If a device configuration is stored manually, LANconfig provides the option to save extra meta data in addition to the usual MAC address and/or device serial number in the configuration file (*.lcf). This extended meta-data can be taken into account, for example when performing a quick config rollback or when loading a device configuration via USB.
To include the additional meta data into a configuration file, click the Advanced button in the LANconfig save-file dialog and enter the data—if not entered already—into the respective fields.
Alternatively you can open a lcf/lcs file in a text editor and enter the advanced meta data by hand. Add to the line (<Firmware>) (<Feature-Mask>;<Feature-IDs>;<Hardware-Mask>) the following text with the brackets (MAC:<MAC-Address>;SERIAL:<Serialnumber>).
Example:
(Configuration of 'DEVICE-01' from 8/12/2014) (9.00.0212) (0x0000c010,IDs:4,e,f,2b;0x0c000002) (MAC:00a0571d12fc;SERIAL:4002578718100036)
