How do I disable TFTP services on a Cisco C2960S-24TS switch? The IOS version is 12.2 (55). This switch sits on the outside of our network and needs to be 'hardened' for security purposes. I ran the 'no tftp' command for Flash, null, nvram, system and tmpsys file load requests but it's still showing as available. (We are using an outside vendor to run pen tests on it and they are reporting this.) Should I have rebooted the switch after running this? Any help would be much appreciated.
