Although most administrators will use dhcpconfig or dhcpmgr to manage DHCP services, it is also possible to manually edit the DHCP configuration database, dhcptab, by using the dhtadm command. Macros can be installed and server options can be set by using the dhtadm command.
In the first instance, dhtadm can be used to create a new dhcptab file:
# dhtadm –C
The following options can be passed to dhtadm to perform various tasks:
-A Define a macro or symbol
-B Perform batch processing
-C Create the service configuration database
-D Remove a macro or symbol
-M Update a macro or symbol
