Click the drop-down menu to select the SNTP client mode of operation.
The options are:
 Disable - SNTP is not operational. No SNTP requests are sent from the client
nor are any received SNTP messages 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.
 Broadcast - 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.
Enter the local UDP port (between 1 to 65535). The default is 0. When Port is 0, the
actual client port value is assigned by the operation system.
Enter the number of seconds (between 6 to 10) between unicast poll requests
expressed as a power of two when configured in unicast mode. The default is 6.
Enter the number of seconds (between 6 to 10) between broadcast poll requests
expressed as a power of two when configured in unicast mode. The default is 6.
Enter the number of seconds (between 1 to 30) to wait for a SNTP response when
configured in unicast mode. The default is 5.
