First of all try to compare isp data with what you see on ethernet
interface connected to that isp:
ip link show -s dev ethX
You should get something like this:
RX: bytes packets errors dropped overrun mcast
714301652 713443 0 0 0 3494
TX: bytes packets errors dropped carrier collsns
79328329 501677 0 0 2 0
Stats show actual data sent/received (since reboot) including layer2
headers. Gathered data should exacly match your isp stats.
Best regards,
