| CDP was designed and implemented as a simple, low-overhead protocol. Though a CDP frame can be small, it can retrieve a great deal of useful information about connected neighboring Cisco devices. This information can be used to create a network map of the connected devices. Devices connected to neighboring devices can be discovered by using Telnet to connect to the neighbors, and using the show cdp neighbors command to discover what devices are connected to those neighbors.
