This Recommendation | International Standard defines a Systems Management Function which may be used by an application process in a centralized or decentralized management environment to interact for the purpose of systems management, as defined by CCITT Rec. X.700 | ISO/IEC 7498-4. This CCITT Recommendation | International Standard defines the Log Control function and consists of services and two functional units. This function is positioned in the application layer of the CCITT Rec. X.200 | ISO/IEC 7498-1 and is defined according to the model provided by ISO/IEC 9545. The role of systems management functions is described by CCITT Rec. X.701 | ISO/IEC 10040. This CCITT Recommendation | International Standard — establishes user requirements for the Log Control function; — establishes models that relate the services provided by the function to user requirements; — defines the services provided by the function; — specifies the protocol that is necessary in order to provide the services; — defines the relationship between the services and SMI operations and notifications; — defines relationships with other systems management functions; — specifies conformance requirements. This CCITT Recommendation | International Standard does not — define the nature of any implementation intended to provide the Log Control function; — specify the manner in which management is accomplished by the user of the Log Control function; — define the nature of any interactions which result in the use of the Log Control function; — specify the services necessary for the establishment, normal and abnormal release of a management association; — specify the authorization requirements for the use of the Log Control function or for any associated activity; — define the definitions of managed objects related to the management of particular protocol machines.
