Configuring Advanced Operational Features
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.
