Hello Team, Need some expertise level advise, I build ISE deployment with 2 nodes running on 3.2 version patch 6, both nodes are on VM RHEL 8 Operating system.
Now problem which i am facing, both nodes are not getting synch with NTP servers,
There is no firewall and NTP server is reachable from ISE, able to resolve the NTP hostname and IP from ISE CLI.
When i checked ISE packet capture i am seeing response from NTP server, for testing i added Core switch as NTP to check is there any problem wit ISE build but core switch got synch as NTP.
I opened a case with cisco and they responded saying....
I have analyzed the logs and found an exception related to the ntp server “Exception while performing getNTPConfig” .
I checked with the development team regarding the same and they mentioned that usually the error arises when there’s some invalid or unknown character is being received from the NTP server.
Current NTP which i am using and failing, but same NTP is working with other Cisco Products.
