WLAN Setup Menu
Security Mode The type of authentication that the phone uses to access
the WLAN. Valid values:
• Open—Access to all access points (APs) without
encryption.
• Open with WEP—Open 802.11 authentication but
uses Wired Equivalent Privacy (WEP) for encrypting
the data. Specifies access to all APs and
authentication through WEP keys at the local AP.
• Shared Key—Shared key authentication using WEP.
• LEAP—Lightweight Extensible Authentication
Protocol authentication exchanges a username and
cryptographically secure password with a RADIUS
server in the network (Cisco proprietary version of
EAP). LEAP supports WPA and WPA2.
• EAP-FAST—Extensible Authentication Protocol
Flexible Authentication via Secure Tunneling
exchanges a username and cryptographically secure
password with a RADIUS server in the network
where a PAC (Protected Access Credential) is used to
established a secure tunnel for authentication.
EAP-FAST supports WPA and WPA2.
• AKM—Selects the 802.11 authentication mechanism
automatically from the configuration information
exhibited by the access point. WPA-PSK or WPA
versions 1 or 2 can be used when configured for this
mode.
Note Consider the following when you select AKM: 1)
AKM uses LEAP for 802.1x when using WPA,
WPA2 or CCKM, 2) AKM selects the encryption
method by giving precedence to the strongest key
management type and then the strongest cipher,
and 3) CCKM is not supported with WPA2.
