V6100 and V7122 User Guide

You can modify the master_configuration.ini file (or any of the config_<MAC>.ini files) at any
time. The V7122 queries for the latest version every 60 minutes and applies the new settings
immediately.
For additional security, use HTTPS or FTPS. The gateway supports HTTPS (RFC 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
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 ;
NFSServers 2 = 192.168.100.7, /d/shared, 2 ;
[ \NFSServers ]
CptFileUrl = 'file://10.31.2.10/usr/share/public/usa_tones.dat'
VpFileUrl = 'file://192.168.100.7/d/shared/3Com/voiceprompt.dat'
Startup Process
The startup process (illustrated in
Figure 95
) begins when the gateway is reset (physically or
from the Web / SNMP) and ends when the operational software is running. In the startup
process, the network parameters, software and configuration files are obtained.
After the gateway powers up or after it is physically reset, it broadcasts a BootRequest
message to the network. If it receives a reply (from a BootP server), it changes its network
parameters (IP address, subnet mask and default gateway address) to the values provided.
If there is no reply from a BootP server and if DHCP is enabled (DHCPEnable = 1), the
gateway initiates a standard DHCP procedure to configure its network parameters.
After changing the network parameters, the gateway attempts to load the
cmp
and various
configuration files from the TFTP server’s IP address, received from the BootP/DHCP
servers. If a TFTP server’s IP address isn’t received, the gateway attempts to load the
software (
cmp
) file and / or configuration files from a preconfigured TFTP server (see
Automatic Update Mechanism
). Thus, the gateway can obtain its network parameters from
BootP or DHCP servers and its software and configuration files from a different TFTP server
(preconfigured in i
ni
file).
If BootP/DHCP servers are not found or when the gateway is reset from the Web / SNMP, it
retains its network parameters and attempts to load the software (
cmp
) file and / or
configuration files from a preconfigured TFTP server.
If a preconfigured TFTP server doesn’t exist, the gateway operates using the existing
software and configuration files loaded on its non-volatile memory.
