Network map display method and network map display program

摘要

It is a method of displaying a connection configuration between L2 switches as a tree-type network map in a communication network to which L2 switches are connected. A correspondence table between the MAC address M (H) of the network monitoring terminal H and the set Row {M (H)} of the port information of the L2 switch Sj that has detected the MAC address M (H) based on the management information received by the network monitoring terminal H from the L2 switch. A correspondence table M2 of M1 and the MAC address M (Sj) of the L2 switch Sj and the set of port information Row {M (Sj)} of the L2 switch which has detected the M1 is created as an MvP table (S01), and after normalization Detecting the connection information between the L2 switches from the MvP table (S02), detecting the parent-child relationship of the switch connection based on the connection information, and creating the inter-switch hierarchy table configured by the information on the parent-child relationship (S03). Then, the connection configuration between the L2 switches is displayed as a tree-type network map (S04).
