Container Record Formats

The Solaris DHCP service uses two types of DHCP containers: the dhcptab container and the DHCP network container.

The dhcptab container holds DHCP configuration data, described in the dhcptab man page. Only one instance of a dhcptab container is maintained in the DHCP service.

dhcptab records are passed between the Framework Configuration Layer and the Service Provider Layer by way of an internal structure, dt_rec_t. The include file /usr/include/dhcp_svc_public.h shows the structure.

Your public module must ensure that there are no duplicate dhcptab records. No two records can have identical key field values.

DHCP network containers contain IP address records, described in the dhcp_network man page. These containers are named to indicate the data store and the dotted IP address of the network to which the IP addresses belong, such as 10.0.0.0. Any number of DHCP network containers may exist, one for each network supported by the DHCP service.

DHCP network records are passed between the Framework Configuration Layer and the Service Provider Layer by way of an internal structure, dn_rec_t. The include file /usr/include/dhcp_svc_public.h shows the structure.

Your public module must ensure that there are no duplicate network container records. No two records can have identical key field values.
