Explanation:
Broadcast means that data packets are sent from one point (here: OTMC 100) to all other subscribers
of a computer network. Broadcast is not supported by IPv6.
Multicast means that data packets are sent to a specific subset of subscribers only. This subset of
subscribers is specified by an address range, the multicast address. Multicasting therefore allows
much more efficient distribution of information.
IPv4 Broadcast Select the Enabled check box to enable the sending of IPv4 broadcast messages
containing NTP time information.
If enabled, enter the broadcast IP address in dot-decimal notation
(e.g.: 192.168.0.255).
Minpoll specifies the interval for sending the broadcast messages as a power of 2
(i.e., in 2
Possible values for Minpoll: 4 to 17 resulting in a broadcast interval between 16
and 131072 seconds.
IPv4 Multicast Select the Enabled check box to enable the sending of IPv4 multicast messages
containing NTP time information.
If enabled, enter the IPv4 multicast address in dot-decimal notation
(e.g.: 224.0.1.1).
Minpoll specifies the interval for sending the multicast messages as a power of 2
(i.e., in 2
Possible values for Minpoll: 4 to 17 resulting in a broadcast interval between 16
and 131072 seconds.
IPv6 Multicast Select the Enabled check box to enable the sending of IPv6 multicast messages
containing NTP time information.
If enabled, enter the IPv6 multicast address in hexadecimal notation
(e.g.: ff05::101).
Minpoll specifies the interval for sending the multicast messages as a power of 2
(i.e., in 2
Possible values for Minpoll: 4 to 17 resulting in a broadcast interval between 16
and 131072 seconds.
See the "ntp.conf man page" for a more detailed description of the NTP parameters (see
Linux command "man ntp.conf").
