DHCP Command-Line Utilities

All DHCP management functions can be performed using command-line utilities. You can run them if you are logged in as root, or as a user assigned to the DHCP Management profile. See Setting Up User Access to DHCP Commands.

The following table lists the utilities and describes the purpose of each utility.

Table 7–2 DHCP Command-Line Utilities


Description and Purpose 


The DHCP service daemon. It provides command-line arguments that allow you to set several runtime options.


Used to configure and unconfigure a DHCP server. This utility enables you to perform many of the functions of DHCP Manager from the command line. It is primarily intended for use in scripts for sites that want to automate some configuration functions. dhcpconfig collects information from the server system's network topology files to create useful information for the initial configuration.


Used to add, delete, and modify configuration options and macros for DHCP clients. This utility lets you edit the dhcptab indirectly, which ensures the correct format of the dhcptab. You should not directly edit the dhcptab.


Used to manage the DHCP network tables. You can use this utility to add and remove IP addresses and networks under DHCP management, modify the network configuration for specified IP addresses, and display information about IP addresses and networks under DHCP management. 

Role-Based Access Control for DHCP Commands

Security for the dhcpconfig, dhtadm, and pntadm commands is determined by role-based access control (RBAC) settings. By default, the commands can be run only by root. If you want to be able to use the commands under another user name, you must assign the user name to the DHCP Management profile as described in Setting Up User Access to DHCP Commands.
