Cisco ISE NTP Time Sync Frequency

This might be something "everyone" knows but...

 

How often does Cisco Identity Services Engine sync it's time?

Is there an easy way to check this or can it be modified?

Hi @shawn.pattison ,

 try the following command to check NTP info:

ise/admin# show ntp 
Configured NTP Servers:

Stratum : 4
Ref time (UTC) : Sun May 01 05:27:49 2022
System time : 0.000000019 seconds slow of NTP time

MS Name/IP address Stratum Poll Reach LastRx Last sample
===============================================================================
^* <IP ADDR> 3 10 377 877 +80us[ +265us] +/- 43ms
M indicates the mode of the source.

Hope this helps !!!
