I found the error, Nexus can't sync with 9500, I changed it to a windows server 2016 and it works

Hi,

 

   Depending on the initial time difference, it may take more than instant synchronisation. Post the output of "show ntp status" and "show ntp associations detail" from IOS and "show ntp peer-status" from Nexus.

 

Regards,

Cristian Matei.

 - Did you enable NTP on the 5k with "feature ntp" ?
