Overview
ISO/IEC 10164-11:1994/Amd 1:1998 is an amendment to the OSI Systems Management standard dealing with metric objects and attributes. Amendment 1 adds and formalizes Implementation Conformance Statement (ICS) proformas - including Management Conformance Summary (MCS), Management Information Conformance Summary (MICS), Managed Object Conformance Statement (MOCS) and Managed Relationship Conformance Statement (MRCS) proformas - used to declare and verify conformance of implementations. The amendment is published jointly with ITU‑T as X.739/Amd.1.
Key topics and requirements
- Conformance structure: Defines both static and dynamic conformance concepts for manager and agent roles. Implementations must declare which role(s) they support.
- Proforma requirements: MCS, MICS, MOCS and MRCS proformas in Annexes E–N must be used exactly (table numbering and index preserved) when suppliers produce conformance statements.
- Minimum role requirements:
- Manager role: must support at least one management operation or notification for the metric managed objects; specific minimum notifications are listed (object creation, deletion, attribute change, state change, QoS alarm).
- Agent role: must support one or more instances of specified managed object classes (e.g., mean monitor, mean and variance monitor, moving average mean monitor, monitor metric, etc.).
- Encoding / transfer syntax: Requires support for the ASN.1 transfer syntax derived from CCITT Rec. X.209 | ISO/IEC 8825 named {joint‑iso‑itu‑t asn1(1) basicEncoding(1)} for abstract data types referenced.
- Conformance documentation: Suppliers complete the MCS (Annex E) and any referenced ICS proformas per ITU‑T Rec. X.724 | ISO/IEC 10165‑6 instructions.
- Traceability: Amendment cross‑references conformance testing standards such as ISO/IEC 9646 series and related ITU‑T recommendations.
Practical applications and users
Who uses this standard:
- Product vendors and suppliers preparing formal conformance statements for system management products.
- Developers of management agents and managers that implement OSI metric objects and need to demonstrate conformance.
- Conformance testers and QA teams validating implementations against proforma requirements.
- Procurement and interoperability teams requiring standardized declarations of management capabilities.
Typical use cases:
- Producing an MCS/MOCS to accompany a management agent or manager product.
- Verifying which metric monitor object classes an implementation supports (for network monitoring, performance measurement, QoS alarms).
- Ensuring consistent conformance documentation for interoperability testing and certification.
