Configuration Management
Configuration management allows you to save all or parts of your
configuration. The Digi CM saves all configurations when the
Save & apply
button is used or the Apply changes link is used. These configurations are
saved to the local CM in /tmp/cnf directory by default. Manage these
configurations by exporting the files to your location of choice.
1. Click System administration > Configuration management. The
Configuration management screen appears.
2. Under Configuration Export, select the file locations that you wish to save
enter a name and click Export .
Automatically Upgrading the Digi CM Firmware or Configuration using TFTP
The Digi CM supports upgrading the firmware, configuration, or any other files
in the file system using a TFTP-based mechanism.
During boot, the Digi CM can verify a “hash” file and determine if it needs to
download upgrades from the TFTP server.
There are multiple ways to configure the TFTP upgrade function.
DHCP
The DHCP server can automatically assign a TFTP upgrade server and file to
the Digi CM during boot. The options implemented are:
(66) TFTP server address
(67) TFTP filename (this is the filename of the hash file)
To enable DHCP firmware upgrade:
1. Click System administration > Firmware upgrade.
2. Set “Automatic firmware and configuration upgrade at boot time” to Enable.
3. Set “Use DHCP option for remote server and hash file” to Yes.
4. Click Save & apply .
The next time the Digi CM reboots, it will analyze the hash file and upgrade the
firmware, configuration, or other files if required.
