Netgear GS418TPP User Manual - Page 49

ProSAFE 8-Port or 16-Port Gigabit Smart Managed Switch Model GS418TPP, GS510TLP, and GS510TPP 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 provides a single-subnet scope while a multicast address provides an Internet-wide scope. The default value is Unicast. 7. In the Port field, specify the local UDP port that the SNTP client receives server packets on. The allowed range is 1025 to 65535 and the value 123. The default value is 123. When the default value is configured, the actual client port value used in SNTP packets is assigned by the operating system. 8. In the Unicast Poll Interval field, specify the number of seconds between unicast poll requests expressed as a power of 2. The allowed range is 6 to 10. The default value is 6. 9. In the Broadcast Poll Interval field, specify the number of seconds between broadcast poll requests expressed as a power of 2. Broadcasts received prior to the expiry of this interval are discarded. The allowed range is 6 to 10. The default value is 6. 10. In the Unicast Poll Timeout field, specify the number of seconds to wait for an SNTP response to a unicast poll request. The allowed range is 1 to 30. The default value is 5. 11. In the Unicast Poll Retry field, specify the number of times to retry a unicast poll request to an SNTP server after the first time-out before the switch attempts to use the next configured server. The allowed range is 0 to 10. The default value is 1. 12. In the Time Zone Name field, specify a time zone. You can also specify the number of hours and number of minutes that the time zone is different from the Coordinated Universal Time (UTC). The time zone can affect the display of the current system time. The default value is UTC. Note: When using SNTP/NTP time servers to update the switch's clock, the time data received from the server is based on the UTC, which is the same as Greenwich Mean Time (GMT). This might not be the time zone in which the switch is located. 13. In the Offset Hours field, specify the number of hours that the time zone is different from UTC. The allowed range is -12 to 13. The default value is 0. 14. In the Offset Minutes field, specify the number of minutes that the time zone is different from UTC. The allowed range is 0 to 59. The default value is 0.
