PROBLEM TO BE SOLVED: To obtain a network overhead function by a network switch which has one or more network ports each including a network interface, a data path interface, and a processor port interface. SOLUTION: A CPU 230 initializes TPI 220 and FPSM 210 and performs a processing for configuration once powered up with a network switch 102. Statistical information is monitored and gathered and functions of various devices of the network switch 102 are managed and controlled in operation. The CPU 230 functions as an additional network port and is coupled with EPSM 210 through an address and data part 218a and a CPU bus 218 including a relative control and state signal 218b. Thus, the CPU 230 has the overhead function, and consequently the bandwidth for data transfer of a data bus increases.
