ISO/IEC/IEEE 8802-3:2026/Cor 1:2026

Overview

ISO/IEC/IEEE 8802-3:2026/Cor 1:2026 is an internationally recognized technical corrigendum to the Ethernet standard for telecommunications and Information Technology systems. Jointly maintained by ISO, IEC, and IEEE, this document refines and corrects the requirements for local and metropolitan area networks outlined in ISO/IEC/IEEE 8802-3:2026, aligning with best practices for Ethernet technology. The corrigendum specifically addresses the Ethernet Layer Management attributes in the Link Layer Discovery Protocol (LLDP), adjustments in Energy-Efficient Ethernet (EEE) capabilities, and improvements in the clarity and accuracy of managed object classes for better interoperability and performance in modern network environments.

Key Topics

• Ethernet Layer Management Updates:
  • Introduction and clarification of Boolean-managed attributes for LLDP remote system groups related to Fast Wake functionality and preemption capabilities.
  • Detailed mappings of LLDP managed objects with corresponding variables such as RemTxSystemFW, RemRxSystemFW, and support for preemption status indication.
• Energy-Efficient Ethernet (EEE) Enhancements:
  • Refinements to Fast_Wake_Enable attribute exchanges between transmitting and receiving link partners.
  • Improved procedural descriptions for state changes involving link partners as they advertise or respond to changes in energy-saving configurations.
• Preemption Support Indicators:
  • Addition of attributes for indicating support, enablement, and activation of preemption on Ethernet ports, allowing for robust management and higher reliability in time-sensitive networking scenarios.
  • Introduction of minimum non-final fragment size attributes to facilitate accurate and efficient fragment handling in preemptive transmission scenarios.
• Editorial Corrections:
  • Correction of subclause numbering to ensure coherency and ease of implementation for software and device manufacturers.
