GS752TXS and GS728TXS Smart Switches 3. Next to the Client Mode field, select Unicast or Broadcast: • 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. 4. Optionally, configure the following settings to non default values: • Port. The local UDP port to listen for responses/broadcasts. • Unicast Poll Interval. The interval, in seconds, between unicast poll requests expressed as a power of two when configured in unicast mode. • Broadcast Poll Interval. The interval, in seconds, between broadcast poll requests expressed as a power of two when configured in broadcast mode. Broadcasts received prior to the expiry of this interval are discarded. • Unicast Poll Timeout. The timeout value, in seconds, to wait for an SNTP response when configured in unicast mode. • Unicast Poll Retry. The number of times to retry a request to an SNTP server after the first time-out before attempting to use the next configured server when configured in unicast mode. 39
