		 |  |  |   Create OptionThe Create Option dialog box lets you create new option definitions in the
dhcptab on the selected DHCP server.
See 
About Macros and Options, for more information about defining DHCP options. 
The settings in the Create Option dialog box are described in the following table.
 
 
	 
	
	| Name | The name of the option.
	Option names can be a maximum of 128 alphanumeric characters including spaces. |  
	| Category | The category of the option: 
	The category can be one of Site, Extend, or Vendor. 
	 
		
		
		| Site | User-defined option definitions, used for 
		unique or custom purposes; accepts Option 
		Codes 128-254. |  
		| Extend | Option definitions beyond the standard set, 
		which may already be present in versions of the DHCP protocol 
		being used on your server. Rather than upgrading your DHCP 
		implementation, you can add extended options; accepts Option 
		Codes 77-127. |  
		| Vendor | Hardware-, vendor-, or platform-specific option 
		definitions; accepts Option Codes 1-254. Selecting this 
		context enables the Client Class 
		parameter. |  |  
	| Code | A unique numeric code to 
	identify the option. Valid values depend on the option category: 
	 
		
		| Extend | Accepts code values of 77-127 |  
		| Site | Accepts code values of 128-254 |  
		| Vendor | Accepts code values of 1-254 |  
 |  
	| Data Type | The type of data that is acceptable 
	for options values: 
		 
		
		| Ascii | ASCII text. |  
		| Boolean | No value is associated with this data type. 
		Presence of options of this type denote Boolean TRUE; absence 
		denotes FALSE. |  
		| IP | One or more Internet addresses in dotted decimal format. |  
		| Octet | Uninterpreted ASCII representation of binary 
		data; for example, a client ID. |  
		| Unumber8 Unumber16
 Unumber32
 Unumber64
 
 | Unsigned number, where the trailing number indicates the number of bits in the number. |  
		| Snumber8 Snumber16
 Snumber32
 Snumber64
 
 | Signed number, where the trailing number indicates the number of bits in the number. |  |  
	| Granularity | Specifies how many values of the given data type are required to make a complete option value. 
	For example, a data type of IP and a granularity of 2 would 
	mean that the option value would need to contain two IP addresses. |  
	| Maximum | The maximum number of values of a 
	given granularity that can be specified for the option. Building on the 
	previous example, a maximum of 2, with a granularity of 
	2 and a data type of IP would mean that the option 
	value could contain a maximum of two pairs of IP addresses. 
		 
		
		| Unlimited | No limit to the number of values; implies a 
		maximum setting of 0. |  
		| Specify | A specific number indicating the maximum. |  |  
	| Vendor Client Classes | This option is enabled only when the option 
	category is Vendor. It identifies the client class(es) with which the Vendor option is
	associated. 
	The Class is an ASCII string representing the client machine type and/or operating system, for example, SUNW.Ultra5_10. This type of option makes it possible to define configuration parameters that are passed to all clients of the same class.  
	Enter the client class and then press Enter. You can
	specify multiple client classes. Only those DHCP clients with a client 
	class value matching one listed here will use the option. |  
	
Notify DHCP Server of Change: Check the box if 
you want the DHCP server to reload the dhcptab immediately after
the data is written. Normally, you will want this to
happen. However, if you are making multiple changes, you may choose
to wait so that the server reloads only after all the
changes are written.
