Note that the telnet connection must be active and the SMT in CI mode before and during the
TFTP transfer. For details on TFTP commands (see following example), please consult the

23.2.4 Example: TFTP Command
The following is an example TFTP command:
TFTP [-i] host get rom-0 config.rom
where “i” specifies binary image transfer mode (use this mode when transferring binary files),
“host” is the ZyAIR IP address, “get” transfers the file source on the ZyAIR (rom-0 name of
the configuration file on the ZyAIR) to the file destination on the computer and renames it
config.rom.
“host” is the ZyAIR IP address, “get” transfers the file source on the ZyAIR (rom-0 name of
the configuration file on the ZyAIR) to the file destination on the computer and renames it
config.rom.
