Chapter 1 An Overview of the Cisco Unified IP Phone
Understanding Security Features for Cisco Unified IP Phones
Required Network Components
Support for 802.1X authentication on Cisco Unified IP Phones requires several components, including:
• Cisco Unified IP Phone—The phone acts as the 802.1X supplicant, which initiates the request to
access the network.
• Cisco Secure Access Control Server (ACS) (or other third-party authentication server)—The
authentication server and the phone must both be configured with a shared secret that is used to
authenticate the phone.
• Cisco Catalyst Switch (or other third-party switch)—The switch must support 802.1X, so it can act
as the authenticator and pass the messages between the phone and the authentication server. When
the exchange is completed, the switch then grants or denies the phone access to the network.
