MIB integrative management method for an ATM server

1. Field of the Invention An management information base integrative management method for an asynchronous transfer mode server is disclosed which reduces the load to be applied to CPU processing of an ATM switch body and minimize the influence upon the processing capacity of the other functions then the SNMP function. Upon accessing, from a network management system (NMS) through an ATM switch in which a plurality of servers are incorporated, a management information base of any of the servers in accordance with an SNMP procedure, one of the servers is set as a master server and the others are set as slave servers. Then, from the ATM switch, the master server is accessed representatively in accordance with the SNMP procedure, and from the master server, any of the slave servers is accessed over a virtual connection (VC). A PVC is used for the communication between the ATM switch and the master server, and an SVC is used for the communication between the master server and any of the slave servers.
