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.

ISO/FDIS 21111-10:2021(E)

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. It specifies the requirements for devices and

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

with OSI layers from 4 and 3.

ISO 21111-11 specifies the application layer to session layer requirements and conformance test plans.

It specifies the conformance test plans for devices and systems that include functionality related with

OSI layers from 7 to 5.

[2]

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/FDIS 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.
