Universal Network Terminal TAU-32M.IP
APPENDIX G. AUTOMATIC CONFIGURATION PROCEDURE AND GATEWEY FIRMWARE
VERSION CHECK
1.
Configuration parameters usage
'Enable autoupdate'
is an option that allows to use automatic software and configuration updates, and
perform their version checks in the defined periods of time.
TAU-32M.IP automatic configuration and configuration file version check operation algorithm.
For each TAU-32.IP, a reference configuration file is created; in /etc/config/cfg.yaml configuration file, specify
its current version #ConfigFileVersion=YYYYMMDDHHMM:
#!version 1.0
#TAU-32 YAML config file
#Tree hierarchy:
#node1:
# node2:
# param1: value1
# param2: value2
#NOTE: use spaces ' ' instead of tab '/t'
#NOTE: Don't del/add nodes
#NOTE: Use ':' after param names
#Remember, that quantity of spaces must be multiply to 8
#ConfigFileVersion=201302010905

During TAU-32M.IP startup, the gateway checks for the configuration file at the specified path on
FTP/TFTP/HTTP/HTTPS server (and signs in to server, if necessary). If the configuration file is present, TAU will
download it, store it in its file system and apply it as a current configuration file. Upon the expiry of
'Configuration
update interval'
timeout or when
'Configuration update time'
is coming, the gateway will re-download the
configuration file from the server and compare versions of the current and downloaded configuration files
(ConfigFileVersion). If the downloaded file version is higher that the current one, TAU-32M.IP saves and applies a
new configuration; otherwise, the current configuration remains active.
When the operator wants to modify the gateway configuration, he should upload the modified configuration
file with increased 'ConfigFileVersion' value to the server, and the configuration will be updated automatically upon
the expiry of
'Configuration update interval'
timeout or when '
Configuration update time
' is coming
.
After restart,
TAU-32M.IP will download configuration file from the server; this measure will protect the gateway from improper
configuration. If you experience problems after configuring the gateway via Web configurator, restart the device to
download the reference configuration.
