Chapter 11 Configuring Authentication Types
 Matching Access Point and Client Device Authentication Types
Applying an EAP Profile to an Uplink SSID
This operation typically applies to repeater access points. Beginning in the privileged exec mode, follow 
these steps to apply an EAP profile to the uplink SSID.
Matching Access Point and Client Device Authentication Types 
To use the authentication types described in this section, the access point authentication settings must 
match the authentication settings on the client adapters that associate to the access point. Refer to the 
Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Windows for 
instructions on setting authentication types on wireless client adapters. Refer to Chapter 10, 
“Configuring Cipher Suites and WEP,” for instructions on configuring cipher suites and WEP on the 
access point. 
Table 11-2 lists the client and access point settings required for each authentication type.
Note 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.
Likewise, to allow both Cisco Aironet 802.11a/b/g client adapters (CB21AG and PI21AG) running 
EAP-FAST and non-Cisco Aironet clients using EAP-FAST or LEAP to associate using the same SSID, 
you might need to configure the SSID for both Network EAP authentication and Open authentication 
with EAP.
