The NTP client protocol is incorporated with the operating system that is included with LSMS. If you choose to implement the LSMS as an NTP client, you must set up one or more NTP servers in your own network (or synchronize with some portion of the existing NTP subnet that runs on the Internet) and configure the LSMS to contact those NTP servers. For information about selecting NTP servers and configuring the LSMS as an NTP client and about displaying current settings for NTP, refer to the Configuration Guide.
If you prefer not to configure the LSMS as an NTP client, you can manually reset the LSMS time when it drifts out of synchronization with the NPAC time, as described in Manually Controlling the LSMS Time Without an External NTP Source.
