This part of ISO/IEC ISP 12060 specifies the Alarm reporting and state management capabilities profile, AOM212, which is applicable to end systems operating in the Open Systems Inter connection (OSI) environment. AOM212 specifies a combination of OSI standards, which collectively provide Alarm reporting and state management capabilities. These capabilities include the ability to report the alarm notifications, the state change notification, and to retrieve and modify the state attributes.
AOM212 also specifies use of a combination of standards that collectively provide the subset of the Common Management Informatio n Service required by this part of ISO/IEC ISP 12060.
The support of the complete set of operation and notification services and of the management attributes does not imply that all these features shall be used in all instances of communications. The selection of the features depends on the requirements of the MIS users.
The definitions and conventions used in this part of ISO/IEC ISP 12060 are specified in ISO/IEC ISP 12059-0, Common definitions for management function profiles.
AOM212 is applicable in an environment in which end systems are able to take a manager role, an agent role or both. A system acti ng in the role of a manager is capable of receiving notifications which are generated by managed objects in the system acting in the role of the agent. A system acting in the role of a manager is capable of requesting the specified set of operations upon state attributes which are in the system acting in the role of the agent.
The specifications of managed objects are outside the scope of AOM212. Any system that claims to support one or more managed objects, and therefore to conform to a managed object definition, must provide all the capability function services required to perform the operations defined for the managed objec t and to convey the notifications it generates. Since all managed objects inherit the object class and name binding attributes from top, GET operations on these attributes must be supported. AOM212 does not support the minimum capability services needed by a system that claims support for managed objects. Managed objects that contain the state attributes as defined in ISO/IEC 10164-2 may be manipulated via the use of services provided by AOM212.
Figure 1 illustrates only one of those configurations, one in which one system is acting in a manager role and a further system is acting in the agent role.
The roles of manager and agent may be determined in advance, for the duration of an association or the duration of a single management interaction. The application context is defined in Systems Management Overview (ISO/IEC 10040).
NOTE - Negotiation of functional units is optional.
AOM212 references the following standards.
(Application Layer): ISO/IEC 10164-1, Object management function; ISO/IEC 10164-2, State management function; ISO/IEC 10164-4, Alarm reporting function; ISO/IEC 10165-2, Definition of management information; ISO/IEC 9595, CMIS; ISO/IEC 9596-1, CMIP; ISO/IEC 9072-1, 2, ROSE; ISO 8649, 8650, ACSE; ISO/IEC ISP 11183-3, CMISE/ROSE for AOM11 - Basic management communications; ISO/IEC ISP 11183-1, Specifications of ACSE, Presentation and Session.
(Presentation Layer): ISO 8822, 8823, Presentation; ISO/IEC 8824, 8825, ASN.1; ISO/IEC ISP 11183-1, Specification of ACSE, Presentation and Session.
(Session Layer): ISO 8326, 8327, Session; ISO 8326/Add.2; ISO 8327/Add.2; ISO/IEC ISP 11183-1, Specification of ACSE, Presentation and Session.
AOM212 includes by reference the subset of the Basic Management Communications profile (AOM11) that is required to support the above services.
NOTE - Refer to the description of AOM11 for further information about the communications support including specification of the protocol stack.
An end system implementing AOM212 can interwork with an end s ystem implementing the same profile in a complementary role. An end system implementing this profile can also interwork with an end system implementing profiles AOM211 (General Management Capabil ities), or AOM213 (Alarm Reporting Capabilities) in a complementary role, at the common level of functionality. A system implementing the Basic Management Communications profile (AOM11) will be compatible with the communications aspects of AOM212. AOM12 is also compatible with communication aspects of AOM212.
1.3 Position within the Taxonomy
AOM212 is identified in ISO/IEC TR 10000-2 as:
AOM - OSI Management;
AOM2 - Management Functions;
AOM21 - Management Capabilities;
AOM212 - Alarm Reporting and State Management Capabilities.
AOM212 may be combined with any T-Profie (identified in ISO/IEC TR 10000-2) specifying the OSI connection-mode transport service.
