Version Description
6.1.1.0 Introduced on the E-Series.
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.
