DHCP Server Configuration
Use this notebook tab to build a list of PXE (Preboot
eXecution Environment) client options. You can define:
- An option value for an option. To define an option value, click on
an option in the option list. Information about the option appears,
including a brief description of the option and its format requirements, which
vary depending on the option's data type.
- A new option format for the configuration. An option format is a
template for the type of value to be entered for an option. For
example, if the option format is IP address, an IP address specified in dotted
decimal notation, such as 9.67.3.77, must be
entered.
You cannot:
- Use an existing option number for a new option
- Edit an option already used in the configuration
- Modify or delete an architected option
Note:
The DHCP Server Configuration program has one set of option definitions per
DHCP server. Therefore, if you reformat an option, the new format is
applied to any configuration file subsequently opened with the DHCP Server
Configuration program for the server. User-defined PXE client option
formats are shared by the DHCP and BINL servers and server configuration
programs. PXE client options are stored as global PXEClient vendor
options for the DHCP Server Configuration program.
Fields and other information include:
- Available Options
- Lists the formatted PXE client options (options with defined formats),
including the architected options and any options for which you have defined
formats. Sort the options by option number, alphabetically, or by
used/unused options. An unused option is an option that has never been
specified for any item in the configuration.
For more information about options, see the online book DHCP Server
Administration.
- Option Value
- For a selected option, displays the option name, the level (scope) at
which the option is defined, and the option value. A value might
already exist at a global level, either for the server or for a group.
The display changes depending on the type of option.
- Option Description
- Displays the purpose of the option.
