Usage Information You can congure 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 congure, as many polls to the NTP hosts can impact network
performance.
