Abstract

The present invention is a method to use network switch for controlling computer access to network system and includes the following steps: (1) Establish a lock configuration table in a network switch to record the mapping relations between Internet protocol (IP) and network card number (that is media access control (MAC) address). (2) When a computer is connected to one of the ports of the network switch, the network switch checks whether the mapping relation between the computer's IP and network card number exists in the lock configuration table. (3) If the mapping relation between the computer's IP and network card number is not included in the lock configuration table, the network switch does not allow the computer to access and records the computer's IP and network card number in a locked table. (4) The network switch will still refuse the computer to access even after the network switch detects the mapping relation between the computer's IP and network card number have been altered to match one of the records in the lock configuration table.
