On a 10Gig interface, is 1 CRC per minute at @20,000 packets per second a problem or not?

[geoff.mossburg]

I've read on other parts of the Cisco site that CRCs should not exceed 1 in 1 million packets, but in my 10Gig scenario described in the title (10Gig interface, 1 CRC per minute at @20,000 packets per second), does that generally mean there's no problem if I'm seeing these CRCs? I think the math adds up to no more than 1 CRC every 50 seconds or so, but aren't any incrementing CRCs bad?

Regardless of the speed/interface type, if your CRC is incrementing regularly, it's bad.
