OL-11515-01
Cisco Unified IP Phones support several industry-standard and Cisco networking
protocols required for voice communication.
the supported networking protocols on the Cisco Unified IP Phone 7906G and
7911G.
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.

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 information about
DHCP configurations, refer to the
"Cisco TFTP" chapter in the
Cisco Unified CallManager System
Guide.
