Workaround: Configure WME policy to be allowed for the wireless LAN on the wireless LAN
controller. To do this on the GUI, browse to the WLANs > Edit page for the appropriate WPAv1
wireless LAN, and in the drop-down menu next to WME policy, select Allowed or Required.
The allowed option means that both WME and non-WME clients can authenticate and receive an
IP address; for example, both Aironet ACU 6.4/6.5 and 6.3 clients could authenticate and receive an
IP address. The required option means that only WME clients can authenticate; that is, only ACU
6.4/6.5 clients.

CSCsb54444—RLDP does not work for regulatory domain -E. This condition applies only to
countries which require DFS (radar detection) support.

Workaround: Do not enable RLDP in these countries.

CSCsb55937—VLAN-tagged large ICMP packets that need to be fragmented are not sent by Cisco
Aironet 1000 series lightweight access points in direct-connection mode. Ping replies never come
back when the Cisco Aironet 1000 series lightweight access point is sending requests to a gateway
from a wireless client using large 1500-byte packets, and with RADIUS override configured with
any 1p tag. This condition exists for Cisco 4400 Series Wireless LAN Controllers using
direct-connect mode, with RADIUS override enabled, the override parameter set to 1p with any
VLAN number, and Cisco Aironet 1000 series lightweight access points.

CSCsb57305—Some Cisco Aironet lightweight access points transmit beacons after the associated
wireless LAN is deleted from the wireless LAN controller. This happens only for wireless LANs
with radio policy set to 802.11g only and when 802.11g support is globally disabled.

Workaround: If you have a wireless LAN with radio policy 802.11g only, do not disable 802.11g
support.

CSCsb63479—Clicking the Refresh link on the Cisco APs page sometimes results in a Page Not
Found error. This generally occurs when there are more than 80 Cisco Aironet lightweight access
points connected to the wireless LAN controller.

CSCsb65096—After changing the bridging shared secret key, the shared secret keys may not be
uniformly distributed across the bridge or mesh network. This can cause some Cisco Aironet
lightweight access points to fail to connect to the wireless LAN controller using LWAPP, and the
Cisco Aironet lightweight access points to time out their connections.

Workaround: Upgrade to the latest code. Ensure that the wireless LAN controller is configured as
follows: config network allow-old-bridge-aps disable.
