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 is selected, use the show ntp associations command.
Because many polls to NTP hosts can affect network performance, Dell Networking
recommends limiting the number of hosts configured.
By default, the system performs a time synchronization if the time difference from the
time source is greater than one second.
