switch:
1. Configure the SNTP server IP address.
The IP address can be either from the public

following example configures the SNTP server IP address to 208.14.208.19.
(Netgear Switch) (Config)#sntp server 208.14.208.19

broadcast mode or unicast mode. If the NTP server is not your own, you must use unicast
mode.
(Netgear Switch) (Config)#sntp client mode unicast
3. Once SNTP client mode is enabled, the client waits for the polling interval to send the query
