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.
(Netgear Switch) (Config)#sntp server 208.14.208.19
2. After configuring the IP address, enable SNTP client mode. The client mode may be either 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 enabled, the client will wait for the polling interval to send the query to the server. The default
value is approximately one minute. After this period, issue the show command to confirm the time has
been received. The time will be used in all logging messages.
(Netgear Switch) #show sntp server
