Abstract
A network interface device includes a host port, two network ports, and a switch that can direct communications between the host port, and the two network ports. A data processing system includes an information handling system coupled to a first network, and second and third information handling systems. The information handling systems are coupled in series. Communications received by the network that are addressed to the first information handling system are sent to the first information handling system, but not to the second or third information handling system. A method includes directing a communication from an information handling system to a first port when the communication has a target address that is less than the address of the information handling system or to a second port when the communication has a target address that is greater than the address of the information handling system.
