Configuring a Self-Defined DHCP Option

By configuring self-defined DHCP options, you can:
Define new DHCP options. New configuration options will come out with DHCP development. To
support new options, you can add them into the attribute list of the DHCP server.
Extend existing DHCP options. When the current DHCP options cannot meet 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.
Follow these steps to customize the DHCP service:
