Network Protocols
Cisco Unified IP Phones support several industry-standard and Cisco network protocols required for voice
communication. The following table provides an overview of the network protocols that the Cisco Unified
IP Phones support.
Table 1: Supported Network Protocols on the Cisco Unified IP Phones
Usage NotesPurposeNetwork Protocol
If you use BootP to assign IP addresses
to the Cisco Unified IP Phones, the
BOOTP Server option shows “Yes” in the
network configuration settings on the
phone.
BootP enables a network device such
as the Cisco Unified IP Phones to
discover certain startup information,
such as its IP address.
Bootstrap Protocol
(BootP)
The Cisco Unified IP Phones use CDP to
communicate information such as
auxiliary VLAN ID, per port power
management details, and Quality of
Service (QoS) configuration information
with the Cisco Catalyst switch.
CDP is a device-discovery protocol that
runs on all Cisco-manufactured
equipment.
Using CDP, a device advertises its
existence to other devices and receives
information about other devices in the
network.
Cisco Discovery
Protocol (CDP)
CPPDP is used by the Peer Firmware
Sharing feature.
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.
