CDP (Cisco Discovery Protocol) is a link level protocol that allows for discovering the CDP-awared network hardware at either end of a DIRECT connection.
It's only good for direct connection because CDP doesn't get forwarded through switches. It's a simple advertisement protocol which beacons information about the switch or host along with some port information. The CDP information allows ESX Server admins to know which Cisco switch port is connected to any given virtual switch uplink (PNIC).
