Usage Information
You can congure multiple time-serving hosts (up to 250). From these time-serving hosts, the system 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 OS recommends limiting the
number of hosts congured.
Related Commands show ntp associations — displays the NTP servers congured and their status.
ntp source
Specify an interface’s IP address to be included in the NTP packets.
