The following sections provide information on NTPv4.
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 must configure a Segmented Management Instance on applicable switches before you use NTPv4.
