– optional –

Note:

DHCP options can only be applied to eLux devices.

A new device booting for the first time can retrieve the following information from a DHCP server:

IP address or name of the Scout Server (option 222)
List of Scout Servers (option 224)
ID of the destination OU on the Scout Server (option 223)

This requires configuring the DHCP server via one of the two following methods.

In method 1 (recommended), you define a new vendor class, set the new options, and then apply the values. Method 2 uses the DHCP Standard Options 222, 223 and 224.

The following instructions are based on the DHCP manager of Windows Server 2012.

Method 1: Defining user-defined vendor class

Requires
DHCP server compliant with RFC 2132, supporting user-defined vendor classes. Otherwise use method 2.

Open the DHCP manager.
Select the relevant DHCP server, and then click Action > Define

Click Add to create a new class:

Option	Value
Display name	eLux NG
Description	eLux specific options
Code	ELUXNG
(in ASCII column)	The entry is automatically extended with the related hexadecimal number (45 4C 55 58 4E 47).

Click Action > Set Predefined Options. Then, in the Option class list field, select eLux NG.

To define one Scout Server, click Add and edit the new option as follows:

Option	Value
Name	Scout Server
Data type	String
Code	222
Description	Name or IP address of the Scout Server

To define more than one Scout Server, click Add… and edit the new option as follows:

Option	Value
Name	Scout Server list
Data type	String
Code	224
Description	Server names/IP addresses, comma-separated

To define a specific OU that you can assign new devices to, click Add… and edit the new option as follows:

Option	Value
Name	Scout OU ID
Data type	Long
Code	223
Description	ID of the destination OU

To assign the options, for the relevant DHCP server, select either the Server Options, the Scope options or the Reservations. Then click Action > Configure Options… > Advanced.

In the Vendor class list field, select [elux NG]. Select each option defined and enter its value into the Data entry field:

Option	Value
222 Scout Server	Name or IP address of the Scout Server
223 Scout OU ID	ID of the destination OU
224 Scout Server list	<Names or IP addresses of the Scout Servers, separated by comma>

Method 2: Using DHCP Standard Options

Requires
The DHCP Standard Options [222], [223] and [224] must be available. Otherwise use Method 1.

Open the DHCP manager.
Select the relevant DHCP server, and then click Action > Set Predefined Options…. In the [Option class] list field, select [DHCP Standard Options].
Click Add… to create the following Standard Options, as described for Method 1:
- [Scout Server], String, 222
- Scout Ernteprise server list, String, 224
- [Scout] OU ID, Long, 223

To assign the options, for the relevant DHCP server, select either the Server Options, the Scope options or the Reservations. Then click Action > Configure Options… > General.

Select each option defined and enter its value into the Data entry field:

Option	Value
222 Scout Server
223 Scout OU ID	ID of the destination OU
224 Scout Server list	<Names or IP addresses of the Scout Servers, separated by comma>

Disabling DHCP option 12 as source for host names

If you have configured DHCP option 12 (host name), when connecting new devices, you can have the host names set via DHCP. To obtain the host name not via DHCP but from another source, such as the name template defined in the Scout Console, prevent the take-over from DHCP option 12. To do so, use a terminal.ini parameter:

File: /setup/terminal.ini
Section: [Network]
Entry: IgnoreDHCPHostname
Value: true (The default value is false.)
