Usage
Information
You can configure multiple time-serving hosts (up to 250). From these time-serving hosts, the operating
system chooses one NTP host with which to synchronize.
Because many polls to NTP hosts can impact network performance, Dell Networking recommends limiting
the number of hosts configured.
ntp authenticate
Enable authentication of NTP traffic between the switch and the NTP time serving hosts.
Syntax
ntp authenticate
To disable NTP authentication, use the no ntp authentication command.
Defaults Not enabled.
