I don't know any reason why one of the ethernet ports becomes half-duplex. Here is its detail: em1: flags=8843 mtu 1500 options=b inet 60.1.2.3 netmask 0xfffffffc broadcast 220.233.99.39 ether 00:04:23:bc:3a:d1 media: Ethernet autoselect (10baseT/UTP ) status: active em2: flags=8843 mtu 1500 options=b inet 10.1.10.1 netmask 0xffffff00 broadcast 10.1.10.255 ether 00:04:23:bc:3a:d2 media: Ethernet autoselect (1000baseTX ) status: active This network card is a Quat Port Intel card. Is there any way I can "reset" it to full-duplex and 1000baseT without close down the network connection on em1? I know I can use following command to change it: ifconfig em1 media 100baseTX mediaopt full-duplex but if this not work, it will close down the entire internet connection, which I try to avoid. Thanks S
