Hi @Stephane_Cherie,
So we can better assist you, please provide a brief description of your current setup using this link as a guide.
Make sure to describe your network configuration/topology, including any networking hardware currently in use, so we can have a clear understanding of how your devices are communicating.
Are the numbers shown changing at all or have they been stuck at those same numbers for a while?
If you reboot your Core is there any change?
