Local or Global Broadcasts
Choose whether broadcasts will be local or global from the 'BROADCAST TYPE' radio buttons. The setting
changes between using the global broadcast address or a local broadcast address. The global broadcast
address is 255.255.255.255, while the local broadcast address depends on the network settings. For example,
if the port's IP address is 192.168.1.1 and the netmask is 255.255.255.0, then the local broadcast address will
be 192.168.1.255.
By default, the broadcast type is set to 'GLOBAL'.
4.
Enter Broadcast Interval
Enter the broadcast interval into the 'BROADCAST POLLING INTERVAL' timeboxes. This setting determines
how frequently the port will send broadcast NTP messages into the network. The supported interval range is
0-24 hours, the default setting is 2 seconds.
5.
Enter Multicast IP Address
Enter the IP Address for port to send multicasts NTP messages to. If the entered address is within
the reserved multicast address range (224.0.0.0–239.255.255.255), the message will also use a multicast
destination MAC address, otherwise it will use the broadcast MAC address.
6.
