However, I'm now getting lots of "Oerrs" reported by netstat -I when trying to send to another box running at 100Mbit on the same switch. When sending to a 10bt only box on the switch, all seems fine, and I'm getting xfer speeds at ~900K / sec. But when talking to another box running 100tx, I'm getting ~30 -> ~75K / s. When I reverse the data flow (sending from Sparc Ultra 1 to the FreeBSD box), I'm getting ~3.5Mbyte / second. All of the ports on the switch are set for autoconfigure. The BSD box autoconfigs 100tx at probe / attach time. It only seems to support simplex, whereas the sparc configs full duplex. Any pointers / suggestions? Thanks!
