5.2. Configuring network-scripts
A typical interface network-script (e.g. eth0) on RHEL 6.X looks like the following:
# file: /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE="eth0"
HWADDR=00:30:48:32:6A:AA
ONBOOT="yes"
NM_CONTROLLED="no"
BOOTPROTO="static"
IPADDR=10.192.167.111
NETMASK=255.255.240.0
In the case of DHCP addressing the last two lines should be removed and
BOOTPROTO="static" should be changed to BOOTPROTO="dhcp"
The
ifcfg-ethX
files have to be created manually. They are required for bringing the
interfaces up and down and attribute the desired IP addresses.
5.3. Creating network-scripts
To spot the new interfaces, make sure the driver is unloaded first. To that point
ifconfig -a |
grep HWaddr
should display all non-chelsio interfaces whose drivers are loaded, whether the
interfaces are up or not.
[root@host~]# ifconfig -a | grep HWaddr
eth0 Link encap:Ethernet HWaddr 00:30:48:32:6A:AA
Then load the driver using the
modprobe cxgb4
command (for the moment it does not make
any difference whether we are using NIC-only or the TOE-enabling driver). The output of
ifconfig should display the T5/T4 interfaces as:
[root@host~]# ifconfig -a | grep HWaddr
eth0 Link encap:Ethernet HWaddr 00:30:48:32:6A:AA
eth1 Link encap:Ethernet HWaddr 00:07:43:04:6B:E9
eth2 Link encap:Ethernet HWaddr 00:07:43:04:6B:F1
On earlier versions of RHEL the NETMASK attribute is named IPMASK. Make sure
you are using the right attribute name.
