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.
