change your file path, by deleting c:\temp\/ and just use /.

TFTP Path = /

Hope this helps.

Hi Krishan,

TFTP Path=/ :- It takes automatically.

I have tried both ways as mentioned below

Example:-

(Controller) # Transfer download path c:\temp\

and

2)

(Controller) # Transfer download path c:\temp

But the result is same nothing happens. Kinbdly let me know why is this happening.

Thanks in advance.

I would not use c:\temp just make sure that you point your tftp server to the folder where the file is:

(Controller) # Transfer download path /

also make sure that your tftp server supports files of a 30Meg, tftpd32 is a good tftp server.

Hi Kris,

Still i am facing the same problem.Now i have downloaded the tftpd32 and I tried connecting via the Service Port interface which has a different IP address. I conneced to the controller via the console cable to issue the commands but it still will not transfer. I can ping the tftp server from the Controller. I used the paths specified , ie , "." and "./" but stil the result is same.

Kindly let me know if there is any thing missing?

Thanks in advance.
