CANOGA PERKINS N525 Ethernet Termination Service Unit - Manual (Page 32)

3-14 N525 Ethernet Termination Service Unit
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 N525 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 N525 ignores that expected keywords are missing.
In the case where the N525 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
N525 with the exception of NPA parameters. 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 N525 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 N525 could be lost, three additional “master control keywords” will follow the
configuration file header, as shown below:
############################################
## The following must be modified to = "Yes" if the specified items
## are to be configured, otherwise the config items will be ignored.
ConfigureIPAddress = No
ConfigureSBMC = No
ConfigureInterface = No
