802.1x Support
The IP phones support the IEEE 802.1x protocol. The 802.1x protocol is a standard for passing
Extensible Authentication Protocol (EAP) over a wired or wireless Local Area Network (LAN).
The 802.1x protocol on the IP phone facilitates media-level access control, and offers the
capability to permit or deny network connectivity, control LAN access, and apply traffic policy,
based on user or endpoint identity. This feature supports both the EAP-MD5 and EAP-TLS
protocols.
If 802.1x on the phone is enabled, the following screen displays during startup of the phone.
If the 802.1x failed to authenticate with the server, the phone continues it's normal startup
process using DHCP. However, the network port on the phone may or may not be disabled,
depending on the switch configuration.
Certificates and Private Key Information
• If the certificates and private key are NOT stored in the phone:
— the phone connects to an open unauthenticated VLAN and the certificates are
downloaded.
or
— the phone connects using EAP-MD5 to a restricted VLAN and the certificates are
downloaded.
• If the certificates and private key ARE stored in the phone, the phone uses them during the
authentication process.
• If the phone uses EAP-TLS for successful authentication, after the phone reboots, it
downloads the latest certificates and private key files to the phone.
• The private key uses AES-128 to encrypt the private key file.
