View Full Version : How do you switch from full-duplex to half-duplex
July 12th, 2009, 17:06
I would like to see if half-duplex would speed up my isp connection. The set up here is cable modem to router to freebsd box.
I want my freebsd box to use half-duplex
thanks in advance for any link or know how.
check ifconfig - look for mediaopt
example from the man
ifconfig xl0 media 10baseTX mediaopt full-duplex

No manual entry for ifconfig
I tried that code
unknown media subtype: 10baseTX

There has to be man page for ifconfig, also you have to check the man page for your NIC driver. E. g. man vr (vr).

If you used the minimal install the man pages aren't installed. Have a look here ifconfig.

Next command show supported modes for your network card:
ifconfig -m fxp0
media 100baseTX mediaopt full-duplex
media 10baseT/UTP mediaopt full-duplex
media 100baseTX mediaopt hw-loopback
Change settings with next command:
ifconfig fxp0 media 10baseT/UTP mediaopt full-duplex
