The following table describes some of the commands that you may see in third party FTP

clients.

18.2.3 Backup Configuration Using TFTP

The G-1000 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 G-1000 and log in. Because TFTP does

not have any security checks, the G-1000 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.
