How to disable tftp on cisco switch?

Hey there! Disabling TFTP on Cisco switches is actually pretty straightforward. TFTP (Trivial File Transfer Protocol) can be a security risk if you're not using it, so it's good practice to disable it. Here's how:

1. First, access your switch via console cable or SSH and enter global configuration mode: enable configure terminal
2. To disable the TFTP server completely, use: no tftp-server enable

3. If you want to be extra thorough, you can also block TFTP traffic (port 69) on your interfaces using access control lists.

4. Don't forget to save your configuration with write memory or copy running-config startup-config

Hope this helps! I've been managing Cisco networks for about 8 years now and always recommend disabling unused services as part of basic security hardening.

As a network security guy, I'd definitely recommend disabling TFTP unless you specifically need it. The protocol transmits everything in clear text - no encryption at all! Here's another method:

You can also restrict TFTP through the Cisco IOS File System by using: no ip tftp source-interface

And make sure to check if there are any specific TFTP configurations in your running config with show running-config | include tftp - remove any lines you find related to TFTP if you don't need them.

Just my two cents - better safe than sorry when it comes to network services!
