Instead of adding devices one by one, you can add subnets to Device Groups to assume every device using this subnet as a member of this Device Group.


To add a subnet to a Device Group:

1. Log in to the **Single Connect Web GUI**.
2. Navigate to **Device Management** > **Device Groups**.
3. Right-click the device group to be discovered and select **Add/Edit Subne**t.
