What you consider as "acceptable" CRC error rate?

Hi there,

What do you consider acceptable CRC error rate for 10, 40 and 100G?

I have a couple of 40G ports in a LAG which have around 0,000047% CRC error rate -a bit different on each port- and I don't like it (Mainly because all ports are usually at a pure 0% CRC error rate, as we don't have long haul fibers).

But on the other side, this port has significantly more traffic than other ports.

I'm pretty sure there is something wrong -because it started happening today- but I'm curious about what you you would consider normal or acceptable in your infrastructure.

Cheers!
