3.7.2 SNTP
Simple network timing protocol (SNTP) is a protocol used to synchronize the system time to
the public SNTP servers. It uses the UDP protocol on port 123 to communicate between
clients and servers. The figure below shows the default SNTP page.
When the SNTP feature is enabled, your SOHOSpeed starts querying for the time clock
information from the primary SNTP server. If it fails to get a valid response within the Timeout
period, it makes additional attempts based on the number specified in the Retry Count field
before moving to the Secondary SNTP server.
If it fails to get a valid response from Secondary STNP server within the specified retry count,
it starts querying the Tertiary SNTP server. If it fails to get a valid response from all the
servers, then the program stops. Once a valid response is received from one of the servers,
the program goes to sleep for number of minutes specified in the Polling Interval field before
starting the whole process again.
