12 13 The \fB/etc/dhcp/inittab\fR and the \fB/etc/dhcp/inittab6\fR files contain
13 14 information about the Dynamic Host Configuration Protocol (\fBDHCP\fR) options,
14 15 which are network configuration parameters passed from \fBDHCP\fR servers to
15 16 \fBDHCP\fR clients when a client machine uses \fBDHCP\fR. Since many
16 17 \fBDHCP\fR-related commands must parse and understand these \fBDHCP\fR options,
17 18 this file serves as a central location where information about these options
18 19 may be obtained.
19 20 .sp
20 21 .LP
21 22 The \fBDHCP\fR \fBinittab\fR and \fBinittab6\fR files provide three general
22 23 pieces of information:
23 24 .RS +4
24 25 .TP
25 26 .ie t \(bu
26 27 .el o
27 28 A mnemonic alias, or symbol name, for each option number. For instance, option
28 29 12 is aliased to the name \fBHostname\fR. This is useful for \fBDHCP\fR-related
29 30 programs that require human interaction, such as \fBdhcpinfo\fR(1).
30 31 .RE
31 32 .RS +4
32 33 .TP
33 34 .ie t \(bu
34 35 .el o
35 36 Information about the syntax for each option. This includes information such as
36 37 the type of the value, for example, whether it is a 16-bit integer or an
37 38 \fBIP\fR address.
38 39 .RE
39 40 .RS +4
40 41 .TP
41 42 .ie t \(bu

43 44 The policy for what options are visible to which \fBDHCP\fR-related programs.

47 48 If you make any changes to the \fB/etc/dhcp/inittab\fR file, note that only
48 49 additions of or changes to \fBSITE\fR options are preserved during upgrade. For
49 50 \fB/etc/dhcp/inittab6\fR, no options are preserved during upgrade.
50 51 .sp
51 52 .LP
52 53 The \fBVENDOR\fR options defined here are intended for use by the Solaris
53 54 \fBDHCP\fR client and \fBDHCP\fR management tools. The \fBSUNW\fR vendor space
54 55 is owned by Sun, and changes are likely during upgrade. If you need to
55 56 configure the Solaris \fBDHCP\fR server to support the vendor options of a
56 57 different client, see \fBdhcptab\fR(4) for details.
57 58 .sp
58 59 .LP
59 60 Each \fBDHCP\fR option belongs to a certain category, which roughly defines the
60 61 scope of the option; for instance, an option may only be understood by certain
61 62 hosts within a given site, or it may be globally understood by all \fBDHCP\fR
62 63 clients and servers. The following categories are defined; the category names
63 64 are not case-sensitive:
64 65 .sp
65 66 .ne 2
66 67 .na
67 68 \fB\fBSTANDARD\fR\fR
68 69 .ad
69 70 .RS 12n
70 71 All client and server \fBDHCP\fR implementations agree on the semantics. These
71 72 are administered by the Internet Assigned Numbers Authority (\fBIANA\fR). These
72 73 options are numbered from \fB1\fR to \fB127\fR for IPv4 DHCP, and \fB1\fR to
73 74 \fB65535\fR for DHCPv6.
74 75 .RE
75 76

77 78 .ne 2
78 79 .na
79 80 \fB\fBSITE\fR\fR
80 81 .ad
81 82 .RS 12n
82 83 Within a specific site, all client and server implementations agree on the
83 84 semantics. However, at another site the type and meaning of the option may be
84 85 quite different. These options are numbered from \fB128\fR to \fB254\fR for
85 86 IPv4 DHCP. DHCPv6 does not support site options.

93 94 .RS 12n
94 95 Each vendor may define \fB254\fR options (65536 for DHCPv6) unique to that
95 96 vendor. The vendor is identified within a \fBDHCP\fR packet by the "Vendor
96 97 Class" option, number \fB60\fR (number \fB17\fR for DHCPv6). An option with a
97 98 specific numeric identifier belonging to one vendor will, in general, have a
98 99 type and semantics different from that of a different vendor. Vendor options
99 100 are "super-encapsulated" into the vendor field number \fB43\fR, as defined in
100 101 \fIRFC 2132\fR for IPv4 DHCP, and number \fB17\fR as defined in RFC 3315 for
101 102 DHCPv6. The \fB/etc/dhcp/inittab\fR file contains only Sun vendor options.
102 103 Define non-Sun vendor options in the \fBdhcptab\fR file.

128 129 Data entries are written one per line and have seven fields; each entry
129 130 provides information for one option. Each field is separated by a comma, except
130 131 for the first and second, which are separated by whitespace (as defined in
131 132 \fBisspace\fR(3C)). An entry cannot be continued onto another line. Blank lines

140 141 Mnemonic Identifier

142 143 The Mnemonic Identifier is a user-friendly alias for the option number; it is
143 144 not case sensitive. This field must be per-category unique and should be unique
144 145 across all categories. The option names in the \fBSTANDARD\fR, \fBSITE\fR, and
145 146 \fBVENDOR\fR spaces should not overlap, or the behavior will be undefined. See

165 166 The Option Number is the number of this option when it is in a \fBDHCP\fR
166 167 packet. This field should be per-category unique and the \fBSTANDARD\fR and

542 544 .LP
543 545 In general, the \fBDHCP\fR \fBinittab\fR file should only be altered to add
544 546 \fBSITE\fR options. If other options are added, they will not be automatically
545 547 carried forward when the system is upgraded. For instance:

556 558 describes an option named \fBipPairs\fR, that is in the \fBSITE\fR category.
557 559 That is, it is defined by each individual site, and is option code 132, which
558 560 is of type \fBIP\fR Address, consisting of a potentially infinite number of
