9145 Network Interface Device 3-13
CfgFileUserComments is a string of 50 characters that the user may set to any string
desired. This variable contains information relevant to the user.
An example of the header as it would appear on a 9145_001.cfg file is shown here:

The configuration file consists of the header followed by a list of keywords. Each keyword
represents a user defined variable that is be set in the file.
The configuration file functions is both backward and foreword compatible. A configuration file
built with a newer firmware version may contain keywords that an older firmware version may
not recognize. In this case, the 9145 simply skips over the keyword and doesn’t act on it.
Similarly, a configuration file built with an older firmware may not have all the keywords that a
newer firmware may expect to see. The 9145 ignores that expected keywords are missing.
In the case where the 9145 encounters a keyword that is not recognized, an error message is
generated and placed in the System Log and a Syslog message is sent. This helps the user to
spot errors in the configuration files.
Configuration files are uploaded and downloaded in-band using FTP and SFTP, in the same
manner that firmware and bootcode is uploaded and downloaded.
Note: TFTP is not supported.
Supported Configuration Parameters
The Configuration Backup and Restore function supports all configurable parameters for the
9145 with the exception of the following:
• The NPA parameters (including NPA profiles and address lists) ARE NOT supported.
Avoiding a Loss of Connectivity
Since configuration files contains Manager IP Address, Subnet Mask and Default Gateway
parameters, it is conceivable that a user may lose connectivity to a 9145 after downloading a
configuration file. A configuration file may contain values for the Manager parameters that are
different than the current Manager settings. To avoid such situations where management
connectivity to the 9145 could be lost, three additional “master control keywords” will follow the
configuration file header, as shown below:
