Hi NXP TechSupport
My Board : S32g274ardb2
According this file "VNPRDBEEUG.pdf(S32G-VNP-RDB2 Ethernet Enablement Guide)" and I follow page 12 to test each port.
(1)The information of linux version is "Auto Linux BSP 30.0 s32g274ardb2 ttyLF0"
(2)PC PING Board and Board PING PC . The attach file is the test result.
(3)Port to Port test(router test). The attach file is the test result.

Can you help me to giver the answer the fail state ?

For all cases where ping works in one direction but not in the opposite, you
are either pinging the board running u-Boot which does not respond to ICMP, or using an
invalid IP configuration or diagnostic tool. The standard ping
utility requires bidirectional communication to report a success. If you
ping successfully in one direction, the both directions are working. Everything
else is a result of either filtering, invalid configuration or improper
diagnostic tool.

Regarding what you called "router tests" it is especially unclear what was
the purpose of testing against a port marked as "down". Do you expect
Linux to forward a packet to a port that is disconnected from it's IP stack?
Anyway, I would suggest starting with checking that packet forwarding
is enabled:

cat /proc/sys/net/ipv4/ip_forward

and checking the ICMP errors returned by the board to the source of the test
traffic.
