A system for transferring a frame within an Ethernet network of a vehicle. The system includes an Ethernet switch, first and second feature modules and a NAM. The Ethernet switch includes first and second ports connected respectively to the first and second feature modules. The NAM: receives a priority request message from the second feature module; generates a priority response message indicating information for the second feature module to set a priority level of a frame; and transmits the priority response message to the second feature module. The Ethernet switch: receives the frame from the second feature module at the first port, where the frame has a first bit indicative of the priority level and a second bit indicative of a port of the first feature module; and forwards the frame, based on the first and second bits, to a corresponding one of the queues having the priority level and for transmission to the port of the first feature module.
