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 recommends limiting the number of hosts configured.
