Chapter I. Chelsio Unified Wire

[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 T4 interfaces now:

[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

eth3 Link encap:Ethernet HWaddr 00:07:43:04:6B:F9

eth4 Link encap:Ethernet HWaddr 00:07:43:04:6C:01

For each T4 interface you can write a configuration file in /etc/sysconfig/network-scripts.

The ifcfg-eth1 could look like:

# file: /etc/sysconfig/network-scripts/ifcfg-eth1

DEVICE="eth1"

HWADDR=00:07:43:04:6B:E9

ONBOOT="no"

NM_CONTROLLED="no"

BOOTPROTO="static"

IPADDR=10.192.167.112

NETMASK=255.255.240.0

From now on, the eth1 interface of the T4 adapter can be brought up and down through the

ifup eth1 and ifdown eth1 commands respectively. Note that it is of course not compulsory

to create a configuration file for every interface if you are not planning to use them all.

5.3. Checking Link

Once the network-scripts are created for the T4 interfaces you should check the link i.e. make

sure it is actually connected to the network. First, bring up the interface you want to test using

ifup eth1.

You should now be able to ping any other machine from your network provided it has ping

response enabled.
