Usage
Information
You can configure multiple time-serving hosts . From these time-serving hosts, the Dell Networking OS
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.
