Structure of Management Information

Structure of Management Information (SMI) is an 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.
