Management information model conformance testing is carried out according to the corresponding Implementation Conformance Statement (ICS) proforma.Each kind of information model should have its own ICS proforma.In this paper

SMIv2-based ICS proforma is proposed based on the ITU-T methodology for ICS proforma and the grammar rule of SMIv2.Its provides standard format for interface implementers or suppliers to state their implementation of a management information model and can meet all the requirements of information model conformance testing for SNMP(Simple network management protocol)-based network management interface.An MIB-file-based ICS auto generation method is also presented.The system developed by this method is being used for conformance testing for SNMP interface.
