Forcing the NIC interface to 100 Mbps Full Duplex

AFAIK, for e1000 you should use

options e1000 Speed=100,Duplex=Full

Another alternate for RHAS3 is edit your /etc/sysconfig/network-scripts/ifcfg-eth0[1,2]

add this line:

ETHTOOL_OPTS="speed 100 duplex full autoneg off"

The network script checks for the variable ETHTOOL_OPTS and will set your duplex for you. This may work with RHAS2.1, depending on the update version you are running

Great! I will try that and let you know.

Thanks,

Hi, where exactly do you place this line in the eth0 file when using VI editor. 

ETHTOOL_OPTS="speed 100 duplex full autoneg off"

I have tried placing it at the end (looks like the end) and saving it but it does not make any changes,..  THank You
