Using a Trivial File Transfer Protocol Server
The Trivial File Transfer Protocol (TFTP) enables you to transfer files to and from
your modem. Your system runs a
tftp
daemon that enables remote users who have
TFTP client software, to transfer files to and from the system. The TFTP client is
enabled and disabled from the CBOS or the Web Management Interface.
Caution
For security reasons, Cisco recommends that you disable the TFTP
application, except when uploading or downloading a file.
Software Updates
Use the TFTP utility to transfer a new software image from Cisco to your system,
where the filename equals nsrouter.c627.
x
.ima, where
x
is the release number.
Versions of CBOS 2.3 or higher use the filename format c627.
x
.bin, where
x
is the
release number.
Archives
Use the TFTP utility to back up a copy of your configuration file before changing
it,
so you can easily recover the old file if necessary. The naming conventions for the
configuration file are:
•
When using the
put
option of the
tftp
command, you must name the file
nscfg.cfg.
•
When using the
get
option of the
tftp
command, name the file any name that
a standard text editor can view and edit.
Using TFTP from a UNIX Machine
For information on the UNIX TFTP client, access the online manual on your
UNIX system. At the command-line prompt, enter:
man tftp
