I am running iperf for more than 11 hours without any problem. More than 450GB were transmitted. The NIC is connected to old 100Mbps switch and using first port (em0) in shared mode for remote management. em0: flags=8843 metric 0 mtu 1500 options=4219b ether 00:25:90:73:d1:76 inet xx.xx.xx.xx netmask 0xffffff80 broadcast xx.xx.xx.xx media: Ethernet autoselect (100baseTX ) status: active The iperf command on Supermicro side was: # iperf -c xx.xx.xx.yy --format k -m -p 999 -t 1800 The other side (Cisco UCS C200 M2) was: # iperf -s -p 999 Server listening on TCP port 999 TCP window size: 64.0 KByte (default) ------------------------------------------------------------ [ 5] local 94.124.105.117 port 999 connected with 94.124.105.115 port 29787 [ 5] 0.0-1799.8 sec 19.5 GBytes 93.0 Mbits/sec [ 4] local 94.124.105.117 port 999 connected with 94.124.105.115 port 44792 [ 4] 0.0-1799.9 sec 19.5 GBytes 93.1 Mbits/sec [ 5] local 94.124.105.117 port 999 connected with 94.124.105.115 port 11327 [ 5] 0.0-1799.9 sec 19.5 GBytes 93.0 Mbits/sec Both sides are running FreeBSD 8.3-RELEASE amd64 Let me know if I should run iperf with different options to better simulate your conditions where your NIC hangs.
