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.
