A service provider has forced all of their switch ports to 100/ full. I need to do the same on a box running archlinux x86_64 w/kernel 2.6.22- ARCH and the Intel e1000 driver.
I edited /etc/modprobe.conf to contain these lines:
e1000 Speed=100,100,100,100 e1000 Duplex=2,2,2,2
However, the messages in /var/log/kernel.log indicate the interfaces are still coming up as 100/half which implies they are still attempting to autonegotiate and failing therefore defaulting to 100 (which can be sensed) and half-duplex (which can't be sensed, so this is the default).
What's the best way to force the driver into 100/full on boot?
I have a similar situation at school, except I'm forced to 10/full :( I use ethtool in /etc/rc.local. This may or may not work for you, depending if you can successfully DHCP at 100/half. In this case add the ethtool line in /etc/rc.d/network before you attempt to DHCP.
ethtool -s INTERFACE speed 100 duplex full autoneg off
My box also had a Broadcom NIC in it which did not support any options via modprobe.conf so I had to use your suggestion. I ended up editing / etc/rc.local like so: # this forces the built-in broadcom NIC to 100/full mii-tool --force=100baseTx-FD eth0 I'm glad both of you chose to respond!
