Command Mode CONFIGURATION
Usage Information You can configure multiple time-serving hosts. From these time-serving hosts, the system chooses one NTP host
to synchronize with. To determine which server to select, use the show ntp associations command. Dell
EMC recommends limiting the number of hosts you configure, as many polls to the NTP hosts can impact
network performance.
Supported on the MX9116n and MX5108n switches in Full Switch mode starting in release 10.4.0E(R3S). Also
supported in SmartFabric mode starting in release 10.5.0.1
