BootP enables a network device, such as
the phone, to discover certain startup
information, such as its IP address.
CDP is a device-discovery protocol that
runs on all Cisco-manufactured equipment.
A device can use CDP to advertise its
existence to other devices and receive
information about other devices in the
network.
