With the BloxOne With the Universal DDI application, you can configure DHCP properties at the global level. You can also configure properties to the DHCP configuration profile. Properties can also be assigned to IP space, DHCP hostNIOS-X Server, address block, subnet, address range, and fixed address levels. The DHCP properties follow a top-down inheritance hierarchy in which child objects automatically inherit DHCP properties from their parent objects. Thus, global DHCP properties remain at the top of the hierarchy and are inheritable to all child objects unless you override them at the object level.
For example, when you set DHCP properties for a particular DHCP server, these properties override the Global DHCP settings and apply to all objects served by that DHCP server. Properties set at the DHCP Server level override global settings and apply to the objects that reside beneath the DHCP server level. Properties set at the network level override object-level settings and apply to the objects within the network. Properties set for a DHCP range override those properties set at higher levels. For information about global DHCP properties, seeConfiguring Global DHCP Properties.
When a DHCP object contains inherited values from the parent objects, Cloud Services Infoblox Portal displays the corresponding information when you create or modify the object. Based on the information, you can decide whether to override or keep the inherited values. You must have read/write permissions to the DHCP resources to override inherited values. You can only view inherited values and paths if you have read-only permissions. For more information, see About DHCP Inheritance.
