Just for your info...

I had a similar problem and support said that you should be putting
a lan_config command in /etc/inet.local. That is recommended way
to configure the ethernet device.

My inetd.local has the following

/usr/sbin/lan_config -i ee0 -s 100 -x 1

which configures it as 100 full duplex

Support told me that the console settings will not work.

It sounds like you have a DE60x style NIC (hence the ee0 name).
These cards based in the Intel 82558 (10/100 Mbps) Ethernet Interface do
not
interact correctly with the SRM console variables.

You must manually setup the speed of the card in the /etc/inet.local
file
before networking is enabled:

########################################################################
####
#########
echo "Starting local network commands (from /etc/local.inet)."
echo "Fixing Ethernet i/f speed at 100 Mb/s, full duplex,
autonegotiation
disabled."
echo "ee0 ..."
lan_config -i ee0 -a 0 -s 100 -x 1
/sbin/sleep 2
echo "Done interface ee0 ..."
/sbin/sleep 1
echo "Finished fixing Ethernet i/f speed."
echo "Finished execution of local network commands (from
/etc/local.inet)."
########################################################################
####
#########

This script was setup by Chris Jankowski of HP/Compaq/Digital Fame.

Obviously the switch port must be set at 100 full duplex for this to
work
(especially if you are using NETRain).
