According to the output in the post from @mkazam001 there is not an option to disable the tftp service on that platform running that version of code. Is there a reason you are concerned about service tftp on that platform? Perhaps there is another way to achieve what you need?

I'm trying to disable because of switch security recommendations, but I don't see the command. If default is disabled, i want to know the documentation to find it.

[Richard Burts]

Are the security recommendations specific to this platform and version of code? Or are the security recommendations more general about networking equipment?

security recommendations more general about networking equipment.

Thanks for the clarification. In this case I am confident that this function is not supported on that platform and that version of code. I do not have a Cisco document to support this. If it is really important to have a document supporting this then I suggest that you open a case with Cisco TAC.
