.SH DESCRIPTION
.sp
.LP
\fBdhtadm\fR manages the Dynamic Host Configuration Protocol (\fBDHCP\fR)
service configuration table, \fBdhcptab\fR. You can use it to add, delete, or
modify \fBDHCP\fR configuration macros or options or view the table. For a
description of the table format, see \fBdhcptab\fR(4).)
.sp
.LP
The \fBdhtadm\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
After you make changes with \fBdhtadm\fR, you should issue a \fBSIGHUP\fR to
the DHCP server, causing it to read the \fBdhcptab\fR and pick up the changes.
Do this using the \fB-g\fR option.
.SH OPTIONS
.sp
.LP
One of the following function flags must be specified with the \fBdhtadm\fR
command: \fB-A\fR, \fB-B\fR, \fB-C\fR, \fB-D\fR, \fB-M\fR, \fB-P\fR or
\fB-R\fR.
.sp
.LP
The following options are supported:
.sp
.ne 2
.na
\fB\fB-A\fR \fR
.ad
.RS 27n
Add a symbol or macro definition to the \fBdhcptab\fR table.
.sp
The following sub-options are required:
.sp
.ne 2
.na
\fB\fB-d\fR \fIdefinition\fR\fR
.ad
.RS 18n
Specify a macro or symbol definition.
.sp
\fIdefinition\fR must be enclosed in single quotation marks. For macros, use
the form \fB-d\fR
\fB\&':\fIsymbol\fR=\fIvalue\fR:\fIsymbol\fR=\fIvalue\fR:'\fR. Enclose a
\fIvalue\fR that contains colons in double quotation marks. For symbols, the
definition is a series of fields that define a symbol's characteristics. The
fields are separated by commas. Use the form \fB-d\fR
\fB\&'\fIcontext\fR,\fIcode\fR,\fItype\fR,\fIgranularity\fR,\fImaximum\fR'\fR.
See \fBdhcptab\fR(4) for information about these fields.
.RE

.sp
.ne 2
.na
\fB\fB-m\fR \fImacro_name\fR\fR
.ad
.RS 18n
Specify the name of the macro to be added.
.sp
The \fB-d\fR option must be used with the \fB-m\fR option. The \fB-s\fR option
cannot be used with the \fB-m\fR option.
.RE

.sp
.ne 2
.na
\fB\fB-s\fR \fIsymbol_name\fR\fR
.ad
.RS 18n

.RE

.RE

.sp
.ne 2
.na
\fB\fB-B\fR\fR
.ad
.RS 27n
Batch process \fBdhtadm\fR commands. \fBdhtadm\fR reads from the specified file
or from standard input a series of \fBdhtadm\fR commands and execute them
within the same process. Processing many \fBdhtadm\fR commands using this
method is much faster than running an executable batchfile itself. Batch mode
is recommended for using \fBdhtadm\fR in scripts.

.LP
\fBExample 2 \fRAdding a Symbol Definition
.sp
.LP
The following command adds a \fBVendor\fR option symbol definition for a new
symbol called \fBMySym\fR to the \fBdhcptab\fR table in the \fBSUNWfiles\fR
resource in the \fB/var/mydhcp\fR directory:

.sp
.in +2

.fi
.in -2
.sp

.LP
\fBExample 3 \fRAdding a Macro Definition
.sp
.LP
The following command adds the \fBaruba\fR macro definition to the
\fBdhcptab\fR table. Note that symbol/value pairs are bracketed with colons
(\fB:\fR).

.LP
\fBExample 4 \fRModifying a Macro Definition
.sp
.LP
The following command modifies the \fBLocale\fR macro definition, setting the
value of the \fBUTCOffst\fR symbol to 18000 seconds. Note that any macro
definition which includes the definition of the \fBLocale\fR macro inherits
this change.

.sp

.in -2
.sp

.LP
\fBExample 6 \fRAdding a Symbol to a Macro
.sp
.LP
The following command adds the \fBHostname\fR symbol to the \fBaruba\fR macro.
Note that the \fBHostname\fR symbol takes no value, and thus requires the
special value \fB_NULL_VALUE_\fR. Note also that any macro definition which
includes the definition of the \fBaruba\fR macro inherits this change.

.sp

.fi
.in -2
.sp

.LP
\fBExample 8 \fRDeleting a Symbol Definition
