Use the following steps to configure an Ericsson Cradlepoint router to act as a Network Time Protocol (NTP) server for its LAN clients. See Ericsson Cradlepoint Routers That Can Act as NTP Servers for information about compatible routers.
Log into NetCloud Manager.
Select in the left-side navigation panel.
Select a router from the Routers page. Alternatively, to make configuration changes to a group, navigate to the Groups page and select a group.
Select and then .
Navigate to > > .
Under Network Time Protocol (NTP), select NTP Server/Client.
Under NTP Servers, select .
The NTP Server Editor dialog displays.
Enter the NTP server information the router will use for time synchronization. More than one NTP server can be added for redundancy purposes.
Server – Enter the IP or hostname of the server.
Port – Enter the port on which the server understands NTP requests. For normal servers, this option should not be changed (the default is 123, the standard NTP port).
Key ID – Client will attempt to authenticate packets if the key ID and key is present when communicating with the server. Valid key IDs are 1 through 4,294,967,295. The key may be no longer than 1,023 characters.
Key – The key ID and key must match between client and server, otherwise no relationship between them will be possible.
NTP version – Sets the NTP version number in packets sent to the server. This can be useful when the server runs an old NTP implementation that does not respond to newer versions. The default version number is 4.
Select .
Add other servers, if necessary.
