Cisco Centralized Key Management (Cckm) - Cisco 7925G Deployment Manual

PEAP (MS-CHAPv2) requires that a user account be created on the authentication server.
The authentication server can be validated via importing a certificate into the Cisco Unified Wireless IP Phone 7925G.
See the "Installing Certificates" section for more information.

Cisco Centralized Key Management (CCKM)

When using 802.1x type authentication, it is recommended to implement CCKM to enable fast roaming. 802.1x can introduce
delay during roaming due to its requirement for full re-authentication. CCKM centralizes the key management and reduces the
number of key exchanges. WPA introduces additional transient keys and can lengthen roaming time.
The Cisco Unified Wireless IP Phone 7925G supports CCKM with WPA (TKIP) and 802.1x (WEP) authentication.
CCKM with WPA (AES) or WPA2 (TKIP/AES) are not supported at this time.
