ISO 21111-4:2020(E)
Introduction
The ISO 21111 series includes in-vehicle Ethernet requirements and test plans that are disseminated in
other International Standards and complements them with additional test methods and requirements.
The resulting requirement and test plans are structured in different documents following the Open
Systems Interconnection (OSI) reference model and grouping the documents that depend on the
physical media and bit rate used.
In general, the Ethernet requirements are specified in ISO/IEC/IEEE 8802-3. The ISO 21111 series
provides supplemental specifications (e.g. wake-up, I/O functionality), which are required for in-vehicle
Ethernet applications. In road vehicles, Ethernet networks are used for different purposes requiring
different bit-rates. Currently, the ISO 21111 series specifies the 1-Gbit/s optical and 100-Mbit/s
electrical physical layer.
The ISO 21111 series contains requirement specifications and test methods related to the in-vehicle
Ethernet. This includes requirement specifications for physical layer entity (e.g. connectors, physical
layer implementations) providers, device (e.g. electronic control units, gateway units) suppliers, and
system (e.g. network systems) designers. Additionally, there are test methods specified for conformance
testing and for interoperability testing.
Safety (electrical safety, protection, fire, etc.) and electromagnetic compatibility (EMC) requirements
are out of the scope of the ISO 21111 series.
The structure of the specifications given in the ISO 21111 series complies with the Open Systems
[13] [14]
Interconnection (OSI) reference model specified in ISO/IEC 7498-1 and ISO/IEC 10731 .
ISO 21111-1 defines the terms which are used in this series of standards and provides an overview of
the standards for in-vehicle Ethernet including the complementary relations to ISO/IEC/IEEE 8802-3,
the document structure, type of physical entities, in-vehicle Ethernet specific functionalities and so on.
ISO 21111-2 specifies the interface between reconciliation sublayer and physical entity including
reduced gigabit media independent interface (RGMII), and the common physical entity wake-up and
synchronized link sleep functionalities, independent from physical media and bit rate.
ISO 21111-3 specifies supplemental requirements to a physical layer capable of transmitting
1-Gbit/s over plastic optical fibre compliant with ISO/IEC/IEEE 8802-3, with specific application to
communications inside road vehicles, and a test plan for physical entity conformance testing.
This document specifies the optical components requirements and test methods for 1-Gbit/s optical in-
vehicle Ethernet.
ISO 21111-5 specifies, for 1-Gbit/s optical in-vehicle Ethernet, requirements on the physical layer at
system level, requirements on the interoperability test set-ups, the interoperability test plan that checks
the requirements for the physical layer at system level, requirements on the device-level physical layer
conformance test set-ups, and device-level physical layer conformance test plan that checks a set of
requirements for the OSI physical layer that are relevant for device vendors.
ISO 21111-6 specifies advanced features of an ISO/IEC/IEEE 8802-3 in-vehicle Ethernet physical layer
(often also called transceiver), e.g. for diagnostic purposes for in-vehicle Ethernet physical layers. It
specifies advanced physical layer features, wake-up and sleep features, physical layer test suite,
physical layer control requirements and conformance test plan, physical sublayers test suite and
physical sublayers requirements and conformance test plan.
ISO 21111-7 specifies the implementation for ISO/IEC/IEEE 8802-3:2017/Amd 1:2017, which defines
the interface implementation for automotive applications together with requirements on components
used to realize this Bus Interface Network (BIN). ISO 21111-7 also defines further testing and system
requirements for systems implemented according to the system specification. In addition, ISO 21111-7
defines the channels for tests of transceivers with a test wiring harness that simulates various electrical
communication channels.

ISO 21111-8 specifies the transmission media, the channel performance and the tests for
ISO/IEC/IEEE 8802-3 in-vehicle Ethernet.
ISO 21111-9 specifies the data link layer requirements and conformance test plan. It specifies the
requirements and test plan for devices and systems with bridge functionality.
ISO 21111-10 specifies the application to network layer requirements and test plan. It specifies the
requirements and test plan for devices and systems that include functionality related with OSI layers
from 3 to 7.

