CHAPTER72 Configuration Parameters Reference
Mediant 800 Gateway & E-SBC | User's Manual
Parameter Description
The valid value is a string of up to 128 characters. The syntax
is 'username:password' (e.g., 'joe:1234'). By default, no value
is defined.
Note: The device only uses the username and password
configured by this parameter if no username and password
has been configured for the parameter used to configure the
URL of the server with the name of the file, for example,
[CmpFileURL].
crc-check regular
[AUPDCheckIfIniChanged]
Enables the device to perform cyclic redundancy checks
(CRC) on downloaded configuration files during the Automatic
Update process. The CRC checks whether the content (raw
data) of the downloaded file is different to the content of the
previously downloaded file from the previous Automatic
Update process. The device compares the CRC check value
(code) result with the check value of the previously
downloaded file. If the check values are identical, it indicates
that the file has no new configuration settings, and the device
discards the file. If the check values are different, the device
installs the downloaded file and applies the new configuration
settings.
■ [0] = (Default) Disable - the device does not perform CRC
and installs the downloaded file regardless.
■ [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).
tftp-block-size
[AUPDTftpBlockSize]
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.
