Hello,
I am assessing an existing Data Center NTP implementation, which uses the famous pool.ntp.org server pools on the Internet. I have learned that Cisco devices do DNS resolution only when the command ntp server <pool name> is entered. After the command is entered, I can see the real NTP servers IP address in the command show ntp associations.
The problem is that is one or more servers go offline or simply do not serve NTP anymore, the client NTP process does not react on this situation ! Non responding servers are flagged as .INIT. in the show ntp associations command .
In the following document https://docs.ntpsec.org/latest/discover.html , one can read that the is a pool command that should allow the client process to re-initiate a DNS resolution if required
How to achieve the same behavior with IOS or NX-OS ?
Thank you
