One way to look at it. :)

Yes standard TP. Server is located same rack as the others. One fellow
from this group if I may mention him, as the last message was CC'd to the
list: Brad McConnell mentioned he had some Linux machines with Intel
EtherExpress cards connected to a 6509 switch. When he hard set the port
on the card and the switch he saw errors as well. Soon as he Auto'd both
the switch and the card in the computer all was well.
As these are the same card but running under BSD/OS, I set a port to Auto
on the switch, made sure the card was set to auto and moved the computer
to that port, took about 15 secs but they autoed to 100/full.
That was about a half hour ago and so far no errors:
5 minute input rate 127000 bits/sec, 42 packets/sec
5 minute output rate 107000 bits/sec, 40 packets/sec
103937 packets input, 42817903 bytes
Received 1 broadcasts, 0 runts, 0 giants, 0 throttles
0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored
0 watchdog, 0 multicast
0 input packets with dribble condition detected
99082 packets output, 39561280 bytes, 0 underruns
0 output errors, 0 collisions, 1 interface resets
0 babbles, 0 late collision, 0 deferred
0 lost carrier, 0 no carrier
0 output buffer failures, 0 output buffers swapped out
Generally I would start seeing input errors within the first couple of
megs of data. Looks like there might be issues with the driver for this
card under BSD/OS and having the switch side pegged to 100/full and the
card set to auto.
Leave it be for now and see how it goes.
Thanks for the reply.
