Port :30718Lantronix Discovery

Lantronix Discovery operates over UDP port 30718 to identify Lantronix serial-to-Ethernet devices on a local network. The discovery protocol typically involves broadcast packets sent from a management application or utility, enabling rapid detection of compatible hardware. When receiving these packets, Lantronix devices respond with identifying information, such as device type, MAC address, IP configuration, and firmware version, simplifying onboarding and inventory management.

These devices primarily serve as serial port servers, bridging legacy serial devices with modern IP networking. Discovery functionality is especially helpful during deployment, firmware updates, or when troubleshooting network issues, as it provides centralized visibility and access without requiring manual IP address configuration.

The protocol is proprietary to Lantronix but resembles other device discovery mechanisms used in IoT environments. It is generally lightweight, designed for ease of integration and minimal overhead within trusted network segments. Since it uses UDP broadcasts, it is predominantly effective only inside the same broadcast domain unless relay agents or special routing configurations are in place.
