Automatically Upgrade Firmware or Configuration using TFTP
The Digi Passport unit supports upgrading the firmware, configuration, or
any other files in the file system using a TFTP-based mechanism. When
booting, the Digi Passport unit can verify a “hash” file and determine if it
needs to download upgrades from the TFTP server. The TFTP upgrade
function can be configured using DHCP or by directly configuring the TFTP
server and the name of the hash file.
Using DHCP
The DHCP server can automatically assign a TFTP upgrade server and file
to the Digi Passport unit during boot. The options implemented are:
• (66) TFTP server address
• (67) TFTP filename (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 Passport unit reboots, it will analyze the hash file
and upgrade the firmware, configuration, or other files if required.
Directly Configure the TFTP Server and the Name of the hash File
To configure the IP address of the TFTP server and the filename of the
hash file on the Digi Passport unit, follow the steps below:
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 No.
4. Configure the IP address of remote server.
5. Configure the Hash file name.
6. Click Save & apply.
The next time the Digi Passport unit reboots, it will analyze the hash file
and upgrade the firmware, configuration, or other files if required.
If any problems occur during the TFTP upgrade process, verify that the
hash file and the other files are accessible using TFTP.
