Extensible Authentication Protocol - Flexible Authentication via Secure Tunneling (EAP-FAST)
Extensible Authentication Protocol - Flexible Authentication via Secure Tunneling (EAP-FAST) encrypts EAP transactions
within a Transport Level Security (TLS) tunnel between the access point and the Remote Authentication Dial-in User Service
(RADIUS) server such as the Cisco Access Control Server (ACS) or Cisco Identity Services Engine (ISE).
The TLS tunnel uses Protected Access Credentials (PACs) for authentication between the client (the Cisco Wireless IP Phone
8821 and 8821-EX) and the RADIUS server. The server sends an Authority ID (AID) to the client, which in turn selects the
appropriate PAC. The client returns a PAC-Opaque to the RADIUS server. The server decrypts the PAC with its master-key.
Both endpoints now have the PAC key and a TLS tunnel is created. EAP-FAST supports automatic PAC provisioning, but it
must enable don the RADIUS server.
To enable EAP-FAST, a certificate must be installed on to the RADIUS server.
The Cisco Wireless IP Phone 8821 and 8821-EX currently support automatic provisioning of the PAC only, so enable Allow
anonymous in-band PAC provisioning on the RADIUS server as shown below.
Both EAP-GTC and EAP-MSCHAPv2 must be enabled when Allow anonymous in-band PAC provisioning is enabled.
EAP-FAST requires that a user account be created on the authentication server.
