Abstract

A method and apparatus are disclosed for operating a network switch without the use of a CPU. A control interface is used to connect the network switch to the external CPU. The control interface generates an initialization signal indicative of the absence of a CPU. Upon receiving the initialization signal, an internal rules checker initializes the network switch. The internal rules checker will then begin receiving data frames and forwarding them to the appropriate network stations based on a source address and destination address contained in the data frames.
