Directive without argument.  Set this dhcpd server authoritative on the domain.

clear /files/etc/dhcp3/dhcpd.conf/authoritative

Directives with integer or string argument.  Set max-lease-time to one hour:

set /files/etc/dhcp3/dhcpd.conf/max-lease-time 3600

Options are declared as a list, even for single values.  Set the domain of the network:

set /files/etc/dhcp3/dhcpd.conf/option/domain-name/arg example.org

Set two name server:

set /files/etc/dhcp3/dhcpd.conf/option/domain-name-servers/arg[1] foo.example.org
set /files/etc/dhcp3/dhcpd.conf/option/domain-name-servers/arg[2] bar.example.org

Create the subnet 172.16.0.1 with 10 addresses

clear /files/etc/dhcp3/dhcpd.conf/subnet[last() + 1]
set /files/etc/dhcp3/dhcpd.conf/subnet[last()]/network 172.16.0.0
set /files/etc/dhcp3/dhcpd.conf/subnet[last()]/netmask 255.255.255.0
set /files/etc/dhcp3/dhcpd.conf/subnet[last()]/range/from 172.16.0.10
set /files/etc/dhcp3/dhcpd.conf/subnet[last()]/range/to 172.16.0.20

Create a new group “foo” with one static host.  Nodes type and address are ordered.

ins group after /files/etc/dhcp3/dhcpd.conf/subnet[network='172.16.0.0']/*[last()]
set /files/etc/dhcp3/dhcpd.conf/subnet[network='172.16.0.0']/group[last()]/host foo
set /files/etc/dhcp3/dhcpd.conf/subnet[network='172.16.0.0']/group[host='foo']/host/hardware/type "ethernet"
set /files/etc/dhcp3/dhcpd.conf/subnet[network='172.16.0.0']/group[host='foo']/host/hardware/address "00:00:00:aa:bb:cc"
set /files/etc/dhcp3/dhcpd.conf/subnet[network='172.16.0.0']/group[host='foo']/host/fixed-address 172.16.0.100
