GS716Tv3, GS724Tv4, and GS748Tv5 Smart Switches  To configure the time by using SNTP: 1. Select System > Management > Time > Time Configuration. 2. Next to Clock Source, select the SNTP radio button. The screen refreshes, and additional fields appear. 3. Next to Client Mode 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. Click the Apply button. 5. If the SNTP client mode is Unicast, use the SNTP Server Configuration screen to add the IP address or DNS name of one or more SNTP servers for the switch to poll. For more information, see SNTP Server Configuration on page 43. The SNTP Global Status table on the Time Configuration screen displays information about the system's SNTP client. The following table describes the SNTP Global Status fields. Table 6. Time Configuration status fields Field Version Supported Mode Last Update Time Last Attempt Time Description Specifies the SNTP version the client supports.
