updated only once. To update a previously-loaded auxiliary file, you must update the
parameter containing its URL.
To load different configurations (ini files) for specific gateways, add the string <MAC> to
the URL. This mnemonic is replaced with the V7111 hardware MAC address. Resulting
in an ini file name request that contains the gateways MAC address.
To automatically update the cmp file, use the parameter CmpFileURL to specify its name
and location. As a precaution (to protect the V7111 gateway from an accidental update)
the Automatic Update mechanism does not apply to the cmp file by default. Therefore,
(to enable it) set the parameter AutoUpdateCmpFile to 1.
The following example illustrates how to utilize Automatic Updates for deploying devices with
minimum manual configuration.
To utilize Automatic Updates for deploying the V7111 gateway with minimum manual
configuration:
Set up a Web server (in the following example it is http://www.corp.com/) where all
1
configuration files are to be stored.
To each device, pre-configure the following parameter (DHCP / DNS are assumed):
2
IniFileURL = 'http://www.corp.com/master_configuration.ini'
Create a file named master_configuration.ini, with the following text:
3
# Common configuration for all devices
# ------------------------------------
CptFileURL = 'http://www.corp.com/call_progress.dat'
# Check for updates every 60 minutes
AutoUpdateFrequency = 60
# Additional configuration per device
# -----------------------------------
# Each device loads a file named after its MAC address,
# (for example, config_00908F033512.ini)
IniFileURL = 'http://www.corp.com/config_<MAC>.ini'
# Reset the device after configuration is updated.
# The device resets after all of the files are processed.
ResetNow = 1
You can modify the master_configuration.ini file (or any of the config_<MAC>.ini files) at any
time. The V7111 gateway queries for the latest version every 60 minutes and applies the
new settings immediately.
For additional security, use HTTPS or FTPS. The V7111 gateway supports HTTPS (RFC
1
2818) and FTPS using the AUTH TLS method <draft-murray-auth-ftp-ssl-16> for the
Automatic Update mechanism.
To load configuration files from an NFS server, the NFS file system parameters should
2
be defined in the configuration ini file. The following is an example of an ini file for loading
files from NFS servers using NFS version 2.
# Define NFS servers for Automatic Update
[ NFSServers ]
FORMAT NFSServers_Index = NFSServers_HostOrIP, NFSServers_RootPath,
NFSServers_NfsVersion;
NFSServers 1 = 10.31.2.10, /usr/share, 2 ;