Introduction
The ISO 21111 series includes in-vehicle Ethernet requirements and test plans that are disseminated in
other International Standards and complements them with additional test methods and requirements.
The resulting requirement and test plans are structured in different documents following the Open
Systems Interconnection (OSI) reference model and grouping the documents that depend on the
physical media and bit rate used.
In general, the Ethernet requirements are specified in ISO/IEC/IEEE 8802-3. The ISO 21111 series
provides supplemental specifications (e.g. wake-up, I/O functionality), which are required for in-vehicle
Ethernet applications. In road vehicles, Ethernet networks are used for different purposes requiring
different bit-rates. Currently, the ISO 21111 series specifies the 1-Gbit/s optical and 100-Mbit/s
electrical physical layer.
The ISO 21111 series contains requirement specifications and test methods related to the in-vehicle
Ethernet. This includes requirement specifications for physical layer entity (e.g. connectors, physical
layer implementations) providers, device (e.g. electronic control units, gateway units) suppliers, and
system (e.g. network systems) designers. Additionally, there are test methods specified for conformance
testing and for interoperability testing.
Safety (electrical safety, protection, fire, etc.) and electromagnetic compatibility (EMC) requirements
are out of the scope of the ISO 21111 series.
The structure of the specifications given in the ISO 21111 series complies with the Open Systems
[13] [14]
Interconnection (OSI) reference model specified in ISO/IEC 7498-1 and ISO/IEC 10731 .
ISO 21111-1 defines the terms which are used in this series of standards and provides an overview of
the standards for in-vehicle Ethernet including the complementary relations to ISO/IEC/IEEE 8802-3,
the document structure, type of physical entities, in-vehicle Ethernet specific functionalities and so on.
ISO 21111-2 specifies the interface between reconciliation sublayer and physical entity including
reduced gigabit media independent interface (RGMII), and the common physical entity wake-up and
synchronized link sleep functionalities, independent from physical media and bit rate.
ISO 21111-3 specifies supplemental requirements to a physical layer capable of transmitting
1-Gbit/s over plastic optical fibre compliant with ISO/IEC/IEEE 8802-3, with specific application to
communications inside road vehicles, and a test plan for physical entity conformance testing.
This document specifies the optical components requirements and test methods for 1-Gbit/s optical in-
vehicle Ethernet.
ISO 21111-5 specifies, for 1-Gbit/s optical in-vehicle Ethernet, requirements on the physical layer at
system level, requirements on the interoperability test set-ups, the interoperability test plan that checks
the requirements for the physical layer at system level, requirements on the device-level physical layer
conformance test set-ups, and device-level physical layer conformance test plan that checks a set of
requirements for the OSI physical layer that are relevant for device vendors.
ISO 21111-6 specifies advanced features of an ISO/IEC/IEEE 8802-3 in-vehicle Ethernet physical layer
(often also called transceiver), e.g. for diagnostic purposes for in-vehicle Ethernet physical layers. It
specifies advanced physical layer features, wake-up and sleep features, physical layer test suite,
physical layer control requirements and conformance test plan, physical sublayers test suite and
physical sublayers requirements and conformance test plan.
ISO 21111-7 specifies the implementation for ISO/IEC/IEEE 8802-3:2017/Amd 1:2017, which defines
the interface implementation for automotive applications together with requirements on components
used to realize this Bus Interface Network (BIN). ISO 21111-7 also defines further testing and system
requirements for systems implemented according to the system specification. In addition, ISO 21111-7
defines the channels for tests of transceivers with a test wiring harness that simulates various electrical
communication channels.

ISO 21111-8 specifies the transmission media, the channel performance and the tests for
ISO/IEC/IEEE 8802-3 in-vehicle Ethernet.
ISO 21111-9 specifies the data link layer requirements and conformance test plan. It specifies the
requirements and test plan for devices and systems with bridge functionality.
ISO 21111-10 specifies the application to network layer requirements and test plan. It specifies the
requirements and test plan for devices and systems that include functionality related with OSI layers
from 3 to 7.
