DHCP Server Options Feature

The Dell SonicWALL DHCP server options feature provides support for DHCP options, also known as vendor extensions, as defined primarily in RFCs 2131 and 2132. DHCP options allow users to specify additional DHCP parameters in the form of predefined, vendor-specific information that is stored in the options field of a DHCP message. When the DHCP message is sent to clients on the network, it provides vendor-specific configuration and service information. The section DHCP Option Numbers provides a list of DHCP options by RFC-assigned option number.

Benefits

The Dell SonicWALL DHCP server options feature provides a simple interface for selecting DHCP options by number or name, making the DHCP configuration process quick, easy, and compliant with RFC-defined DHCP standards.

How the DHCP Server Options Feature Works

The DHCP server options feature allows definition of DHCP options using a drop-down menu based on RFC-defined option numbers, allowing administrators to easily create DHCP objects and object groups, and configure DHCP generic options for dynamic and static DHCP lease scopes. Once defined, the DHCP option is included in the options field of the DHCP message, which is then passed to DHCP clients on the network, describing the network configuration and service(s) available.

Supported Standards

The DHCP server options feature supports the following standards:

•	RFC 2131 - Dynamic Host Configuration Protocol

•	RFC 2132 - DHCP Options and BOOTP Vendor Extensions
