Cisco ISE NTP Sync

Hi folks,

Wondering if anybody knows the reason why a Cisco ISE is not in sync with NTP server. I am able to ping servers from ISE and the Wireless Controller is successfully synchronized.

Is there something more besides setup "ntp server" and timezone ?

synchronised to local net at stratum 11
time correct to within 11 ms
polling server every 1024 s

remote refid st t when poll reach delay offset jitter

Hi Flavio,

It happens with ISE and even ACS , they dont sync up properly or looses the synchorinization, You can either do no ntp server and ntp server again or you can restart the NTP service. even that helps at times

Cheers!!
