Cisco Discovery Protocol (CDP)
is a proprietary Data Link Layer protocol implemented in Cisco networking equipment.
It's primarily used to obtain IP addresses of neighboring devices and discover their
platform information. CDP is also used to obtain information about the interfaces the
access point uses. CDP runs only over the data link layer enabling two systems that
support different network-layer protocols to learn about each other.
