Usage Information

You can configure multiple time-serving hosts (up to 250). From these time-serving hosts, the system chooses one NTP host with which to synchronize. To determine which server was selected, use the show ntp associations command.

Because many polls to NTP hosts can impact network performance, Dell Networking OS recommends limiting the number of hosts configured.

Related Commands show ntp associations — displays the NTP servers configured and their status.
