Setting LAN card options in /etc/modules.conf

Frank Gomes — Thu, 16 Oct 2003 12:59:33 GMT

I installed Redhat AS 2.1, on a rx5670, Itanium server. It is up and running.

I don't know the LAN card options to set in /etc/modules.conf file. The LAN card is from broadcomm. I need to nail the LAN card for 100baseT FULL.

Thanks.

Regards,

Frank

Check the Broadcom FAQs:

87.) How do I force speed and duplex for bcm5700 driver under Linux?
To set forced 100 Mbps full duplex:
insmod bcm5700 line_speed=100 full_duplex=1 auto_speed=0

or set the following in modules.conf

options bcm5700 line_speed=100 full_duplex=1 auto_speed=0

or use ethtool:

ethtool -s eth0 speed 100 duplex full autoneg off

Note: If the auto_speed is not set to zero if would negotiate at the speed and duplex that was set with respective parameters.

Don't forget to assign the points!

vi /etc/modules.conf
options eth0 line_speed=100 full_duplex=1

other options
line_speed=0 auto
auto_speed=0 (auto disabled) or 1 auto enabled
full_duplex=0 half

After making mods type:
ifdown eth0
ifup eth0

Then install the rpm for mii-tool and run it. It will reture the speed, negotiation, etc.
