Cisco Unified IP Phone 7962G and 7942G Administration Guide for Cisco Unified Communications Manager 7.0

OL-15483-01

Chapter 1      An Overview of the Cisco Unified IP Phone

    What Networking Protocols are Used?

IEEE 802.1X

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. 

The Cisco Unified IP Phone implements the IEEE 
802.1X standard by providing support for the 
EAP-MD5 option for 802.1X authentication.

When 802.1X authentication is enabled on the 
phone, you should disable the PC port and voice 
VLAN. Refer to the 

“Supporting 802.1X 

Authentication on Cisco Unified IP Phones” section 
on page 1-15 

for additional information.

Internet Protocol (IP)

IP is a messaging protocol that addresses 
and sends packets across the network.

To communicate using IP, network devices must 
have an assigned IP address, subnet, and gateway. 

IP addresses, subnets, and gateways identifications 
are automatically assigned if you are using the 
Cisco Unified IP Phone with Dynamic Host 
Configuration Protocol (DHCP). If you are not 
using DHCP, you must manually assign these 
properties to each phone locally.

Link Layer Discovery 
Protocol (LLDP)

LLDP is a standardized network discovery 
protocol (similar to CDP) that is supported 
on some Cisco and third-party devices. 

The Cisco Unified IP Phone supports LLDP on the 
PC port.

Link Layer Discovery 
Protocol-Media Endpoint 
Devices (LLDP-MED)

LLDP-MED is an extension of the LLDP 
standard developed for voice products.

The Cisco Unified IP Phone supports LLDP-MED 
on the SW port to communicate information such as:

  •

Voice VLAN configuration

  •

Device discovery

  •

Power management

  •

Inventory management

For more information about LLDP-MED support, 
see the 

LLDP-MED and Cisco Discovery Protocol

 

white paper:

http://www.cisco.com/en/US/tech/tk652/tk701/tech
nologies_white_paper0900aecd804cd46d.shtml

Cisco Peer-to-Peer 
Distribution Protocol 
(CPPDP) 

CPPDP is a Cisco proprietary protocol 
used to form a peer to peer hierarchy of 
devices. CPPDP is also used to copy 
firmware or other files from peer devices 
to neighboring devices.

CPPDP is used by the Peer Firmware Sharing 
feature.

Real-Time Transport 
Protocol (RTP)

RTP is a standard protocol for transporting 
real-time data, such as interactive voice 
and video, over data networks.

Cisco Unified IP Phones use the RTP protocol to 
send and receive real-time voice traffic from other 
phones and gateways.
