6.4.1.3.5 Table of Parameter Value Constraints
The ini file allows you to add/modify parameters in tables. When using tables, Read-Only
parameters are not uploaded, since the Read-Only parameters cause an error when trying
to download the uploaded file. Therefore read-only parameters should not be included in
tables in the ini file. Consequently, tables are uploaded with all parameters having at least
one of the following permissions:
Write
Create
Maintenance write
The 'format-line' rule defines which fields of the table are to be modified by the given ini file
(this may vary among ini files for the same table). The 'format-line' must only include fields,
which can be modified (which are all parameters that are not specified as read-only).
One exception is the index-fields, which are ALWAYS mandatory fields. In the "Table of
Parameter Values Example - Remote Management Connections" above, all fields except
the 'Time Connected' field are uploaded.
The lists of table parameters are provided in the Appendix, 'Table Parameters' on page
281.
6.4.1.4 Secured Configuration File Download
The ini file contains sensitive information required for appropriate functioning of the MG
3200. The ini file is uploaded to the MG 3200 or downloaded from the gateway using TFTP
or HTTP protocols. These protocols are unsecured (and thus vulnerable to a potential
hacker). Conversely, if the ini file is encoded, the ini file would be significantly less
vulnerable to outside harm.
6.4.1.4.1 Encoding Mechanism
The ini file to be loaded and retrieved is available with or without encoding. When an
encoded ini file is downloaded to the MG 3200, it is retrieved as encoded from the MG
3200 as well. When a decoded file is downloaded to the MG 3200, it is retrieved as
decoded from the MG 3200 as well.
In order to create an encoded ini file, the user must first create an ini file and then apply the
DConvert utility to it in order to encode it. (Refer to the Appendix, ''Utilities'' on page
for detailed instruction on ini file encoding.)
In order to decode an encoded ini file retrieved from the MG 3200, the user must retrieve
an encoded ini file from the MG 3200 using the Web server (refer to "Downloading Auxiliary
Files" below) and then use the DConvert utility in order to decode it. (Refer to the '
Appendix, '' Utilities' on page
Downloading the ini file with or without encoding may be performed by utilizing either TFTP
or HTTP.
