SNMP-based network management method and system

The invention discloses a simple network management protocol (SNMP)-based network management method and a simple network management protocol (SNMP)-based network management, and solves the problem of compatibility of a management information base (MIB) version and adaptability of management capability. The method comprises the following steps that: an SNMP management station examines an MIB supporting capability of an agency; the agency uploads an MIB file if the MIB supporting capability of the agency is not in a management capability range of the SNMP management station, wherein the MIB file is an MIB development document stored by the agency; and the SNMP management station performs corresponding management operation on the agency by utilizing the MIB file. By the invention, if the MIB version of the agency is upgraded to exceed the management capability range of the management station, the management station can identify and manage the MIB version of the agency by the method, and can provide newly added m
