Ethernet Use cases Ping Statistics

akhil_k_appu — Wed, 12 Oct 2022 08:51:55 GMT

Hi,

When we first tried the A53 slow path ethernet use case, the initial ping status was 100% successful, but from yesterday onwards, the ping status returns 25% success rate. Does this affect how the test case runs? What could be the issue behind it? Adding both the console logs for your reference:

Hi,

we are using Linux BSP 32.0 that comes with GoldVIP 1.3 Image.

We are having similar issue with GMAC0 port as well. The internet connection is not accessible at times. It's acting very strange. We have tried rebooting the device, but the internet connection in the device starts and stops randomly (Ping statistics- 100% packet loss). There is no problem with the ethernet internet connection as I tried the same with my laptop and there seems to be no issue.

What could be the issue here?

Now issue is solved @Bio_TICFSL thank you for response.
