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.
