The assumption being that without specifying media-opt, you get half-duplex on 10baseT/UTP e.g. cage# ifconfig rl0 rl0: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 inet 10.0.0.1 netmask 0xffffff00 broadcast 10.0.0.255 inet6 fe80::250:fcff:fe05:2624%rl0 prefixlen 64 scopeid 0x2=20 ether 00:50:fc:05:26:24=20 media: autoselect (none) status: active supported media: autoselect 100baseTX <full-duplex> 100baseTX 10baseT/UTP <full-duplex> 10baseT/UTP 100baseTX <hw-loopback> cage# ifconfig rl0 media 10baseT/UTP cage# ifconfig rl0 rl0: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 inet 10.0.0.1 netmask 0xffffff00 broadcast 10.0.0.255 inet6 fe80::250:fcff:fe05:2624%rl0 prefixlen 64 scopeid 0x2=20 ether 00:50:fc:05:26:24=20 media: 10baseT/UTP status: active supported media: autoselect 100baseTX <full-duplex> 100baseTX 10baseT/UTP <full-duplex> 10baseT/UTP 100baseTX <hw-loopback> cage#=20 ---Mike Mike Tancsa (mdtancsa@sentex.net) =09 Sentex Communications Corp, =09 Waterloo, Ontario, Canada "Given enough time, 100 monkeys on 100 routers=20 could setup a national IP network."
