This paper describes the essential specificationand design of a CMIP-SNMPv2 application gateway fornetwork management integration and interoperability.Such a intermediate proxy software device allows management of Internet MIB-II objects throughISO/CCITT manager supporting CMIP protocol and CMISmanagement services. All the gateway functionality areexplained using dataflow diagrams. CMIP indication PDUs are transformed into functionallycorresponding SNMPv2 PDUs. Detailed service-mapping andname-mapping aspects consistent with the protocols,Internet MIB-II and the GDMO MIB are fully explored.SNMPv2 to CMIP inverse mapping is also explained indetail, followed by conclusions capturing the salientaspects of this design.
