Firmware and Configuration File Maintenance 21-11
Note that the telnet connection must be active and the VES in CI mode before and during the TFTP transfer. For
details on TFTP commands (see following example), please consult the documentation of your TFTP client
program. For UNIX, use “get” to transfer from the VES to the computer, “put” the other way around, and “binary”
to set binary transfer mode.
21.4.6 TFTP Upload Command Example
The following is an example TFTP command:
tftp [-i] host put firmware.bin ras
where “i” specifies binary image transfer mode (use this mode when transferring binary files), “host” is the VES’s
IP address, “put” transfers the file source on the computer (firmware.bin – name of the firmware on the computer)
to the file destination on the remote host (ras — name of the firmware on the VES).
Commands that you may see in GUI-based TFTP clients are listed earlier in this chapter.
21.4.7 Uploading Via Console Port
FTP or TFTP are the preferred methods for uploading firmware to your VES. However, in the event of your
network being down, uploading files is only possible with a direct connection to your VES via the console port.
Uploading files via the console port under normal conditions is not recommended since FTP or TFTP is faster.
Any serial communications program should work fine; however, you must use the Xmodem protocol to perform
the download/upload.
