The following mechanism ensures that IGEL OS is deployed only once to each device: After successful installation, the target device informs the appliance that IGEL OS is installed. Based on this information, the appliance adds the device's MAC address to the MAC address filter. You can find this MAC address under
Automatically added; see
Listing the MAC Address Filter. When a device's MAC address is in the MAC address filter, the device will not receive a DHCP address from the build-in DHCP server. The device will boot into IGEL OS without network.
