Cisco Unified IP Phone 7931G
Networking Protocol
Hypertext Transfer
Protocol (HTTP)
Hypertext Transfer
Protocol Secure (HTTPS)
IEEE 802.1X
Purpose
HTTP is the standard way of
transferring information and moving
documents across the Internet and the
web.
HTTPS is a combination of HTTP and
the SSL/TLS protocol to provide
encryption and secure identification of
servers.
The IEEE 802.1X standard defines a
client-server-based access control and
authentication protocol that restricts
unauthorized clients from connecting
to a LAN through publicly accessible
ports.
Until the client is authenticated, 802.1X
access control allows only Extensible
Authentication Protocol over LAN
(EAPOL) traffic through the port to
which the client is connected. After
authentication is successful, normal
traffic can pass through the port.

Usage notes
Cisco Unified IP Phones use HTTP for
the XML services and for
troubleshooting purposes.
The Cisco Unified IP Phone does not
support the use of IPv6 addresses in the
URL. You cannot use literal IPv6
addresses in the URL or host name
which maps to a IPv6 address.
Web applications with both HTTP and
HTTPS support have two URLs
configured. The Cisco Unified IP Phone
that supports HTTPS choose the HTTPS
URL out of the two URLs.
The Cisco Unified IP Phone implements
the IEEE 802.1X standard by providing
support for these authentication
methods: EAP-FAST, EAP-TLS, and
EAP-MD5.
When 802.1X authentication is enabled
on the phone, you should disable the PC
port and voice VLAN. For additional
information, see 802.1X Authentication,
on page 20 .
