If you select the port parameters manually (i.e. disable autoselect), then you must do that on _both_ sides. Auto-negotiation only works correctly if both sides are using it. > This is the ifconfig output: > > fxp0: flags=18843 mtu 1500 > options=48 > inet 112.15.128.88 netmask 0xffffff00 broadcast 112.15.128.255 > inet6 fe80::208:c7ff:fe5b:54f2%fxp0 prefixlen 64 scopeid 0x2 > ether 00:08:c7:5b:54:a5 > media: Ethernet autoselect (10baseT/UTP) > status: active That means autoselect is enabled, so you have to enable it on your switch, too. Otherwise disable it on the computer and select the port parameters (speed and duplex mode) manually there, too. By the way, the above output indicates that your NIC's auto-negotiation has selected half-duplex. You said that your switch is set to full-duplex. So there is a mismatch which explains why you are getting collisions. Fix your port settings, then the collisions will go away. Best regards Oliver -- Oliver Fromme, secnetix GmbH & Co.
