Table 1-1
Supported Networking Protocols on the Cisco Unified IP Phone
Networking Protocol
Purpose
Usage Notes
Bootstrap Protocol
(BootP)
BootP enables a network device such
as the Cisco Unified IP Phone to
discover certain startup information,
such as its IP address.
If you are using BootP to assign IP
addresses to the
Cisco Unified IP Phone, the BOOTP
Server option shows “Yes” in the
network configuration settings on the
phone.
Cisco Discovery
Protocol (CDP)
CDP is a device-discovery protocol
that runs on all Cisco-manufactured
equipment.
Using CDP, a device can advertise its
existence to other devices and receive
information about other devices in
the network.
The Cisco Unified IP Phone uses
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.
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.
