Full title and description
IEEE Standard for Local and Metropolitan Area Networks — Media Access Control (MAC) Service Definition — Corrigendum 1: Logical Link Control (LLC) Encapsulation EtherType. This corrigendum corrects the published LLC Encapsulation EtherType value in IEEE Std 802.1AC‑2016.
Abstract
This document is a technical corrigendum to IEEE Std 802.1AC‑2016. It corrects the value used for the LLC encapsulation EtherType in the standard’s normative text and tables to ensure consistent interpretation and interoperability of LLC-encapsulated frames across IEEE 802 implementations. The corrigendum is a short, targeted correction rather than a full amendment.
General information
- Status: Active corrigendum to IEEE Std 802.1AC‑2016 (officially published as IEEE 802.1AC‑2016/Cor 1‑2018).
- Publication date: 9 November 2018 (Board approval and publication in 2018).
- Publisher: IEEE Standards Association (IEEE Computer Society / LAN/MAN Standards Committee).
- ICS / categories: Information technology / networking (commonly listed under ICS 35.110 or similar networking categories).
- Edition / version: IEEE Std 802.1AC‑2016/Cor 1‑2018 (Corrigendum 1 to IEEE 802.1AC‑2016).
- Number of pages: Corrigendum documents are short; vendor and catalog listings vary (some list a 1‑page corrigendum entry while others list a longer packaged PDF of ~13 pages including cover/metadata). Users should refer to the official IEEE PDF for the exact file length.
Scope
The corrigendum specifically corrects the LLC Encapsulation EtherType value(s) in IEEE Std 802.1AC‑2016. Its scope is limited to fixing the erroneous EtherType notation so that implementations that rely on the standard’s LLC/EtherType mappings behave consistently. It does not introduce new functionality or protocol mechanisms beyond this correction.
Key topics and requirements
- Correction of the LLC Encapsulation EtherType value used in normative tables and examples in IEEE 802.1AC‑2016.
- Clarification to ensure consistent handling of LLC-encapsulated frames by MAC implementations and bridging functions.
- Administrative update to the base standard (no new protocol behaviors or mandatory feature additions).
- Adoption/alignment with the corresponding ISO/IEC adoption (see related ISO/IEC/IEEE technical corrigendum).
Typical use and users
Primary users are implementers and vendors of IEEE 802 network equipment (NICs, switches, bridges), network‑stack developers, conformance and interoperability test laboratories, and standards librarians. The corrigendum is used when implementing, testing, or validating LLC encapsulation behavior in accordance with IEEE Std 802.1AC. It is also relevant to anyone maintaining documentation or firmware that references the LLC EtherType defined in the 2016 standard.
Related standards
Base and related documents include: - IEEE Std 802.1AC‑2016 (Media Access Control (MAC) Service Definition) — the base standard corrected by this corrigendum. - IEEE Std 802.1AC‑2016/Cor 1‑2018 (this corrigendum). - ISO/IEC/IEEE 8802‑1AC/Cor 1 (adoption of the corrigendum into the ISO/IEC/IEEE joint collection). - Other IEEE 802.1 family standards (for context), e.g., IEEE 802.1Q (bridging/VLANs) and IEEE 802.1AB (LLDP), which interact with MAC/LLC behavior.

FAQ
Q: What is this standard?
A: It is Corrigendum 1 to IEEE Std 802.1AC‑2016, titled "Logical Link Control (LLC) Encapsulation EtherType" — a short technical correction that fixes the LLC Encapsulation EtherType value in the 2016 MAC Service Definition.
Q: What does it cover?
A: It corrects the EtherType value(s) associated with LLC encapsulation in the normative text and tables of IEEE Std 802.1AC‑2016 so implementations parse and generate LLC‑encapsulated frames consistently. It does not add new protocol features.
Q: Who typically uses it?
A: Network equipment vendors, OS/network‑stack developers, interoperability test labs, and standards maintainers who need to ensure their MAC/LLC implementations conform to the corrected mapping.
Q: Is it current or superseded?
A: The corrigendum is an active published correction to IEEE Std 802.1AC‑2016 (published 9 November 2018) and was later adopted into the ISO/IEC/IEEE joint collection (technical corrigendum adopted in 2020). It does not supersede the base standard; it amends it. For the latest consolidated text, consult the IEEE/ISO/IEC combined publication or the IEEE Get Program PDF.
Q: Is it part of a series?
A: Yes — it is part of the IEEE 802.1 family of standards (network architecture, bridging, MAC service definitions). It is Corrigendum 1 for the 2016 release of 802.1AC and complements other 802.1 amendments and corrigenda.
Q: What are the key keywords?
A: LLC encapsulation, EtherType, MAC Service, ISS, 802.1AC, corrigendum, interoperability, IEEE Standards.
