In this area, you can set up additional attributes for IGEL OS devices using the IGEL Universal Management Suite (UMS). These attributes are displayed together with the default device attributes, see (12.04-en) View Device Information in the IGEL UMS. They can also be used in:

Known Limitations

Device attributes can only be managed within the UMS; there is no export or import facility.


Menu path: UMS Administration > Global Configuration > Device Attributes


Click on to set up a new device attribute:

Global Overwrite Rule

This parameter is relevant for devices with IGEL OS 11.07 or higher.

Defines the default overwrite rule for those device attributes whose overwrite rule is set to Global setting. The overwrite rule defines how the values of device attributes can be set and changed.

Possible options:

  • UMS/UMS Web App/IMI: Only the UMS can set and change the values of the device attributes. This is true regardless of which interface is used for UMS control, i.e. UMS Console, UMS Web App, or IGEL Management Interface (IMI).
  • Devices: Only the devices can set and change the values of the device attributes. See also (12.04-en) Managing IGEL OS Devices by Device Specific Data - What Device Attributes Can Do for You.
  • All: Both the UMS and the devices can set and change the values of the device attributes. New values overwrite older values.

Name

Display name of the attribute

UMS internal identifier

This identifier is required for creating/editing views or editing searches in text mode (see How to Create a New View in the IGEL UMS) and also for enabling the devices to set and change attribute values. If you do not plan to use any of these features, you can leave this field empty. 
You can either generate the internal identifier automatically by clicking Generate ID or specify it manually.

The UMS internal identifier must start with a lower-case letter. Only the following characters are allowed: a-z, A-Z, 0-9.

Type

Data type of the attribute

Possible values:

  • String: A sequence of letters, numbers, and special characters is expected.
  • List: A list of values is provided for selection. These values are specified as shown below:
    Values for the Attribute Type "List"
    - Value: Name of the predefined value
    - Description: Optional description of the value
  • Number: A numerical value is expected.
  • Date: A date is expected.

Description

Optional description of the attribute

Using the up and down arrows, you can change the order of the additional attributes.

In the device System Information, you can set the values for the attributes.

Overwrite Rule

This parameter is relevant for devices with IGEL OS 11.07 or higher.

Defines how the value of this device attribute can be set and changed.

  • Global setting: The Global Overwrite Rule is valid for this device attribute.
  • UMS/UMS Web App/IMI: Only the UMS can set and change the value of this device attribute. This is true regardless of which interface is used for UMS control, i.e. UMS Console, UMS Web App, or IGEL Management Interface (IMI).
  • Devices: Only the device can set and change the values of this device attribute. See also (12.04-en) Managing IGEL OS Devices by Device Specific Data - What Device Attributes Can Do for You.
  • All: Both the UMS and the devices can set and change the values of this device attribute. New values overwrite older values.
