General

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 Interconnection (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 Information 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.

Introduction

AOM2 12 is applicable in an environment in which end systems are able to take a manager role, an agent role or both. A system acting in the role of a manager is capable of receiving notifications which are generated by managed objects in the system actíng 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 AOM2 12. Any system that claims to support one or more managed object, and therefore to om to a managed object definition, must provide ali the capability function services required to perform the operations defined for the managed object and to convey the notifications it generates. Since al1 managed object inherit the object class and name binding attributes from top, GET operations on these attributes must be supported. AOM2 12 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 illwates 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).
