Another shot--- Anyone know how to see L2 CRC errors on an Ethernet interface?

I've scoured netstat, but found nothing (from what I've known of it it's all Layer 3 anyway). I googled and came up rather empty ("FCS error openBSD", "ethernet frame CRC errors openbsd", etc.) . The purpose for this is to deduce duplex-mismatch problems on Fast Ethernet interfaces where you only have visibility/control over one side of the Ethernet connection. If there is no way to specifically view counters like this are there other counters (or a combination of counters) I can look to that would definitively show a duplex-mismatch situation (as in no false-positives) ? I know there are error counters in "netstat -i" but are those always going to mean there is a duplex mismatch problem (it just seems there's a lack of detail there so those errors could result from a variety of issues)? Is there anything to be gleaned from a "netstat -s" to show this also? I appreciate any suggestions, Dan Farrell Applied Innovations Corp. [EMAIL PROTECTED]
