Important Notes
WPA version 1 option has been removed from the authentication key-management wpa cli and
configuring TKIP only under this interface is not supported. It will be changed to aes-ccm tkip to work
on mixed mode with the following message on the ap console:

Warning: TKIP encryption no longer permitted by itself - AES-CCM has been enabled
Cisco CKM Supports SpectraLink Phones
Cisco CKM (CCKM) key management is designed to support voice clients that require minimal roaming
times. Voice clients must support Cisco Compatible Extensions to benefit from this feature, for the voice
client security mode you selected, please refer to the following URL for the list of CCX versions and
supported clients:

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.

Pings and Link Tests Sometimes Fail to Clients with Both Wired and Wireless
Network Connections
Network Connections
When you ping or run a link test from an access point to a client device installed in a PC running
Microsoft Windows, the ping or link test sometimes fails when the client has both wired and wireless
connections to the LAN. Microsoft does not recommend this configuration. For more information, refer
to Microsoft Knowledge Base article 157025 at this URL:

Layer 3 Mobility Not Supported on Repeaters and Workgroup Bridges
Repeater access points and workgroup bridges cannot associate to an SSID that is configured for Layer
3 mobility. Layer 3 mobility is not supported on repeaters and workgroup bridges.

Hardware Limitation in Cisco Aironet 1250 and 1140 Series Access Points
The beacons on the Cisco Aironet 1250 and 1140 access points can only have output at intervals that are
multiples of 17 milliseconds. When these access points are configured for a 100-millisecond beacon
interval, they transmit beacons every 102 milliseconds. Similarly, when the beacon interval is configured
for 20 milliseconds, these access points transmit beacons every 17 milliseconds.

Potential RFC 3748 Violation
When the following command is configured under the SSID settings (for LEAP authentication):
authentication client username <WORD> password [0 | 7] <LINE>
