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 savings 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.
Notes:
• The SNTP server always replies the UTC current time.
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.
If the time server's IP address is not configured, the Switch will not send any SNTP
•
request packets.
If no SNTP reply packets, the Switch will retry every 10 seconds forever.
•
If the Switch has received SNTP reply, the Switch will re-get the time from NTP server
•
every 24 hours.
If the time zone and time NTP server have been changed, the Switch will repeat the
•
query process.
No default SNTP server.
