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.
