Usage Information
You can congure 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 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 congured.
Related Commands show ntp associations — displays the NTP servers congured and their status.

Specify an interface’s IP address to be included in the NTP packets.
