Automatic Update

The automatic update is used to provide devices in the field with updated firmware or configurations. The download list is on a central server and is checked by the devices if the action Start Auto-Update is triggered by an event.

Download list syntax

The download list is a text file (ASCII or UTF-8 without BOM) that refers to the update packet to be downloaded. A line consists of two fields that are separated by;.
The first field contains either the device-individual serial number or*as a wildcard for all devices.
The second field contains the absolute path to the update packet.
Lines beginning with#will be ignored.
Only the first fitting line will be evaluated on each device.
Example:

16334455;/configs/profile.tar  
*;/updates/autoupdate-2.0-to-2.3.tar 

Sequence

In order to avoid the transmission of unnecessary data, the fields Content-MD5, ETag and Last-Modified can be evaluated from the HTTP or FTP header of the auto update server. In case of FTP, only Last-Modified will be evaluated. The Precondition for download option allows following behaviour:

If the auto-update server does not support the header fields, the download list will always be downloaded and the file name of the update packet can be checked.
If the update packet will then be downloaded successfully, it will be stored (regardless of whether it has been modified) and the individual entries will be applied in the order listed in the manifest. The FILETYPE ASCII Configuration will be executed immediately and not stored. In case of firmware auto-update packets, the contained ASCII Configuration will check the running firmware version and only activate the stored firmware if it is more recent than the running firmware.
The auto-update cache that stores the information for comparing the versions can be deleted when resetting the router to default settings.
