Then run \ **makedhcp**\ with a noderange or the \ **-a**\ option. This will inject DHCP configuration data pertinent to the specified nodes.
With ISC DHCP, Linux node entries are updated through OMAPI. With Kea DHCP, node reservations are rendered into the Kea JSON configuration, validated, and the Kea service is restarted.
With ISC DHCP, Linux node entries are updated through OMAPI and ``omshell``.
With Kea DHCP, xCAT stores node reservations in the Kea JSON configuration and,
when the Kea Control Agent and host-commands hook are enabled, performs live
reservation add and delete operations through the Kea control API. If the live
control path is unavailable, xCAT validates the updated Kea configuration and
restarts the Kea services.

The \ **makedhcp**\ command will automatically restart the dhcp daemon after this operation.
This option will replace any existing configuration file (making a backup of it first).
For Linux systems using ISC DHCP, the file will include network entries as well as certain general parameters such as a dynamic range and omapi configuration.
For Linux systems using Kea DHCP, the generated files are ``/etc/kea/kea-dhcp4.conf``, ``/etc/kea/kea-dhcp6.conf`` when IPv6 networks are configured, and ``/etc/kea/kea-dhcp-ddns.conf`` when DDNS is enabled.
For Linux systems using Kea DHCP, the generated files are ``/etc/kea/kea-dhcp4.conf``, ``/etc/kea/kea-dhcp6.conf`` when IPv6 networks are configured, ``/etc/kea/kea-ctrl-agent.conf`` when the Kea Control Agent is enabled, and ``/etc/kea/kea-dhcp-ddns.conf`` when DDNS is enabled.
For AIX systems the file will include network entries.
On AIX systems, if there are any non-xCAT entries in the existing configuration file they will be preserved and added to the end of the new configuration file.
