Device Groups
You can specify multiple device types in a security policy. As an alternative, you can add multiple device types to a custom device group and include the group in the policy. This enables you to create a different policy for devices that you know than for devices in general.
To create a custom device group and add devices to it
1. Go to User & Device > Device > Device Groups.
The list of device groups is displayed.
2. Select Create New.
3. Enter a Name for the new device group.
4. Click in the Members field and click a device type to add. Repeat to add other devices.
5. Select OK.
