Overview
ISO/IEC 10742:1994 - Information technology - Telecommunications and information exchange between systems - Elements of management information related to OSI Data Link Layer standards - specifies the management information model for the OSI Data Link Layer. It defines the set of managed object classes, their relationships and attributes, and the action-type operations available to systems management for Data Link Layer functions. The standard is focused on information definitions (what to manage) rather than on how management is implemented.
Key topics
- Managed object definitions and hierarchy
- Core objects include the Data Link Subsystem, Data Link Entity, Data Link Service Access Point (DLSAP), LAPB Data Link Entity, MAC and LLC related managed objects (e.g., SLP machines, connections, initial-value objects).
- GDMO and ASN.1 modules
- Uses GDMO templates (Guidelines for the Definition of Managed Objects) and provides an ASN.1 module to represent management information syntactically.
- Attributes, relationships and operations
- Specifies attribute types, relationship attributes and allowed action operations for OSI systems management in accordance with the Structure of Management Information.
- Conformance
- Defines conformance requirements to ISO/IEC 10742 and protocol-specific conformance criteria.
- Normative and informative references
- Annexes
- Includes object identifier allocation, IEEE 802.1 common models, ASN.1 modules, shorthand object descriptions and usage examples.
Applications
- Network equipment vendors and firmware developers implementing OSI-compliant Data Link protocols (LAPB, LLC, MAC) use this standard to expose consistent management information.
- Network management system (NMS) designers and systems integrators use the managed object definitions to model Data Link Layer state, events and configuration within management consoles.
- Standards bodies and implementers referencing GDMO/ASN.1 representations for interoperability testing and conformance validation.
- Telecommunications and enterprise network architects who require a formalized management information model for Data Link Layer monitoring, fault reporting and configuration.
Who should use it
- Telecom and networking engineers, NMS developers, protocol implementers, and compliance/test laboratories working with OSI Data Link Layer management and device interoperability.
