1216BConfiguring self-defined DHCP options
CAUTION:
Be careful when configuring self-defined DHCP options because such configuration may affect DHCP
operation.
By configuring self-defined DHCP options, you can
• Define new DHCP options. New configuration options come out with DHCP development. To
support these new options, you can add them into the attribute list of the DHCP server.
• Define existing DHCP options. Vendors use Option 43 to define options that have no unified
definitions in RFC 2132. The self-defined DHCP option enables DHCP clients to obtain
vendor-specific information.
• Extend existing DHCP options. When the current DHCP options cannot meet the customers'
requirements (for example, you cannot use the dns-list command to configure more than eight DNS
server addresses), you can configure a self-defined option for extension.
To configure a self-defined DHCP option in a DHCP address pool:
