Usage Notes
Purpose
Network Protocol
—
BootP enables a network device, such as
the phone, to discover certain startup
information, such as its IP address.
Bootstrap Protocol (BootP)
The 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.
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.
