Configuring a Self-Defined DHCP Option 
By configuring self-defined DHCP options, you can: 
z  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. 
z  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 configure a self-defined DHCP option:
