Troubleshooting guide: Uploading a configuration backup created with LANconfig 10.80 Rel results in incorrect configuration

Description:

When a configuration backup of a device with LCOS 10.80 Rel is created with LANconfig 10.80 Rel (automatically as well as manually), the markers for start and ending aren't set, if no Encryption password was added in LANconfig (under Options → Backup → Backup options). If such a configuration backup is uploaded to a device, only isolated parts of the configuration are transmitted. As a result, the configuration is no longer functional.

This article describes how the markers for start and end of the configuration backup can be added, so that the configuration backups are functional again.

Procedure:

There are two possibilities to add the markers.

1) Adding the markers by making a configuration change in the faulty configuration backup:

1.1) Doubleclick the affected configuration backup to open it in LANconfig. The default path for the automatic file backup in LANconfig is as follows:

C:\Users\<Username>\AppData\Roaming\LANCOM\LANconfig\Config\

1.2) Make any configuration change (e.g. in the Comments).

1.3) Finally, click OK, to save the configuration with the changes. The markers are added automatically.

2) Adding the markers manually via a text editor:

2.1) Open the configuration file in a text editor. The default path for the automatic file backup in LANconfig is as follows:

C:\Users\<Username>\AppData\Roaming\LANCOM\LANconfig\Config\

2.2) Add the marker for the start:

Enter the following text directly before the beginning of the configuration (SNMP path 1.2.1).

[TYPE: LCF; VERSION: 1.00; HASHTYPE: none;]

2.3) Add the marker for the end: 

Enter the following text at the very end of the file.

[END: LCF;]

2.4 Save the file in the text editor.
