Digi CM User Guide 142
Syntax for action 2: configuration upgrade
<image name>,<model name>,<version>
<image name>
specifying the path and the filename of the configuration file on the TFTP server
<model name> specifying the product name especially the port count e.g. DigiCM48, DigiCM32,
DigiCM16 or DigiCM8
This allows you to have one hash file for different models.
<version> the version number of the firmware
The Digi CM unit will download the configuration if the version in the hash file is different from the
version saved in the file /tmp/cnf/.cnfversion. This file does not exist until you do the first automatic
configuration upgrade. It is also deleted if the unit is reset to factory defaults.
If the /tmp/cnf/.cnfversion file does not exist, no download will occur. The file /tmp/cnf/.cnfversion
is a hidden file.
Example:
config.tar.gz,DigiPassport48,v1.6.0
After the firmware configuration is upgraded the Digi CM unit boots again.
A sample hash file can be downloaded from:
