Re: Using sysconfig or the command line to change nic speed and duplex settings Here's a tidbit I found in CP SecureKnowledge. Solution ID: sk26592 This is for a 1 gb nic. If it's a 100 mhz, drop a zero. modify the /etc/modules.conf file by adding this line. option e1000 Duplex=2,2,2 Speed=1000, 1000, 1000 I'm a bit puzzled because this is what my modules.conf looks like now. alias eth0 e100 alias eth1 e100 alias scsi_hostadapter sym53c8xx alias scsi_hostadapter cpqarray alias scsi_hostadapter1 sym53c8xx alias usb-controller usb-ohci |
