The following table describes some of the commands that you may see in third party FTP
clients.
24.2.2 Backup Configuration Using TFTP
The ZyXEL Device supports the up/downloading of the firmware and the configuration file
using TFTP (Trivial File Transfer Protocol) over LAN. Although TFTP should work over
WAN as well, it is not recommended.
To use TFTP, your computer must have both telnet and TFTP clients. To backup the
configuration file, follow the procedure shown next:
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 command “sys stdio 0” to disable the SMT timeout, so the TFTP transfer will not
be interrupted. Enter command “sys stdio 5” to restore the five-minute SMT 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.
