Q

You must create a network device configuration file for the layered Ethernet device 
on the InfiniPath adapter. This configuration file will resemble the configuration files 
for the other Ethernet devices on the nodes. Typically on servers there are two 
Ethernet devices present, numbered as 0 (eth0) and 1 (eth1). This examples 
assumes we create a third device, eth2.

When multiple InfiniPath chips are present, the configuration for eth3, 
eth4

, and so on follow the same format as for adding eth2 in the examples 

below.

Two slightly different procedures are given below for the ipath configuration; one 
for Fedora and one for SUSE, SLES9, or SLES 10.

Many of the entries that are used in the configuration directions below are explained 
in the file sysconfig.txt. To familiarize yourself with these, please see:

/usr/share/doc/initscripts-*/sysconfig.txt

These configuration steps will cause the ipath_ether network interfaces to be 
automatically configured when you next reboot the system. These instructions are 
for the 

Fedora Core 3, Fedora Core 4 and Red Hat Enterprise Linux 4 

distributions.  

Typically on servers there are two Ethernet devices present, numbered as 0 (eth0) 
and 1 (eth1). This example assumes we create a third device, eth2.

When multiple InfiniPath chips are present, the configuration for eth3, 
eth4

, and so on follow the same format as for adding eth2 in the 

examples below.

1. Check for the number of Ethernet drivers you currently have by either one of 

the two following commands : 

 $ ifconfig -a

 $ ls /sys/class/net

As mentioned above we assume that two Ethernet devices (numbered 0 and 
1) are already present. 

2. Edit the file 

/etc/modprobe.conf

 (as root) by adding the following line:

alias eth2 ipath_ether

3. Create or edit the following file (as root). 

/etc/sysconfig/network-scripts/ifcfg-eth2
