This part of ISO/IEC ISP 11183 specifies how the OSI Common Management Information Service Element (CMISE) combined with the OSI Remote Operation Service Element (ROSE) shall be used to provide the complete set of operation and notification services to the CMISE-service-users of two end systems. It specifies the CMIP/ROSE protocol features for the definition of the Enhanced Management Communications profile, AOM12. This part of ISO/IEC ISP 11183 can be used together with the part 1 and any connection-mode Transport profile to specify the complete communication requirements for systems management.This part of ISO/IEC ISP 11183 defines the support level of all the OSI management communication features needed by implementations. It specifies general purpose management communication capabilities by requiring the support of all the CMIP functional units except the extended services functional unit. Other profiles may be defined that provide a subset of capabilities specified here.The support of the complete set of operation and notification services, and of the corresponding protocol elements does not imply that all these features shall be used in all instances of communications. The selection of the features depends on the needs and dynamic requirements of the CMISE-service-users who may choose between:application entity roles, functional units, operation/notificationservices, optional parameters.It only implies that a conforming implementationof the CMISE/ROSE services provider does not restrict the capabilities of the CMISE-service-users and complies with the static CMIP requirements specified in ISO/IEC 9596-1 and ISO/IEC 9596-2.NOTES1 The operations and notifications relate to managed objects. The specification and the support of these managed objects are outside the scope of the profile AOM12.2 This part of ISO/IEC ISP 11183 is based on ISO/IEC 9596-2. (SC21 N-7036. 2 June 1992).
