Vendor-defined classes are used for managing DHCP options assigned to clients identified by vendor type.
User-defined classes are used for managing DHCP options assigned to clients identified by a common need for a similar DHCP options configuration.
After defining an option class, individual scopes must be configured with any class-related options to be provided to clients.

- Click Add.
- In the New Class dialog box, type a descriptive identifying name for the new option in the Display name box. You may also add additional information to the Description box.
