802.1X authentication
Cisco Unified IP Conference Phone 8831 supports 802.1X Authentication.
Overview
Cisco Unified IP Phones and Cisco Catalyst switches traditionally use Cisco Discovery Protocol (CDP) to
identify each other and determine parameters such as VLAN allocation and inline power requirements.
Cisco Unified IP Phones also contain an 802.1X supplicant. This supplicant allows network administrators
to control the connectivity of IP phones to the LAN switch ports. The current release of the phone 802.1X
supplicant uses EAP-FAST and EAP-TLS options for network authentication.
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 another other third-party authentication server
The authentication server and the phone must both be configured with a shared secret that authenticates
the phone.
