4.4.3.1.2 DHCP Client (Optional)

A DHCP client can be used if you need to prepare a diskless machine with an

IB driver. See Step 8 under “Example: Adding an IB Driver to initrd (Linux)”.

In order to use a DHCP client identifier, you need to first create a configuration file that defines

the DHCP client identifier

Then run the DHCP client with this file using the following command:

dhclient –cf <client conf file> <IB network interface name>

Example of a configuration file for the ConnectX (PCI Device ID 26428), called

dhclient.conf:

# The value indicates a hexadecimal number

interface "ib1" {

send dhcp-client-identifier

ff:00:00:00:00:00:02:00:00:02:c9:00:00:02:c9:03:00:00:10:39;

}

Example of a configuration file for InfiniHost III Ex (PCI Device ID 25218), called

dhclient.conf:

# The value indicates a hexadecimal number

interface "ib1" {

send dhcp-client-identifier

20:00:55:04:01:fe:80:00:00:00:00:00:00:00:02:c9:02:00:23:13:92;

}

In order to use the configuration file, run:

host1# dhclient –cf dhclient.conf ib1
