User Guidelines
DHCP provides a framework for passing configuration information to hosts on a
TCP/IP network. Configuration parameters and other control information are
carried in tagged data items that are stored in the DHCP message options field.
The data items themselves are also called options. The current set of DHCP
options are documented in RFC 2131,
For options in hexadecimal format, the string parameter should include all the
bytes in the option value, including leading zeros.
Examples

Example 2 - The following example configures DHCP option 2, which specifies the
offset of the client's subnet in seconds from Coordinated Universal Time (UTC). A
value of 0xE10 in the following example indicates a location 1 hour east of the
