How do I force a bcm5700 NIC to Full Duplex on a SuSE system?
 

Hello,

I am trying to force a NIC to negotiate with a 10/100/1000 Full switch that the powers that be do not want to configure for auto. They have configured the port for 1GB Full and the SuSE Linux 8.0 system is negotiating to 100/Half.

I suspect that configuring the switch to auto negotiate will take care of the problem, but that is not desirable. The network administrator feels that forcing 1GB/Full is more reliable.

I have ensured that there are functional cat 5e cables.

The NIC is a bcm5700 NIC in a fully operational HP DL 380 G3 server.

Any advice would be greatly appreciated. I see where some NIC settings can get forced in the /etc/modules.conf file, but I am a newbie to making changes to that particular file and obviously want to be very careful. Yast2 is not useful for this particular problem.

Thanks!

use ethtool. keep autoneg on.
