Now issue have been resolved by using the command;

 

"ip tftp blocksize 512"

 

I dont undersatnd why cisco says that "By default, the Catalyst 3850 uses a TFTP block size value of 512"

 

Thank all of you.

Hello,

 

what do you use as TFTP server ? Make sure you have specified the correct folder on your TFTP server. Right now you arevtrying to save the file to the root of your TFTP server...

Check if you mark correct folder and your tftp already configured to read and write.

The original post tells this

I can ping tftp server and vice versa from laptop

Can the original poster clarify whether the device is able to ping the tftp server, specifying that the source address for the ping is the address configured as tftp source address?

 

Also can the original poster tell us whether after making an attempt to tftp the file there are any messages on the tftp server showing that it received an attempt to copy the config file?

 

I have had the experience with some implementations of tftp server that the file name must already exist in the directory that the tftp server will use (sometimes is the root directory as suggested in a previous response and sometimes is a directory specified in the tftp setup). It might be worth a try to create the file in the appropriate directory and see if that makes any difference.

 

If there is not progress toward a solution it might provide helpful information to run debug for tftp, attempt the tftp copy, and post the debug output.

So the process wrote something and then stopped.  

I've seen this before and the issue is the TFTP server. 

Can you try getting another machine to be the TFTP server? 

1. I can ping from laptop to switch

2. I can ping from switch to laptop.

3. Used two other workstation/laptop, still the issue is same.

4. i can see the request coming to TFTP server .

 

Thanks in advance

Hello,

 

the destination filename (Destination filename [DC1xcik1-confg]) does not match the file name in your screenshot, why is that ?

What is the hostname of your switch (doesn't show in your running config) ?

sorry ..

i just change the file name due to security issues..... FYI...it matches.

 

Thanks

Hello,

 

not sure if this has been answered before, but what do you use as TFTP server ? And what OS (e.g. Wndows 10) is the TFTP server running on ?

I am using 3CDaemon as TFTP server and its running on win10 & win 7(tried both)
