Overview
ISO/IEC 10164-5:1993/Amd 1:1995 is an amendment to the OSI systems management specification for the Event Report Management Function. Its primary purpose is to provide implementation conformance statement (ICS) proformas - standardized tables and forms suppliers must complete to declare which management information and capabilities their products implement. The amendment helps profile specifiers (for example, authors of International Standardized Profiles, ISPs) define explicit, interoperable subsets of functionality for event reporting and handling.
Key topics
- Implementation conformance statement proformas: Introduces standardized proformas (MCS, MICS, MOCS, MRCS, PICS) that suppliers complete to document conformance.
- Management roles: Clarifies manager and agent role support requirements and minimum conformance items for each role (e.g., operations on managed objects, notifications related to the event forwarding discriminator managed object).
- Structured tables: Provides mandatory/optional/conditional status columns and support indicators following the format defined in ITU‑T Rec. X.724 / ISO/IEC 10165‑6.
- Managed objects & notifications: Focus on the event forwarding discriminator managed object class and associated notifications (object creation/deletion, attribute change, state change), plus optional event logging.
- Conformance model:
- Static conformance - role-based requirements and transfer syntax (ASN.1 Basic Encoding referenced).
- Dynamic conformance - procedural and semantic behavior for supported features.
- Management conformance statement requirements - MCS proforma must accompany any claimed conformance; proformas in annexes must be technically identical to those specified.
- Compatibility with OSI conformance/testing: References ITU‑T and ISO/IEC conformance testing frameworks (X.291 / ISO/IEC 9646‑2, X.296 / ISO/IEC 9646‑7).
Practical applications
- Ensuring interoperability between network management products by allowing profile specifiers to require explicit subsets of event-reporting capabilities.
- Enabling vendors to declare precise conformance for procurement, certification, and integration (complete MCS and related proformas).
- Supporting test laboratories and integrators in verifying conformance against a consistent set of proformas and conformance criteria.
- Facilitating development of standardized management profiles (ISPs) that rely on consistent event reporting semantics.
Who should use this standard
- Network management product vendors and implementers
- Profile specifiers and standards authors (ISPs)
- Conformance test houses and certification bodies
- System integrators and procurement teams requiring verifiable event-report capabilities
