Configuring DHCP for Linux
You can manage the configuration of the Linux DHCPD service by editing the dhcpd.conf configuration file. The dhcpd.conf is
at /etc/dhcp directory of most Linux distributions. If the DHCP is not installed on your Linux server, install the Network
Infrastructure Server or similar services.
Before you start editing the dhcpd.conf file, it is recommended to back up the file. After you install the appropriate network
services, you must configure the dhcpd.conf file before you start the DHCPD service.
The DHCP configuration must include the following options:
• next-server <IP address>
Indicates the IP address of the PXE server. That is, the IP address of ASM appliance vNIC that exists on the OS Installation
network.
• filename "bootstrap.ipxe"
NOTE: For PXE service to function properly, you must specify bootstrap.ipxe for the filename.
The PXE service uses iPXE service. You must use two different bootstrap files for the PXE environment, one for the initial PXE
boot, which starts up the system to the final iPXE boot file.
To run this operation, add the following code to the dhcpd.conf file:
if exists user-class and option user-class = "iPXE" {
filename "bootstrap.ipxe";
} else {
