Information Technology - International Standardized Profiles - OSI Management - Management Functions - Part 4: AOM221 - General Event Report Management
|Publication Date:||1 April 1996|
This part of ISOEC ISP 12060 specifies th General event report management profile, AOM221, which is applicable to end systems operating in the Open Systems Interconnection (0%)e nvironment. AOM221 specifies a combination of OS1 standards which collectively provide General event report management. General event report management provides a means for selecting which notifications (generated by managed objects) are sent by an open system and where they are sent; this process of selection is referred to as discrimination and the criteria for selection are specified in an Event Forwarding Discriminator (EFD) support managed object.
AOM221 also provides a means for initiating, terminating, suspending and resuming the sending of event reports as well as modification of the selection criteria. These capabilities are achieved by a set of operations upon, and a set of notifications generated by, the EFD object.
AOM221 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 sewices and of the management attributes does not imply that ali these features shall be used in all instances of communication. 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.
AOM221 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 requesting the specified set of operations upon an Event Forwarding Discriminator support managed object which is in the system acting in the role of an agent; the notifications that are discriminated upon are also in the system acting in the role of an agent.
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. Note that the system acting in the manager role for the purposes of AOM221 is not necessarily the same system which receives the discriminated notifications.
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
