Important Notes
Corrupt EAP Packet Sometimes Causes Error Message
During client authentication, the access point sometimes receives a corrupt EAP packet and displays this
error message:
error message:
Oct 1 09:00:51.642 R: %SYS-2-GETBUF: Bad getbuffer, bytes= 28165
-Process= "Dot11 Dot1x process", ipl= 0, pid= 32

You can ignore these messages.
When Cipher is TKIP Only, Key Management Must Be Enabled
When you configure TKIP-only cipher encryption (not TKIP + WEP 128 or TKIP + WEP 40) on any
radio interface or VLAN, every SSID on that radio or VLAN must be set to use WPA or CCKM key
management. If you configure TKIP on a radio or VLAN but you do not configure key management on
the SSIDs, client authentication fails on the SSIDs.

Cisco CKM Supports Spectralink Phones
Cisco CKM (CCKM) key management is designed to support voice clients that require minimal roaming
times. To date, CCKM supports only Spectralink Wireless Phones. Other voice clients have not been
tested with CCKM and are not supported.

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.

Linksys Driver Fixes Bug CSCed60301
When you enable shared key authentication and TKIP on an SSID on a 1200 series access point, some
Linksys client devices cannot associate using the SSID. However, a Linksys driver update fixes the
problem.
