That's not a particularly big number; it's half a percent of your output packets. That probably doesn't have a measurable effect on your throughput or latency. Now, that said, if you have a switch, you probably SHOULD be running full-duplex, in which case you won't have collisions. But you've got an ed card; some of those may be old enough to not handle FDX. > 2. Ierr -- seems that some input errors. What are these errors and > what can cause them? Cable troubles, NIC troubles, etc. [Un]plugging the cable can cause it. Some forms of on-wire data corruption could cause it. You've got 4 of them, over 36 million input packets. Don't worry about it. -- Matthew Fuller (MF4839) | [EMAIL PROTECTED] Systems/Network Administrator | http://www.over-yonder.net/~fullermd/ On the Internet, nobody can hear you scream. _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[EMAIL PROTECTED]"
