File is in the bootflash:

UKENESLCSW001# copy bootflash: tftp:
Enter source filename: sniff_capture
Enter vrf (If no input, current vrf 'default' is considered):
Enter hostname for the tftp server: 10.232.7.100

TFTP put operation failed:File not found

Can anyone explain this please

It looks like a TFTP server issue, you can check the link below to see if that helps:

Hi

Surely that would only apply if I was pulling the file from the TFTP server. I am copying from the Nexus Switch to the TFTP. The file is on the Nexus bootflash:

[Dawei]

I tested in my lab if we are missing -c option, copy file to tftp server will show as "TFTP put operation failed:File not found "

[russell.sage]

Where does this -c option need to go. I my TFTP server via a Windows management mapped drive. I presume, as I don't have access to the TFTP server it's a windows machine. Does this -c option need to be applied on the Nexus switch? I thought that was a client

[Dawei]

"File not found" is an error returned by the TFTP Server (Your windows), which is indeed confusing, but you can verify this with ethanalyzer. It's because you don't have permission to create files on TFTP server. On the Linux TFTP server we need the -c option to allow create a new file, you may need to find a similar option on windows.

Hi
This is Nexus specific. No issues with Catalyst switches or Cisco 4000 and ASR series routers.
