About DHCP Templates

A template contains a set of predefined properties that you use to create IPv4 and IPv6 DHCP objects. It is metadata that you can modify and reuse. Using a template enables you to create objects in a quick and consistent way. You can define the object properties once in a template, and then create multiple objects that inherit their properties from the template. For example, you can create a network template that has a fixed netmask of /24 and extensible attribute "State" set to California. You can then use the template to create networks in California that contain /24 netmasks.
You can also modify and delete a template. Note that modifying or deleting a template does not affect existing objects created based on the template. You must be a superuser or have read/write permissions to add, modify, or delete a template. A superuser can set other admin group privileges on templates. For information, see Administrative Permissions for IPv4 or IPv6 DHCP Templates. You can also define extensible attributes for these templates when you create them. For information, see Using Extensible Attributes.
