5 – server address code; server address URL should be specified in the following format: tftp://address
or
http://address
. The first version represents TFTP server address, the second version – HTTP server
address;
6 – configuration file name code;
7 – firmware file name code;
"|" – mandatory separator used between codes and suboption values.
Algorithm of identification for configuration file and firmware file URL parameters from DHCP Options 43
and 66.
1.
DHCP exchange initialization
Device initializes DHCP exchange after the startup.
2. Option 43 analysis
When Option 43 is received, codes 5, 6, and 7 suboptions are analyzed in order to identify the server
address and the configuration and firmware file names.
3. Option 66 analysis
If Option 43 is not received from DHCP server or it is received but the system fails to extract the server
address, Option 66 will be discovered. If the system fails to obtain the firmware file name, Option 67 will
be discovered. They are used for TFTP server address and the firmware file path extraction respectively.
Next, configuration and firmware files will be downloaded from Option 66 address via TFTP.
Special aspects of configuration updates
Configuration file should be in
.tar.gz
format (this format is used when configuration is saved from the web
interface in the «System» – «Configuration management» tab). Configuration downloaded from the server will
be applied automatically and does not require device reboot.
Special aspects of firmware updates
Firmware file should be in
.tar.gz
format. When the firmware file is loaded, the device unpacks it and checks its
version (using 'version' file in
tar.gz
archive).
If the current firmware version matches the version of the file obtained via DHCP, firmware will not be updated.
Update is performed only when firmware versions are mismatched. When the firmware image is written into
the device flash memory, the Power indicator will flash green, orange and red in succession.
For autoconfiguration via TR-069, suboptions 1, 3 and 4 will be applied when in the autoconfiguration
section the priority is selected from DHCP options on the basis of DHCP.
Do not power off or reboot the device, when the firmware image is written into the flash memory. These
actions will interrupt the firmware update that will lead to the device boot partition corruption. The
device will become inoperable. To restore the device operation, use the instruction provided in
System
recovery after firmware update failure
