Usage
Information
You can configure multiple time-serving hosts (up to 250). From these time-serving hosts, the operating
system chooses one NTP host with which to synchronize.
Because many polls to NTP hosts can impact network performance, Dell Networking recommends limiting
the number of hosts configured.
