Usage
Information
You can configure multiple time-serving hosts. From these time-serving hosts, the system chooses one
NTP host to synchronize with. To determine which server to select, use the show ntp associations
command. Dell EMC recommends limiting the number of hosts you configure, as many polls to the NTP
hosts can impact network performance.
