Setting the Wireless LAN Security Mode
The Cisco Unified Wireless IP Phone 7921G supports many types of
authentication. Authentication methods might require a specific encryption
method or you can choose between several encryption methods. When
configuring a network profile, you can choose one of these authentication
methods:
• Open—Provides access to all access points without WEP Key
authentication/encryption.
• Open plus WEP—Provides access to all access points and authentication
through the use of one or more WEP Keys at the local access point.
• Shared Key plus WEP—Provides shared key authentication through the use
of WEP Keys at the local access point.
• LEAP— Exchanges a username and cryptographically secure password with
a RADIUS server for authentication in the network. LEAP is a Cisco
proprietary version of EAP.
• EAP-FAST—Exchanges a username and password and with a RADIUS
server for authentication in the network.
• Auto(AKM)—Automatic authenticated key management in which the phone
selects the AP and type of key management scheme, that can include WPA,
WPA2, WPA-Pre-shared key, WPA2-Pre-shared key, or CCKM which uses a
wireless domain server (WDS).
The type of authentication and encryption schemes that you are using with your
WLAN determine how you set up the authentication, security, and encryption
options in the network profiles for the Cisco Unified Wireless IP Phones.
Table 4-3 provides a list of supported authentication and encryption schemes that
you can configure on the Cisco Unified Wireless IP Phone 7921G.
