Netgear M4300-28G (GSM4328S) - Stackable Managed Switch with 24x1G and 4x10G including 2x10GBASE-T and 2xSFP+ Layer 3 管理者ガイド

The example is shown as CLI commands and as a web interface procedure.

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:

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.
