Cisco ISE NTP Sync

[Flavio Miranda]

 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

  Don´t mind about it. After perform "no ntp server" and "ntp server" again, everything is ok know.

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
