■ [1] = Enable CRC for the entire file, including line order
(i.e., same text must be on the same lines). If there are
differences between the files, the device installs the
downloaded file. If there are no differences, the device
discards the newly downloaded file.
■ [2] = Enable CRC for individual lines only. Same as option
[1], except that the CRC ignores the order of lines (i.e.,
same text can be on different lines).
Defines the size of the TFTP data blocks (packets) when
downloading a file from a TFTP server for the Automatic
Update mechanism. This is in accordance to RFC 2348.
TFTP block size is the physical packet size (in bytes) that a
network can transmit. When configured to a value higher than
the default (512 bytes), but lower than the client network's
Maximum Transmission Unit (MTU), the file download speed
can be significantly increased.
The valid value is 512 to 8192. The default is 512.
Note:
■ A higher value does not necessarily mean better
performance.
■ The block size should be small enough to avoid IP
fragmentation in the client network (i.e., below MTU).
■ This feature is applicable only to TFTP servers that
support this option.
Invokes an immediate device reset. This option can be used
to activate offline (i.e., not on-the-fly) parameters that are
loaded using the parameter IniFileUrl.
■ [0] = (Default) The immediate restart mechanism is
disabled.
■ [1] = The device immediately resets after an ini file with
the parameter set to 1 is loaded.
Note: If you use the parameter in an ini file for periodic
automatic provisioning with non-HTTP (e.g., TFTP) and
without CRC, the device resets upon every file download.
Defines the name of the cmp file and the URL address (IP
address or FQDN) of the server where the file is located.
Optionally, the username and password (username:password)
for access authentication with the server can also be
configured. For example:
'http://192.168.0.1/filename'
'https://<username>:<password>@<IP address>/<file
name>'
