A minor detail - I think you *must* have autoneg set first - it applies them one after the other, in my experience.
ETHTOOL_OPTS="autoneg off speed 100 duplex full"
mark
in this case though, it is gigE so dont use 100
it was used cause cisco typically should be hard set for speed and duplex so you never have to guess or worry
realistically speed auto duplex auto
gigE is supposed to be smarter
rudi,
you can play with ethtool without having stuff in the ifcfg file
it isnt absolutely necessary to have that stuff in an ifcfg- interface file
those things in the line above are for "boot time" or when up'n the interface and wanting it always the same
