Hello,
I saw, by using a port scan, that the tftp upd port is open.
Is there any threat?
It is possible to turn it off?
Thank You!
PORT STATE SERVICE 69/udp open|filtered tftp Nmap done: 1 IP address (1 host up) scanned in 0.45 seconds

Hi :)
Sometimes these vulnerabilities are also present, so you should disable it if you don't need it.
e.g. https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20150722-tftp
Please see "Workarounds".

Thank for your reply,
I have no tftp-server lines in my configuration.
NR01#show running-config | i tftp NR01#show running-config | i ftp NR01#
Even so, the port seems to be open.
Any clues why and how can I turn the service off since I do not need it?
Regards.

Well, I also tried nmap with my c890(15.1(4)M1), but 69/udp is closed.
Can you post the result of the following command?
# show control-plane host open-ports
