system nvData save Stores nonvolatile (NV) da ta 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 th e system
fileTransfer option. The S uperStack 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 fi le 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 th e default TFTP directory. Consult your
network administrator or TFTP documentation for details about yo ur
host system’s TFTP implementation.
■Because TFTP provides no user authentication, give loose permissions
to the control file an d the NV data file on the remote host (that i s,
make the files publicly readable and writable). TFTP servers do not
grant requests for file access.
