Cisco ISE NTP Time Sync Frequency

[shawn.pattison]

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?

i can't remember now, on top of my head as I remember 1024 S (polling server)

Hi @shawn.pattison ,

 try the following command to check NTP info:

ise/admin# show ntp 
Configured NTP Servers: 
<NTP NAME>

Reference ID : 0AFC600C (<REFERENCE IP ADDR>)
Stratum : 4
Ref time (UTC) : Sun May 01 05:27:49 2022

M indicates the mode of the source.

S indicates the state of the sources.

Hope this helps !!!
