CDP
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
