Try autoselect, if you get 100 full, stay in autoselect. (If you force 100 full and the switch is auto, then the switch will be in 100 half !) try this: ping -c 1000 -s 1500 IP_TO_PING wait for the 1000 ping to go trough. You should not have more than 0,5% of loss (is the servers aren't overload). If it's more or equal than 0,5%, it comes from the network (cables or switches fault). Each host would be in 100 full (via autoselect to be sure the conf is ok on the switch).

Each host would be in 100 full (via autoselect to be sure the conf is ok on the switch). p I made the tests on the two boxes = 0 % packet loss. p I man an other interesting test. I try to transfert between the BSD Box p and a server located at home behind my 1MB/s ADSL Line. Here are the p results : FreeBSD box = Workstation at home : 300 kB/s p Debian box on the same network = Workstation at home : 950 kB/s. p This test confirms cleraly that there is a problem with the BSD, I guess. p Could it be a bug from the VR driver ? p Regards, p Ptitoliv At this point, a tcpdump while transfering may help. Are the debian freebsd on the same segment ? if so, are they using the same router/gateway ? did you customize/set up things, like ipfw or set specific things via sysctl ?
