The CDP (Cisco Discovery
Protocol) 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.
