Setting Ethernet speed 10/100/Auto

[CoolMan4227]

I have an appliance server running RedHat 6.1 (can't upgrade). I have a situation where a cable modem vendor is suppling a 10mbit connection. My system has a 10/100 auto-sencing ethernet. Under certain circumstances, I have applications that are not handling well with the mismatch of 10 & 100 speed. I need to be able to disable auto-sensing or set my ethernet to a specific speed.

I don't see any parameters for commands such as IFCONFIG to accomplish this. Any ideas?

You don't want to set your ethernet speed, you want to set your NIC speed. I don't know what you have for a NIC but most have a DOS based utility that allows you set certain parameters such as IRQ, base memory and auto sensing. Look for this disk, boot from a vanilla DOS disk and run setup from the disk supplied with the NIC.

Not able to do that. It is a Headless server. (no keyboard, monitor or floppy drive). It has a built in 7 port router, and a WAN port(Eth1) not just a NIC. That's why I was trying to control the speed of the WAN port at the OS lever rather than the NIC settings.

Thanks for the reply.

Change it at the network switch.

The Network Switch is built-in. The only control that I have is within Linux. Their are not firware or utility programs to control it. I have to be able to set it at the kernel level.

Not an easy one. Thanks for helping.

Your wan port is a nic.
