A service provider has forced all of their switch ports to 100/

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!
