• Disable - Stops synchronization via broadcast mode.
Anycast Mode:
• Enable - The SNTP client sends time synchronized broadcast packets to the network and
subsequently expects a reply from a valid timeserver. The client then uses the first reply it
receives to establish a link for future sync operations in unicast mode. This server will then be
added to the server association list. The client ignores any later replies from servers after the
first one is received.
