Ethernet 0 Stops after some time

Hi

I am working on custom board based on S7G2 with ssp 1.4.0.

I have 2 ethernets in my custom board.

After flash, when the board is powered on, ping successfully works for both Ethernets.

After some time Ethernet 0 gets stops but  Ethernet 1 ping does not stop.It pings successfully and continuous.

I have attached my ethernet configurator file.

What could be the issue with Ethernet 0.Please suggest

Thanks and Regards
