SNTP
The Network Time Protocol (NTP) is a protocol for synchronizing the clocks of computer systems
over packet-switched, variable-latency data networks. A less complex implementation of NTP,
using the same protocol but without requiring the storage of state over extended periods of time
is known as the Simple Network Time Protocol (SNTP). NTP provides Coordinated Universal Time
(UTC). No information about time zones or daylight saving time is transmitted; this information is
outside its scope and must be obtained separately.
UDP Port: 123.
Daylight saving is a period from late spring to early fall when many countries set their clocks ahead
of normal local time by one hour to give more daytime light in the evening.
Note:
1.
The SNTP server always replies the UTC current time.
2.
When the Switch receives the SNTP reply time, the Switch will adjust the time with the time
zone configuration and then configure the time to the Switch.
3.
If the time server’s IP address is not configured, the Switch will not send any SNTP request
packets.
4.
If no SNTP reply packets, the Switch will retry every 10 seconds forever.
