About CDP
CDP is a protocol that runs over Layer 2 (the data link layer) on all Cisco routers, bridges, access servers,
and switches. CDP allows network management applications to discover Cisco devices that are
neighbors of already known devices, in particular, neighbors running lower-layer, transparent
protocols.With CDP, network management applications can learn the device type and the SNMP agent
address of neighboring devices. CDP enables applications to send SNMP queries to neighboring devices.
CDP runs on all LAN and WAN media that support Subnetwork Access Protocol (SNAP).
