APPENDIX G. AUTOMATIC CONFIGURATION PROCEDURE AND GATEWAY FIRMWARE VERSION CHECK
'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 automatic configuration and configuration file version check operation algorithm
For each TAU, a reference configuration file is created; in
/etc/config/cfg.yaml
configuration file, specify
its current version #ConfigFileVersion=YYYYMMDDHHMM:
#!version 1.0
#tau-72 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
Network:
network:
HOSTNAME: tau72
During TAU 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, 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 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. After restart, TAU 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.
