I have the following NTP servers configured on different switches
ntp server 192.168.1.1
ntp server 10.10.10.10 key 1
ntp server 126.96.36.199
ntp server 188.8.131.52 key 1
ntp server 184.108.40.206 key 30
The correct NTP servers are only 10.10.10.10 and 192.168.1.1. The problem is that as you see, the IP addresses of the NTP servers are very generic, meaning that in my large network, I may find any other NTP server.
Can you develop a code to run by Compliance Management to exclude any unneeded NTP servers ? It is required that the code catches any IP address and any key that is not matching the first two servers.
