Configure SNTP
The example is shown as CLI commands and as a Web interface procedure.
CLI: Configure SNTP
NETGEAR switches do not have a built-in real-time clock. However, it is possible to use 
SNTP to get the time from a public SNTP/NTP server over the Internet. You may need 
permission from those public time servers. The following steps configure SNTP on the 
switch:
1. 
Configure the SNTP server IP address. The IP address can be either from the public 
NTP server or your own. You can search the Internet to locate the public server. The 
servers available could be listed in domain-name format instead of address format. In 
that case, use the ping command on the PC to find the server’s IP address. The 
following example configures the SNTP server IP address to 208.14.208.19.
2. 
After configuring the IP address, enable SNTP client mode. The client mode can be either 
broadcast mode or unicast mode. If the NTP server is not your own, you must use unicast 
mode.
3. 
Once SNTP client mode is enabled, the client waits for the polling interval to send the query 
to the server. The default value is approximately 1 minute. After this period, issue the show 
(Netgear Switch) (Config)#sntp server 208.14.208.19
(Netgear Switch) (Config)#sntp client mode unicast
