After you gather information and plan for DHCP service, you are ready to configure a DHCP server. You can use the DHCP Manager or the command-line utility dhcpconfig to configure a server. DHCP Manager lets you select options and specify data that is then used to create the dhcptab and network tables used by the DHCP server. The dhcpconfig utility requires you to use command-line options to specify data.
DHCP Manager, a Java™ technology-based GUI tool, provides a DHCP Configuration Wizard. The configuration wizard starts automatically the first time you run DHCP Manager on a system that is not configured as a DHCP server. The DHCP Configuration Wizard provides a series of dialog boxes that prompt you for the essential information required to configure a server: data store format, lease policy, DNS/NIS/NIS+ servers and domains, and router addresses. Some of the information is obtained by the wizard from system files, and you only need to confirm that the information is correct, or to correct information, if necessary.
When you progress through the dialog boxes and approve the information, the DHCP server daemon starts on the server system. You are then prompted to start the Add Addresses Wizard to configure IP addresses for the network. Only the server's network is configured for DHCP initially, and other server options are given default values. You can run DHCP Manager again after the initial configuration is complete to add networks and modify other server options.
See Configuring and Unconfiguring a DHCP Server Using DHCP Manager for more information about the DHCP Configuration Wizard. See About DHCP Manager for more detailed information about DHCP Manager.
The dhcpconfig utility supports options that enable you to configure and unconfigure a DHCP server, as well as convert to a new data store and import/export data to and from other DHCP servers. When you use the dhcpconfig utility to configure a DHCP server, the utility obtains information from the system files discussed in Updating System Files and Netmask Tables. You cannot view and confirm the information obtained from system files as you can with DHCP Manager. So, it is important that the system files be updated before you run dhcpconfig. You can also use command-line options to override the values dhcpconfig would obtain by default from system files. The dhcpconfig command can be used in scripts. See the dhcpconfig(1M) man page for more information.
The following table summarizes the differences between the two server configuration tools.

Chapter 14, Configuring the DHCP Service (Tasks) includes procedures you can use to configure your server with either DHCP Manager or the dhcpconfig utility.
