation request to the access point.
Workaround: None at this time.
• CSCsd67332—If you have Telnet enabled and then disable it, the change does not take effect until
you reboot the Cisco WiSM.
Workaround: None at this time.
• CSCsd69158—After a RADIUS session timeout expires, the access point does not send a unicast
key to the client.
Workaround: None at this time.
• CSCsd75245—The management packet for the UserIdleTimer is incorrect on access points in REAP
mode.
Workaround: None at this time.
• CSCsd82363—Channel utilization is incorrectly reported in radio utilization reports on the
controller and in WCS. Channel utilization may appear as zero when there is active client traffic or
as an aggregate of client transmit and receive traffic.
Workaround: None at this time.
