LLDP

The Cisco Discovery Protocol (CDP) is a device discovery protocol that runs over Layer 2 (the data link

layer) on all Cisco-manufactured devices (routers, bridges, access servers, and switches). CDP allows

network management applications to automatically discover and learn about other Cisco devices

connected to the network.
