The designated UDP port for the LISP (Locator/ID Separation Protocol) Data Plane is UDP 4341. LISP is used to separate the identity and location of network devices, allowing for more efficient routing and better scalability in large networks.

In LISP, the Data Plane involves the actual data packets that are transported across the network. UDP 4341 is specifically assigned for the LISP Data Plane communication, establishing a standard for interoperability among networking devices that implement this protocol. By adhering to this standardized port, devices can correctly send and receive LISP data traffic without conflict with other applications or services.

Other ports mentioned, such as UDP 4342, UDP 4789, or UDP 8080, are not related to the LISP Data Plane. UDP 4342 is commonly used for the LISP Control Plane, which deals with the mapping of identifiers to locators, while UDP 4789 is designated for VXLAN (Virtual Extensible LAN). UDP 8080 is typically used for web services and does not pertain to LISP functionality at all. Therefore, the correct identification of UDP 4341 is crucial for networking professionals to ensure proper implementation and operation of the LISP protocol.
