Hi,
I found that there was a network jam on two Jetson Xavier NX devices directly connected; This is the result of my two-way test using iperf tool:
device info:
$ jetson_release
- NVIDIA Jetson Xavier NX (Developer Kit Version)

$ sudo ethtool eth0
Settings for eth0:

one Jetson Xavier NX device(192.168.1.3):
iperf3 -s
iperf3 -c 192.168.1.101 -p 5201 -t 100
another Jetson Xavier NX device(192.168.1.101):
iperf3 -s
iperf3 -c 192.168.1.3 -p 5201 -n 445440000000
But no problem was found through the net switch connection.
Is it a well-known issue?
