3. Next to Client Mode, select the mode of operation of the SNTP client:
• Disa
ble. SNTP is not operational. No SNTP requests are sent from the client nor will
any received SNTP messages be processed.
• Unicast.
SNTP operates in a point-to-point fashion. A unicast client sends a request
to a designated server at its unicast address and expects a reply from which it can
determine the time and, optionally the round-trip delay and local clock offset relative
to the server.
• Broa
dcast. SNTP operates in the same manner as multicast mode but uses a local
broadcast address, instead of a multicast address. The broadcast address has a
single subnet scope while a multicast address has Internet wide scope.
The default value is Disab
le.
