Which protocol allows a Cisco switch to know details about a connected Cisco IP phone?
Transmission Control Protocol
Real-time Transport Protocol
User Datagram Protocol
Cisco Discovery Protocol
Cisco Discovery Protocol (CDP) is a Layer 2 Cisco proprietary protocol used to find a Cisco neighbor device and learn about the type of hardware, software version, and active interfaces. CDP can be used by a L2 or L3 device. In case that a Cisco IP phone is connected to an access port on a Layer 2 device and CDP is enabled, the switch will send CDP messages and discover the phone's information. It is possible to see the Cisco VoIP phone via the _show cdp neighbors command on a Cisco switch.
