Hello

How can I disable broadcom network devices in IBM e-servers (X3550) ???

1) Using BIOS
2) Using commands

Can anyone please let me know how this should be done???

What do you mean by disable? Removing the device or preventing it from connecting to a netwotk?

You did not tell us your distribution, but assuming it is RedHat or SuSe, edit /etc/network/interfaces and comment the right eth0 device.

Solution 2:
Create/edit the udev rule in /etc/udev/rules.d/70-net... (complete de name with tab)

To just disable internet and shut the interface down: ifdown <interface name>

I meant not allowing the interface to connect with the network by disabling.Also I m using Redhat .
I tried your first solution,it didnt work.
Will try the next one and let you know the status.

Thanks a lot!!!

In my BIOS...

Assuming that you have an on-board LAN device, there should be a post in the BIOS settings to disable the chip function; mine is "On-chip MAC Lan" Look for something similar and disable it.

However, since this is a server and network connection is assumed, there may be no BIOS control of the LAN. Your IBM system/motherboard documentation might tell you more.

If you have a separate LAN card, there should be nothing in the BIOS about it as a LAN; it should be found as one of the PCI devices. Simply remove the LAN card.

RedHat has configured the device. In my openSUSE 11.1 installation, I can open the configuration process and re-configure or disable a LAN device and its connection. I assume that you can do the same in RedHat. I don't know which RedHat you are using, but RedHat is generally well documented. This is for RHEL 5.

Of course you can edit files, but I assume that configuring the installation would be more logical and create fewer difficulties in the end than by editing.
