Appendix A
TFTP
Background
Software can be downloaded using the Trivial File Transfer Protocol (TFTP)
and ATI’s image file. ATI’s switches support the use of TFTP in ASCII mode
to both upload configuration parameters to a host and/or download
configuration parameters to a switch.
What this means is straightforward: you can save configuration data from
many switches to a single host. TFTP also allows you to change the
configuration parameters of all switches easily through the use of an editor
and a batch file. Switches can even be reset to the factory default
configuration, if needed. Finally, using defined keywords, any configured
parameter can be changed once the switch has a configured IP address.
To use TFTP, you will need the following:
❑
A TCP/IP stack and a copy of the TFTP utility on your workstation
❑
The download password
❑
The name of the file on the remote host
❑
The IP address of the remote host (the switch)
❑
The local filename (or image filename)
The included tables list the configuration fields and the required character
string which precedes the user-chosen configuration value. Every TFTP
configuration, received as either a “get” or a “put” to the device, must have
the string “ATI CONFIGURE’ as the very first line in the file. On a “put”,
this string informs the device what the receiving data is.
NOTE
Any file sent through TFTP in ASCII mode without the “ATI CONFIGURE’
string present at its very beginning, will be considered an illegal file transfer
and the session will be aborted.
