Usage
Information
You can configure multiple time-serving hosts (up to 250). 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.
