Chapter 6 Before You Install ESXi Many DHCP servers can PXE boot hosts. If you are using a version of DHCP for Microsoft Windows, see the DHCP server documentation to determine how to pass the next-server and filename arguments to the target machine. gPXE Example This example shows how to configure a ISC DHCP version 3.0 server to enable gPXE. allow booting; allow bootp; # gPXE options option space gpxe; option gpxe-encap-opts code 175 = encapsulate gpxe; option gpxe.bus-id code 177 = string; class "pxeclients" { match if substring(option vendor-class-identifier, 0, 9) = "PXEClient"; next-server TFTP server address; if not exists gpxe.bus-id { filename "/gpxelinux.0"; } } subnet Network address netmask Subnet Mask { range Starting IP Address Ending IP Address; } When a machine attempts to PXE boot, the DHCP server provides an IP address and the location of the gpxelinux.0 binary file on the TFTP server. The IP address assigned is in the range defined in the subnet section of the configuration file. PXELINUX (without gPXE) Example This example shows how to configure a ISC DHCP version 3.0 server to enable PXELINUX. # # DHCP Server Configuration file. # see /usr/share/doc/dhcp*/dhcpd.conf.sample # ddns-update-style ad-hoc; allow booting; allow bootp; class "pxeclients" { match if substring(option vendor-class-identifier, 0, 9) = "PXEClient"; next-server xxx.xxx.xx.xx; filename = "pxelinux.0"; } subnet 192.168.48.0 netmask 255.255.255.0 { range 192.168.48.100 192.168.48.250; } When a machine attempts to PXE boot, the DHCP server provides an IP address and the location of the pxelinux.0 binary file on the TFTP server. The IP address assigned is in the range defined in the subnet section of the configuration file. VMware, Inc. 131

Many DHCP servers can PXE boot hosts. If you are using a version of DHCP for Microsoft Windows, see the
DHCP server documentation to determine how to pass the
next-server
and
filename
arguments to the
target machine.
gPXE Example
This example shows how to configure a ISC DHCP version 3.0 server to enable gPXE.
allow booting;
allow bootp;
# gPXE options
option space gpxe;
option gpxe-encap-opts code 175 = encapsulate gpxe;
option gpxe.bus-id code 177 = string;
class "pxeclients" {
match if substring(option vendor-class-identifier, 0, 9) = "PXEClient";
next-server
TFTP server address
;
if not exists gpxe.bus-id {
filename "/gpxelinux.0";
}
}
subnet
Network address
netmask
Subnet Mask
{
range
Starting IP Address
Ending IP Address
;
}
When a machine attempts to PXE boot, the DHCP server provides an IP address and the location of the
gpxelinux.0
binary file on the TFTP server. The IP address assigned is in the range defined in the subnet
section of the configuration file.
PXELINUX (without gPXE) Example
This example shows how to configure a ISC DHCP version 3.0 server to enable PXELINUX.
#
# DHCP Server Configuration file.
#
see /usr/share/doc/dhcp*/dhcpd.conf.sample
#
ddns-update-style ad-hoc;
allow booting;
allow bootp;
class "pxeclients" {
match if substring(option vendor-class-identifier, 0, 9) = "PXEClient";
next-server xxx.xxx.xx.xx;
filename = "pxelinux.0";
}
subnet 192.168.48.0 netmask 255.255.255.0 {
range 192.168.48.100 192.168.48.250;
}
When a machine attempts to PXE boot, the DHCP server provides an IP address and the location of the
pxelinux.0
binary file on the TFTP server. The IP address assigned is in the range defined in the subnet
section of the configuration file.
