18.2.3 Backup Configuration Using TFTP
The ZyAIR 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 ZyAIR and log in. Because TFTP does
not have any security checks, the ZyAIR 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.
