Information About CDP
CDP Overview
CDP is a device discovery protocol that runs over Layer 2 (the data-link layer) on all Cisco-manufactured
devices (routers, bridges, access servers, controllers, and switches) and allows network management applications
to discover Cisco devices that are neighbors of already known devices. With CDP, network management
applications can learn the device type and the Simple Network Management Protocol (SNMP) agent address
of neighboring devices running lower-layer, transparent protocols. This feature enables applications to send
SNMP queries to neighboring devices.
