Usage
Information
You can configure multiple time serving hosts (up to 250). From these time serving hosts, the
FTOS will choose one NTP host with which to synchronize. Use the show ntp associations to
determine which server was selected.
Since a large number of polls to NTP hosts can impact network performance, Dell Force10
recommends that you limit the number of hosts configured.
