Tftp Upload Command Example; Uploading Via Console Port; Uploading Firmware File Via Console Port - ZyXEL Communications P-202H V2 User Manual

P-202H Plus v2 User's Guide
1 Use telnet from your computer to connect to the ZyXEL Device and log in. Because
TFTP does not have any security checks, the ZyXEL Device records the IP address of the
telnet client and accepts TFTP requests only from this address.
2 Put the SMT in command interpreter (CI) mode by entering 8 in Menu 24 – System
Maintenance.
3 Enter the command "sys stdio 0" to disable the console timeout, so the TFTP transfer will
not be interrupted. Enter "command sys stdio 5" to restore the five-minute console
timeout (default) when the file transfer is complete.
4 Launch the TFTP client on your computer and connect to the ZyXEL Device. Set the
transfer mode to binary before starting data transfer.
5 Use the TFTP client (see the example below) to transfer files between the ZyXEL Device
and the computer. The file name for the firmware is "ras".
Note that the telnet connection must be active and the ZyXEL Device 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 ZyXEL Device to the computer, "put" the other way around, and "binary" to set binary
transfer mode.

29.4.6 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 ZyXEL Device's IP address and "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 ZyXEL Device).
Commands that you may see in GUI-based TFTP clients are listed earlier in this chapter.

29.4.7 Uploading Via Console Port

FTP or TFTP are the preferred methods for uploading firmware to your ZyXEL Device.
However, in the event of your network being down, uploading files is only possible with a
direct connection to your ZyXEL Device 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.
