Abstract
A system and method for a network within the vehicle that includes a microcontroller unit (MCU) located within the vehicle, which includes an internal ethernet switch and an auxiliary core manager, where the MCU hosts one or more software builds and the auxiliary core manager manages the internal ethernet switch and the software builds. An external ethernet switch located within the vehicle couples one or more ports of the internal ethernet switch to one or more devices through one or more virtual local area networks (VLANs) where upon an occurrence of a reflash event the auxiliary core manager generates a VLAN configuration and filtering rule for the internal switch, associating the software builds to the MCU ports based on a MAC and IP address of each MCU port.
