Managing NTP Servers

RUGGEDCOM ROX II can periodically refer to a remote NTP server to correct any accumulated drift in the
onboard clock. RUGGEDCOM ROX II can also serve time via SNTP (Simple Network Time Protocol) to hosts
that request it.
NTP servers can be added with or without authentication keys. To associate an authentication key with an NTP
server, first define a server key. For information about adding server keys, refer to
Server Key".
The following sections describe how to configure and manage NTP servers:
