system nvData save

Stores nonvolatile (NV) data on a server. The CoreBuilder 3500 uses the
Trivial File Transfer Protocol (TFTP) or File Transfer protocol (FTP) to transfer
the files to the host, depending on the setting for the

system

fileTransfer

option. The SuperStack II Switch 3900, Switch 9300, and

the CoreBuilder 9400 use TFTP to transfer files.

Important Considerations (TFTP)

To store NV data, you must first create two files on the TFTP server
before you send the data:

Control file — Use any filename that is meaningful to you.
Example:

ctrlfile

NV data file — Use the control filename plus the .nvd extension.
Example:

ctrlfile.nvd

When the system saves NV data, it writes it to a disk file on a host
computer (that is, a server) using TFTP or FTP. You can then retrieve the
data from the disk file with the

restore

option.

Some TFTP implementations require that you store the files in the
same directory in which the TFTP daemon (server) is running on the
remote host.

Some TFTP implementations require a full path, while other
implementations allow you to specify only the file name, and the
system saves the file to the default TFTP directory. Consult your
network administrator or TFTP documentation for details about your
host system’s TFTP implementation.

Because TFTP provides no user authentication, give loose permissions
to the control file and the NV data file on the remote host (that is,
make the files publicly readable and writable). TFTP servers do not
grant requests for file access.
