Configuring the QLogic 8100 Series Adapter NIC function in RHEL 5 
environments can be accomplished using the following built-in utilities and 
functions:



ethtool—An interface that displays and configures QLogic 8100 Series 
Adapter NIC function parameters. Use ethtool to configure offload settings 
and view network interface statistics. Configuration changes that you make 
with ethtool are lost if the server reboots. To make persistent configuration 
changes, edit the file /etc/sysconfig/network-scripts/
ifcfg-ethX.



ifconfig—A utility that configures a adapter network interface with certain 
parameters such as IP address, subnet mask, or jumbo frames. Ifconfig also 
displays currently active network interfaces. Any configuration changes you 
make with ifconfig are lost if the server reboots. To make persistent 
configuration changes, edit the file /etc/sysconfig/
network-scripts/ifcfg-ethX.



modprobe—A utility that loads and unloads a kernel module, such as the 
QLogic NIC driver (qlge). modprobe also changes the values of various 
driver parameters for the qlge driver. Any configuration changes that you 
make with modprobe are lost if the server reboots. To make persistent 
configuration changes, edit the file /etc/modprobe.conf and create a 

new RAMDISK image.



ifenslave—A user-level control program that manages bonding interfaces.



vconfig—A user level utility that creates VLAN interfaces.

The following sections describe the use of these utilities and functions.
