ISO/IEC/IEEE 8802-3:2026/Cor 1:2026 is an ISO technical corrigendum for the Ethernet standard used in local and metropolitan area networks. It corrects parts of ISO/IEC/IEEE 8802-3:2026 in the LLDP management clauses and in the Energy-Efficient Ethernet (EEE) link state-change procedure. For implementers and network managers, it clarifies how specific Ethernet management attributes are named and exchanged across a link.

What does ISO/IEC/IEEE 8802-3:2026/Cor 1:2026 specify?

ISO/IEC/IEEE 8802-3:2026/Cor 1:2026 specifies corrections to the Ethernet standard rather than a new Ethernet feature set. The corrigendum focuses on management information for LLDP and on how EEE link partners report and echo Fast_Wake_Enable-related values.

Clause or subclause	What it covers
Clause 30, Management	LLDP management objects and attribute definitions
30.12, Layer Management for LLDP	LLDP layer management
30.12.3, LLDP Remote System Group managed object class	Remote-system management data
30.12.3.1, LLDP Remote System Group attributes	Corrected attribute names and numbering
Clause 78, Energy-Efficient Ethernet (EEE)	EEE capabilities and link behavior
78.4, Data Link Layer capabilities	Capability exchange across a link
78.4.3, State change procedure across a link	How link partners signal changes

What are the key requirements of ISO/IEC/IEEE 8802-3:2026/Cor 1:2026?

The corrigendum updates the Ethernet management model so that implementations use the corrected LLDP attributes and the revised EEE state-change wording. In practice, this matters because management systems, firmware, and test tools must agree on the same attribute names and link-partner behavior.

Corrected LLDP Remote System Group attributes

In 30.12.3.1, ISO/IEC/IEEE 8802-3:2026/Cor 1:2026 renumbers several LLDP Remote System Group attributes and defines the corrected attribute names. The added attributes cover transmit and receive Fast Wake information, preemption status, and additional fragment size. This is important for network management software that reads remote port capabilities and must map the right object identifiers to the right values.

Fast_Wake_Enable exchange across a link

In 78.4.3, ISO/IEC/IEEE 8802-3:2026/Cor 1:2026 clarifies how a receiving link partner can request a change of Fast_Wake_Enable through the local receive-facing LLDP attribute, and how that request appears to the other end as a remote-system attribute. It also states how the transmitting partner responds and how the echoed values are copied between local and remote management objects. In practice, both ends of a link need consistent state reporting so that EEE behavior is interpreted the same way on each side.

Advertising versus echoing values

ISO/IEC/IEEE 8802-3:2026/Cor 1:2026 distinguishes between values a partner advertises and values echoed back by the remote system. This applies to both transmit-direction and receive-direction Fast_Wake_Enable information. The distinction matters because tooling and controllers must know whether a value is a local request, a remote view, or an echoed confirmation.

Preemption-related status

The corrected LLDP attributes also include Boolean indicators for whether a remote port supports preemption, whether preemption is enabled, and whether it is active. In practice, this lets management systems determine whether frame preemption is available and in use on the peer port.

Fragment size reporting

ISO/IEC/IEEE 8802-3:2026/Cor 1:2026 includes an integer attribute for the minimum non-final fragment size on the remote port, expressed in 64-octet units. This matters when implementations need to interpret how large fragments may be before a frame can be split.

What terms does ISO/IEC/IEEE 8802-3:2026/Cor 1:2026 define?

• LLDP (Link Layer Discovery Protocol) - The link management protocol used here to exchange remote-system information.
• EEE (Energy-Efficient Ethernet) - The Ethernet capability area that handles low-power link behavior and wake-related signaling.
• Managed object class - The management-model container that exposes link information through named attributes.
• GET attribute - A read-only attribute that is retrieved from the management object class.
• Preemption capability - A port capability that can be supported, enabled, or active on the remote system.
• Fast_Wake_Enable - The state exchanged between link partners to request or advertise fast-wake behavior.
• LPI_FW - The value carried in the LLDP attributes for fast-wake support or request in a given direction.

Who uses ISO/IEC/IEEE 8802-3:2026/Cor 1:2026?

ISO/IEC/IEEE 8802-3:2026/Cor 1:2026 is used by Ethernet equipment vendors, firmware and software developers, network management tool builders, and test laboratories. It is also relevant to operators and buyers who need to verify LLDP and EEE interoperability on local and metropolitan area networks. Quality teams use it to check that management objects, link-state exchange, and attribute naming match the corrected standard text.

What changed in ISO/IEC/IEEE 8802-3:2026/Cor 1:2026 from the previous edition?

ISO/IEC/IEEE 8802-3:2026/Cor 1:2026 is a technical corrigendum to ISO/IEC/IEEE 8802-3:2026, prepared in IEEE form as IEEE Std 802.3-2022/Cor 1-2024. It corrects:

• the LLDP Remote System Group attribute list in 30.12.3.1, including renumbering and added attribute definitions
• the wording in 78.4.3 that describes how Fast_Wake_Enable changes are requested, advertised, and echoed across a link

Standard	Role in this document
ISO/IEC/IEEE 8802-3:2026	The base Ethernet standard that this corrigendum corrects

What does the ISO/IEC/IEEE 8802-3:2026/Cor 1:2026 document contain?

ISO/IEC/IEEE 8802-3:2026/Cor 1:2026 contains corrected subclause text, not a full rewrite of Ethernet. Its content is concentrated in LLDP management objects and in the EEE state-change procedure. The document gives updated attribute names, attribute mappings, read-only status descriptions, and revised explanatory paragraphs showing how values move between local and remote managed objects. For engineers, this is the part to use when aligning software, management systems, or conformance tests with the corrected Ethernet text.
