CLI: Set the Named SNTP Server
NETGEAR provides SNTP servers accessible by NETGEAR devices. Because NETGEAR
might change IP addresses assigned to its time servers, it is best to access an SNTP server
by DNS name instead of using a hard-coded IP address. The public time servers available
are time-a, time-b, and time-c.
Enable a DNS name server and access a time server with the following commands:
(Netgear switch) (config)#ip domain-lookup
(Netgear switch) (config)#ip name-server 192.168.1.1
(Netgear switch) (config)#sntp server time-a.netgear.com
where 192.168.1.1 is the public network gateway IP address for your device.
This method of setting DNS name look-up can be used for any other applications that require
a public IP address, for example, a RADIUS server.
