ISO 21111-11:2021(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] [4]
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
[2]
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.
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, 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.

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 plan 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, for example, "CTC_SOMEIP_ETS_07 – EchoBitfields" is used to organize the CTC
name, where the following is included:
— "CTC" which indicates that this is a conformance test case;
— name/subject of CTC;
— supplemental name, for example, ETS, which is enhanced test system;
— 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 9646-1:1994 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 an 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.

ISO 21111-11:2021(E)
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.

Item Content
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 can 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 docu-
ment itself.
EXAMPLE AUTOSAR SOME/IP Example of a Serialization Protocol V1.1.0 R4.1 rev 3: PRS_
SOMEIP_00042, PRS_SOMEIP_00099, …
Prerequisite The purpose of prerequisites is to specify the test hardware and/or software needed to per-
form 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
procedure below.
EXAMPLE The test system set-up shall be in accordance with Figure 2.
Step The test procedure includes the test description, which contains the systematic instructions
for carrying out the test. It provides a cookbook approach to testing and may be interspersed
with observable results. Each test step shall have a numeric number in ascending order.
1. Configure the IUT as master or as slave.
2. Establish a valid link with the IUT.
3. Monitor the transmissions from the IUT and cause the management to request a PMA
reset while simultaneously ceasing transmissions from the test system.
Iteration The purpose of test iterations is to include test procedure definitions, which are repeated more
than once.
a) REPEAT step 2 to step 3 with the IUT configured as master, 1 time.
b) REPEAT step 2 to step 3 with the IUT configured as slave, 1 time.
Expected The purpose of expected response is to describe the expected results to be examined by the
response test system Host-1 in order to verify that the IUT is operating. When multiple values for an
observable are possible, this description provides a short discussion on how to interpret them.
The determination of a pass or fail outcome for a particular test is generally based on the suc-
cessful (or unsuccessful) detection of a specific observable.
After iteration a): The IUT stops transmitting with tx_mode = SEND_N and starts trans-
mitting with tx_mode = SEND_I for 1 iteration a). The IUT sets link_status = FAIL.
After iteration b): The IUT stops transmitting for 1 iteration b). The IUT sets link_status
= FAIL.
Remark The purpose of remarks is to describe known issues with the test procedure, which can affect
test results in certain situations. It can also refer the reader to test suite annexes and/or white
papers that can provide more detail regarding these issues.

ISO/FDIS 21111-11:2021(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] [4]
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
[2]
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.
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, 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/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.

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 plan 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, for example, "CTC_SOMEIP_ETS_07 – EchoBitfields" is used to organize the CTC
name, where the following is included:
— "CTC" which indicates that this is a conformance test case;
— name/subject of CTC;
— supplemental name, for example, ETS, which is enhanced test system;
— 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 9646-1:1994 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 an 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 can 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 docu-
ment itself.
EXAMPLE AUTOSAR SOME/IP Example of a Serialization Protocol V1.1.0 R4.1 rev 3: PRS_
SOMEIP_00042, PRS_SOMEIP_00099, …
Prerequisite The purpose of prerequisites is to specify the test hardware and/or software needed to per-
form 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
procedure below.
EXAMPLE The test system set-up shall be in accordance with Figure 2.
Step The test procedure includes the test description, which contains the systematic instructions
for carrying out the test. It provides a cookbook approach to testing and may be interspersed
with observable results. Each test step shall have a numeric number in ascending order.
1. Configure the IUT as master or as slave.
2. Establish a valid link with the IUT.
3. Monitor the transmissions from the IUT and cause the management to request a PMA
reset while simultaneously ceasing transmissions from the test system.
Iteration The purpose of test iterations is to include test procedure definitions, which are repeated more
than once.
a) REPEAT step 2 to step 3 with the IUT configured as master, 1 time.
b) REPEAT step 2 to step 3 with the IUT configured as slave, 1 time.
Expected The purpose of expected response is to describe the expected results to be examined by the
response test system Host-1 in order to verify that the IUT is operating. When multiple values for an
observable are possible, this description provides a short discussion on how to interpret them.
The determination of a pass or fail outcome for a particular test is generally based on the suc-
cessful (or unsuccessful) detection of a specific observable.
After iteration a): The IUT stops transmitting with tx_mode = SEND_N and starts transmitting
with tx_mode = SEND_I for 1 iteration a). The IUT sets link_status = FAIL.
After iteration b): The IUT stops transmitting for 1 iteration b). The IUT sets link_status =
FAIL.
Remark The purpose of remarks is to describe known issues with the test procedure, which can affect
test results in certain situations. It can also refer the reader to test suite annexes and/or white
papers that can provide more detail regarding these issues.
