Hello,
I checked and your observation is true. Maybe 1000 times is not enough
. But I observed that if I scan the network with nmapfe during the
ping test, the ethernet port starts loosing packets.
I used the following configuration:
laptop eth0: 192.168.2.9
ts-7300 eth1: 192.168.2.10
from the laptop I pinged the board and during this test I ran the
following command on the laptop:
nmap -sT -F -PT -n 192.168.2.0/24
Regards,
Mahdi
