Does Cisco NTP support NTS? RFC 8915

[eviii]

I couldn't find anything about this topic. Does Cisco support Network Time Security from RFC 8915?

https://datatracker.ietf.org/doc/html/rfc8915

I couldn't find anything how to connect my Cisco Router to the NTS-Key Server how to configure this chain of trust at all?

Hello @eviii,

at this point of time Cisco devices do not support NTS as defined in RFC 8915. That's simply why you did not find anything about it.

You can only use some older secure NTP authentication mechanisms (MD5, SHA1, AES-128 CMAC) that are supported on IOS-XE.

HTH!
