CDP (Cisco Discovery Protocol) allows IP phones to receive and/or transmit

device-related information from/to directly connected devices on the network that are

also using the protocol, and store the information about other devices.

When CDP feature is enabled on IP phones, the IP phones periodically advertise their

own information to the directly connected CDP-enabled switch. The IP phones can also

receive CDP packets from the connected switch. When the VLAN configurations on the IP

phones are different from the ones sent by the switch, the IP phones perform an update

and reboot. This allows the IP phones to be plugged into any switch, obtain their VLAN

IDs, and then start communications with the call control.
