Automatic Update Mechanism - 3Com VCX v7111 User Manual

Automatic Update Mechanism

The V7111 gateway is capable of automatically updating its cmp, ini and configuration files.
These files can be stored on any standard Web, FTP or NFS server/s and can be loaded
periodically to the gateway using HTTP, HTTPS, FTP, or NFS. This mechanism can be used
even for Customer Premise(s) Equipment (CPE) devices that are installed behind NAT and
firewalls.
The Automatic Update mechanism is applied separately to each file. For the detailed list of
available files and their corresponding parameters, see
The Automatic Update mechanism assumes the external Web server conforms to the
HTTP standard. If the Web server ignores the If-Modified-Since header, or does not
provide the current date and time during the HTTP 200 OK response, the gateway
may reset itself repeatedly. To overcome this problem, adjust the update frequency
(AutoUpdateFrequency).
Three methods are used to activate the Automatic Update mechanism:
After the V7111 gateway starts-up (see the Startup process described in
At a configurable time of the day (for example, 18:00). This option is disabled by default.
At fixed intervals (for example, every 60 minutes). This option is disabled by default.
The following ini file example can be used to activate the Automatic Update mechanism.
Figure 111 Example of an ini File Activating the Automatic Update Mechanism
# DNS is required for specifying domain names in URLs
DnsPriServerIP = 10.1.1.11
# Load an extra configuration ini file using HTTP
IniFileURL = 'http://webserver.corp.com/3Com/inifile.ini'
# Load Call Progress Tones file using HTTPS
CptFileUrl = 'https://10.31.2.17/usa_tones.dat'
# Load Voice Prompts file using FTPS with user root and password wheel
VPFileUrl = 'ftps://root:wheel@ftpserver.corp.com/vp.dat'
# Update every day at 03:00 AM
AutoUpdatePredefinedTime = '03:00'
# Note: The cmp file is not updated since it is disabled by default
(AutoUpdateCmpFile).
See the following notes:
When HTTP or HTTPS are used, the gateway contacts the Web server/s and queries for
the requested files. The ini file is loaded only if it was modified since the last automatic
update. The cmp file is loaded only if its version is different from the version stored on
the gateways non-volatile memory. All other auxiliary files (for example, CPT) are
