Note
DEMO FEATURE - NTPv4 Master Mode and Restrict is a demonstration feature on some products. Demonstration features are provided for testing purposes. Demonstration features are for lab use only and are not for use in a production environment. For more information, see VOSS Feature Support Matrix.
The following sections provide information on NTPv3 and NTPv4. If your platform supports both versions, the default is NTPv3.
Important
For NTPv4:
The switch can operate as both NTPv4 client and NTPv4 server.
The server selection algorithm can deem a server to be unfit to sync even though there is connectivity.
It can take several iterations (intervals) for the server to sync.
You need to configure a Segmented Management Instance on applicable switches before you use NTPv4.
