Abstract: The present invention discloses a system for very simple network management (VSNM), comprising an information database to store or collect various data. An AI (artificial intelligent) engine is coupled to the information data base. A knowledge base rule database is used for storing knowledge base rule and is coupled to the information database and the AI engine. A webpage generator is coupled to the knowledge base rule database and the AI engine. A user interface is coupled to the AI engine. A web server is coupled to the user interface and the webpage generator.

Abstract: A method for locating the incoming port of a MAC address is proposed. First, a forwarding table of each switch is retrieved. Then, a list of at least one MAC address owned by each switch is retrieved. Next, a port table of each switch is established. The MAC addresses in the forwarding table are compared with the MAC addresses owned by all switches. If one of the MAC addresses owned by switches matches the MAC address in the forwarding table, the port property of the corresponding port is changed to an interconnecting port. Finally, the target MAC address is compared with the MAC addresses in the forwarding table. If one of the MAC addresses in the forwarding table matches the target MAC address, and the port property of the corresponding port is end port, this port is the incoming port of the target MAC address.
