.SH DESCRIPTION
.sp
.LP
The \fBdhcpconfig\fR command is used to configure and manage the Dynamic Host
Configuration Protocol (DHCP) service or BOOTP relay services. It is intended
for use by experienced Solaris system administrators and is designed for ease
of use in scripts. The \fBdhcpmgr\fR utility is recommended for less
experienced administrators or those preferring a graphical utility to configure
and manage the DHCP service or BOOTP relay service.
.sp
.LP
The \fBdhcpconfig\fR command can be run by root, or by other users assigned to
the DHCP Management profile. See \fBrbac\fR(5) and \fBuser_attr\fR(4).
.sp
.LP
\fBdhcpconfig\fR requires one of the following function flags: \fB-D\fR,
\fB-R\fR, \fB-U\fR, \fB-N\fR, \fB-C\fR, \fB-X\fR, \fB-I\fR, \fB-P\fR or
\fB-S\fR.
.sp
.LP
The \fBdhcpconfig\fR menu driven mode is supported in Solaris 8 and previous
versions of Solaris.
.SS "Where dhcpconfig Obtains Configuration Information"
.sp
.LP
\fBdhcpconfig\fR scans various configuration files on your Solaris machine for
information it can use to assign values to options contained in macros it adds
to the \fBdhcptab\fR configuration table. The following table lists information
\fBdhcpconfig\fR needs, the source used, and how the information is used:
.sp

.sp
.TS
box;
l | l | l
l | l | l .
\fIInformation\fR	\fISource\fR	\fIWhere Used\fR
_
Timezone	System date, timezone settings	\fBLocale\fR macro
DNS parameters	\fBnsswitch.conf\fR, \fB/etc/resolv.conf\fR	Server macro
NIS parameters	System domainname, \fBnsswitch.conf\fR, NIS	Network macros
Subnetmask	T{
Network interface, \fBnetmasks\fR table in nameservice
T}	Network macros
.TE

.sp
.LP
If you have not set these parameters on your server machine, you should do so
before configuring the DHCP server with \fBdhcpconfig\fR. Note that if you
specify options with the \fBdhcpconfig \fR\fB-D\fR command line, the values you
supply override the values obtained from the system files.
.SH OPTIONS
.sp
.LP
The following options are supported:
.sp
.ne 2
.na
\fB\fB-C\fR\fR
