Hi,
as you see in the picture below the traffic monitoring tool is not working perfectly after I upgrade my CCR1036-12G-4s router board to v6.43.2.

I can’t determine if this cut affecting the internet or it is just reading problem.
one thing to mention in here that I am using the router board as load balancing device merging three lines from three different resources. this traffic monitoring for the LAN (the sum of the three lines).

thanks for your support in advance,
