6 - configuration file name code;
7 - firmware file name code;
'|' - mandatory separation symbol between codes and suboption values.
For TR-069 autoconfiguration, suboptions 1, 3 and 4 will be used when the priority from the DHCP
options is selected in the 'Autoconfiguration based on the DHCP' section.
Algorithm for determining the parameters of the URL configuration files and software from the DHCP
options 43 and 66.
1.
DHCP sharing initialization
After loading, the device initiates a DHCP sharing.
2.
Option 43 analysis
When option 43 is received, suboptions with codes 5, 6, and 7 are analyzed to determine the server
address and the names of the configuration files and software.
3.
Option 66 analysis
If option 43 from the DHCP server was not received or received, but the server address could not be
retrieved from it, option 66 is searched. If the firmware file name also failed to get - option 67 search is
performed. The TFTP server address and the path to the firmware file are extracted from them, respectively.
Than the configuration and firmware files will be downloaded from the address from option 66 via TFTP.
Configuration update features.
The configuration file must be in the
.tar.gz
format (in this format, the configuration is saved via the
Web interface in the 'System' - 'Configuration Management' tab). The configuration downloaded from the
server is applied automatically without rebooting the device.
Firmware update features.
The firmware file must be in the .tar.gz format. After downloading the firmware file, it is unpacking
and checking the version (based on the contents of the version file in the tar.gz archive).
If the current firmware version matches the version of the file received via DHCP, the firmware will
not be updated. Updating is performed only in case of a version mismatch. The running process of recording
a firmware image to the flash memory of the device is indicated by the alternating cyclical blinking of the
'Power' indicator in green, orange and red.
Do not turn off the power or overload the device while writing the image to flash-memory. These
actions will lead to a partial recording of firmware, which is equivalent to damage to the boot
partition of the device. Further operation of the device will be impossible. To restore the device,
use the instructions provided in the section 6
