The technical differences between this document and IEC 61375-2-8:2021, and the reasons therefor, are as follows.

---ISO/IEC 9646-1 and ISO/IEC 9646-7 have been replaced by the normatively referenced GB/T 17178.1 and GB/T 17178.7, respectively.

(See 4.1.1) to adapt to my country's technological conditions;

---ISO/IEC 11801 (all parts) has been replaced with the normatively referenced GB/T 18233 (all parts) (see Tables 30 and 69).

To adapt to my country's technological conditions;

---The consistency between PIXIT and PICS has been changed (see 4.1.3.2). Domestic requirements stipulate that PIXIT should be consistent with PICS.

---The reference standards for Ethernet signal waveform testing methods and their judgment have been changed (see 5.4.6), and the normative reference IEEE has been removed.

802.3az, to adapt to the domestic situation;

---Changes have been made to the Ethernet self-crossing and auto-sensing tests, basic communication protocol tests, and SDSINK---secure data sink tests.

The test methods have been supplemented (see 5.4.8, 5.5.2~5.5.5, 10.4.2.2, 10.4.3.2, 10.4.4.2, 10.4.5.2, 10.4.6.2, 10.4.7.2).

10.4.8.2), to adapt to the domestic situation;

---Added testing for switch support of TRDP (see 7.3.2.16, 7.4.18) to adapt to the domestic situation;

---The priority screening requirements in the ingress rate limit have been modified (see 7.4.7.5) to adapt to the domestic situation;

---The requirements for vital sign overflow have been changed (see Table 148) to facilitate testing operations;

---The method for determining the connection vector transmission test has been changed (see 8.3.9.1 and 8.3.9.2) to facilitate testing operations;

---The test equipment for TRDP conformance testing has been changed (see 9.3), as the original test equipment was too small and not conducive to the test.

---The protocol version testing method has been changed (see 9.6.3.4) to suit the domestic situation;

---The timeout and validity test ports have been changed (see 9.6.4.6) to avoid reusing ComId and facilitate test operations;

---The point-to-point testing method has been modified (see 9.6.4.7) and optimized for easier testing operations;

---The verification method for sequential count overflow has been changed (see 10.3.3.2, 10.3.5.2) to suit the domestic situation.

The following editorial changes have been made to this document.

---To harmonize with existing standards, the standard name has been changed to "Rail Transit Electronic Equipment Train Communication Network (TCN) Parts 2-8" Part. Ethernet Consistency Testing;

---The method of describing test cases has been changed to a table format (see Chapter 8);

---Added "Note 1" and "Note 2" to "Test Suite. IP Multicast Forwarding" (see 8.3.7.1).
