ISO 21111-10:2021(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
[1] [2]
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 21111-2 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.
ISO 21111-4 specifies the optical components requirements and test methods for 1-Gbit/s optical
invehicle 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 8802-3:2021, 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.

This document is based on OSI service conventions as specified in ISO/IEC 10731 .
6 CTP test system set-up and CTC structure
6.1 General
This document specifies a CTP according to the requirements as specified in the ISO/IEC 9646 series.
A CTP does not provide qualification of test results but expected responses of the IUT. A CTP is used by
a test house to develop a conformance test specification specific for the test system used in their lab
environment.
The CTCs specified in this document are organized in such a manner as to simplify the identification
of information related to a test and to facilitate in the actual testing process. CTCs are organized into
groups, primarily in order to reduce set-up time in the lab environment. The different groups typically
also tend to focus on specific aspects of device functionality.
A CTC reference name, e.g. "ARP_03 – ARP entry learned on ARP request (no ARP request)" is used to
organize the CTC name, where:
— CTC indicates that this is a conformance test case;
— name/subject of CTC;
— supplemental name, e.g. ARP, which is address resolution protocol;
— CTC number;
— after the hyphen a descriptive name of the CTC follows.
The CTC definitions themselves are intended to provide a high-level description of the purpose,
references, prerequisite, steps/procedures, expected responses, remarks, and methodologies pertinent
to each test (see 6.3).

ISO 21111-10:2021(E)
6.2 Test system set-up
The test system topology follows ISO/IEC 9646-1 and consists of a test set-up which consists of a test
system and a system under test (SUT) connected via the physical medium. The test system implements
a UT and an LT. The UT uses the test control protocol (Figure 2, key 2) to control the LT. The LT supports
the functionality required to test the OSI layer (Figure 2, key 5, key 6, and key 7) of the IUT. The test
system uses IUT-specific set-up parameters (Figure 2, key 1) for testing the communication with the
IUT.
The control and measurement functionality is provided by direct logical access to the service interface
(dashed line) (Figure 2, key 3) and the associated parameters of the OSI layer. The UT in the IUT
(Figure 2, key 4) supports an equivalent part of the abstract service interface (ASPs, PCO) (dashed line)
(Figure 2, key 3) and the associated parameters to control and measure the state(s) of the IUT.
The UT conformance test controller in the test system manipulates the service primitive interface
parameters in the IUT via the ASPs (ETSs) and PCO of the OSI layers to fulfil the purpose of each CTC.

6.3 CTC definition
CTCs are independent of one another. Each CTC checks the behaviour of the IUT for a particular purpose
of this document. CTCs, which require variations of individual parameters, shall be repeated for each
value of the parameter. Each CTC is specified according to a common CTC structure as shown in Table 1.
Table 1 — CTC structure
Item Content
CTC # – Title CTC_x.y.z-a – CTC structure
Purpose The purpose is a brief statement outlining what the test attempts are to achieve. The test is
written at the functional level. It is recommended to begin the description of purpose with "This
CTC verifies …".
Reference The purpose of reference is to specify source material external to the test suite, including any
other references that might be helpful in understanding the test methodology and/or test results.
External sources are always referenced by number when mentioned in the test description. Any
other references not specified by number are stated with respect to the test suite document itself.

Prerequisite The purpose of prerequisites is to specify the test hardware and/or software needed to perform
the CTC. This is generally expressed in terms of minimum requirements. In some cases, specific
equipment manufacturer/model information may be provided.
EXAMPLE The IUT is running and offering the enhanced testability service.
Set-up The purpose of set-up is to describe the initial configuration of the test environment. Small
changes in the configuration should not be included here and are generally covered in the test

ISO/FDIS 21111-10:2021(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
[1] [2]
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 21111-2 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.
ISO 21111-4 specifies the optical components requirements and test methods for 1-Gbit/s optical
invehicle 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 8802-3:2021, 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.

systems with bridge functionality.
This document specifies the transport layer and network layer requirements and conformance test
plans. It specifies the conformance test plans for devices and systems that include functionality related

6 CTP test system set-up and CTC structure
6.1 General
This document specifies a CTP according to the requirements as specified in the ISO/IEC 9646 series.
A CTP does not provide qualification of test results but expected responses of the IUT. A CTP is used by
a test house to develop a conformance test specification specific for the test system used in their lab
environment.
The CTCs specified in this document are organized in such a manner as to simplify the identification
of information related to a test and to facilitate in the actual testing process. CTCs are organized into
groups, primarily in order to reduce set-up time in the lab environment. The different groups typically
also tend to focus on specific aspects of device functionality.
A CTC reference name, e.g. "ARP_03 – ARP entry learned on ARP request (no ARP request)" is used to
organize the CTC name, where:
— CTC indicates that this is a conformance test case;
— name/subject of CTC;
— supplemental name, e.g. ARP, which is address resolution protocol;
— CTC number;
— after the hyphen a descriptive name of the CTC follows.
The CTC definitions themselves are intended to provide a high-level description of the purpose,
references, prerequisite, steps/procedures, expected responses, remarks, and methodologies pertinent
to each test (see 6.3).

6.2 Test system set-up
The test system topology follows ISO/IEC 9646-1 and consists of a test set-up which consists of a test
system and a system under test (SUT) connected via the physical medium. The test system implements
a UT and an LT. The UT uses the test control protocol (Figure 2, key 2) to control the LT. The LT supports
the functionality required to test the OSI layer (Figure 2, key 5, key 6, and key 7) of the IUT. The test
system uses IUT-specific set-up parameters (Figure 2, key 1) for testing the communication with the
IUT.
The control and measurement functionality is provided by direct logical access to the service interface
(dashed line) (Figure 2, key 3) and the associated parameters of the OSI layer. The UT in the IUT
(Figure 2, key 4) supports an equivalent part of the abstract service interface (ASPs, PCO) (dashed line)
(Figure 2, key 3) and the associated parameters to control and measure the state(s) of the IUT.
The UT conformance test controller in the test system manipulates the service primitive interface
parameters in the IUT via the ASPs (ETSs) and PCO of the OSI layers to fulfil the purpose of each CTC.

6.3 CTC definition
CTCs are independent of one another. Each CTC checks the behaviour of the IUT for a particular purpose
of this document. CTCs, which require variations of individual parameters, shall be repeated for each
value of the parameter. Each CTC is specified according to a common CTC structure as shown in Table 1.

Purpose The purpose is a brief statement outlining what the test attempts are to achieve. The test is
written at the functional level. It is recommended to begin the description of purpose with "This
CTC verifies …".
Reference The purpose of reference is to specify source material external to the test suite, including any
other references that might be helpful in understanding the test methodology and/or test results.
External sources are always referenced by number when mentioned in the test description. Any
other references not specified by number are stated with respect to the test suite document itself.
