Does Cisco support NTPv4?

[ak1871]

NTPv4 makes it possible to encrypt NTP traffic via symmetric key.

So does Cisco already support NTPv4?

Thanks for any feedback.

I refered to the command reference guide of 12.3 and it has only options for "ntp broadcast' command as versions 1 to 3. So I believe NTP4 is still not supported.
