Structure of Management Information

Structure of Management Information (SMI) is a adapted subset of ASN.1 which is used in Simple Network Management Protocol (SNMP) to define sets ("modules") of related managed objects in a Management information base.

SMI is divided into three parts: module definitions, object definitions, and notification definitions.

Module definitions are used when describing information modules. An ASN .1 macro, MODULE-IDENTITY, is used to concisely convey the semantics of an information module.

Object definitions are used when describing managed objects. An ASN.1 macro, OBJECT-TYPE, is used to concisely convey the syntax and semantics of a managed object.

Notification definitions are used when describing unsolicited transmissions of management information. An ASN.1 macro, NOTIFICATION-TYPE, is used to concisely convey the syntax and semantics of a notification.
