Disabling TFTP

I am trying to disable TFTP on my router but have had no luck. I have no tftp-server commands in the running config but I still seem to be able to connect to the router with a TFTP client. Is there anyway to stop the router from accepting tftp connections?

Ingress ACL or CoPP?

Hello

Following on from Vasilli comments, below are two examples for denying tftp to your router via CoPP and ACL

Router ip = 1.1.1.1/24

CoPP

access-list 100 permit tcp any host 1.1.1.1 eq telnet

class-map match-all notftp_cm
match access-group 100

policy-map notftp_pm
class notftp_cm
drop
class class-default

control-plane host
service-policy input notftp_pm


ACL

access-list 101 deny   tcp any host 1.1.1.1 eq telnet
access-list 101 permit ip any any

int x/x
ip access-group 101 in
