Purpose
BootP enables a network device such
as the Cisco Unified IP Phone to
discover certain startup information,
such as its IP address.
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.
DHCP dynamically allocates and
assigns an IP address to network
devices.
DHCP enables you to connect an IP
phone into the network and have the
phone become operational without
you needing to manually assign an IP
address or to configure additional
network parameters.
HTTP is the standard way of
transferring information and moving
documents across the Internet and the
web.

Usage Notes
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.
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.
DHCP is enabled by default. If
disabled, you must manually
configure the IP address, subnet
mask, gateway, and a TFTP server on
each phone locally.
Cisco recommends that you use
DHCP custom option 150. With this
method, you configure the TFTP
server IP address as the option value.
For additional supported DCHP
configurations, refer to Cisco Unified
Communications Manager System
Guide.
Cisco Unified IP Phones use HTTP
for the XML services and for
troubleshooting purposes.
