Hard-coding NIC to 100/full

[John Garrott]

I am setting up a Proliant blade server running Fedora Core1 as the repository for RHL Enterprise 3.0 ES binaries so that we can push out new servers using Proliant RDP (Rapid Deployment). The networking keeps flaking out; I am intermittantly losing connectivity. I suspect this is due to problems with auto-negotiation between the NIC and the switch port. I want to hard-code the NIC to 100/full but I can't find any reference to a utility to use (something like "lanadmin" in HP-UX). What is the equivalent utility in Red Hat Linux (Fedora Core1)?

Look into the mii-tool command. You will probably want the -F option. Hope that helps!

Most of the kernel-drivers for network cards also have the ability to lock the speed at driver initilisation.

modinfo -p

is your friend!

That, combined with an 'options

hey John,

Simple..

You cannot set the duplex/speed for the console nic from within the mui. You must set it by modifying the /etc/modules.conf.
For instance, RTL8139 NICs are set at the console by the following string in /etc/modules.conf (one line):

options 8139too line_speed=100 auto_speed=0 full_duplex=1


u can check it by using

ethtool eth0
dmesg | grep eth
