Caveats
Non-Cisco Aironet Clients Sometimes Fail 802.1x Authentication
Some non-Cisco Aironet client adapters do not perform 802.1x authentication to the access point unless
you configure Open authentication with EAP. To allow both Cisco Aironet clients using LEAP and
non-Cisco Aironet clients using LEAP to associate using the same SSID, you might need to configure
the SSID for both Network EAP authentication and Open authentication with EAP.

Microsoft Patch Fixes WPA Authentication Delay
When the access point is configured for optional or mandatory WPA authentication, client adapters in
Windows XP platforms sometimes experience a delay when initially authenticating to the access point
immediately after it starts up. A patch from Microsoft resolves this issue. The patch is described in
Microsoft Knowledge Base Article 826942.

Open Caveats
These caveats are open in Cisco IOS Release 12.2(15)XR:
•
CSCeb50727—Unpowered 1100 series access points sometimes cause a loopback when connected
to switches without loopback detection. When you connect an unpowered 1100 series access point
to some switches without loopback detection, the access point sometimes causes a loopback. To
avoid this problem, make sure loopback detection is enabled on the switch to which the access point
is connected. If your switch does not have loopback detection, disconnect the access point from the
switch when the access point power is off.

CSCeb52431—When logging into a TACACS+ server, 1100 series access points sometimes send
hundreds of additional authentication requests to the server after a successful authentication.

CSCec73044—When WPA is configured on the access point, associated client devices occasionally
report MIC failures on packets from the access point.

•
CSCed42897—The access point sends a get tlv command when the MAC is enabled. However, the
access point should send the get tlv command only when the MAC is disabled.

CSCed63953—The access point information element always transmits the default QoS CWMin
value for best effort regardless of the value that you enter for that setting.

CSCed67615—When you configure filtering on the GUI, MAC address filtering sometimes fails
when you allow all addresses except a range of specific MAC addresses.
when you allow all addresses except a range of specific MAC addresses.
Workaround: Use the CLI to configure multicast MAC address filtering on the bridge groups.

CSCed75292—The access point radio sometimes reboots when a client device attempts to
authenticate at the same time that you enter this command on the access point CLI:
authenticate at the same time that you enter this command on the access point CLI:
show aaa user all
Workaround: Disable the access point radio before you enter the show aaa user all command.
