Sh int XXX counters err
Dont let it auto negotiate, make sure You manually set speed with the provider.
Make sure that broadcast you are using is private , for you and the provider. In case you are sharing that segment with others, collisions might happen thus you'll likely end up retransmitting it but not because of a l1 issue but the way the segment is saturated.. Btw, I wouldn't peer with an ISP using Ethernet, only on some DC scenarios.
Best luck
