Important:
Redundant NTP Multicast time server:
If in the same network two NTP servers should send NTP with the same
Multicast IP address (redundancy), then the first time server has to be
configured with a small
pollinterval
(e.g. 2  4 sec.) and the second time
server with a large pollinterval (min. 100 x larger, e.g. 9  512 seconds).
As long as the first time server is sending NTP Multicast packets, the
packets from second time server are ignored. This configuration is
needed, to reach a defined situation for the end devices (the DTS
480x.masterclock with the more frequently NTP send rate gets higher
priority for time reception).
