SNTP
SNTP (Simple Network Timing Protocol) 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. When the SNTP feature is
enabled, your DSL600EU will start querying for the time clock information
from the primary SNTP server. If it fails to get a valid response within the
“timeout” period, it will try for “retry” number of times, before moving to the
Secondary SNTP server. If it fails to get a valid response from Secondary
STNP server within valid retry times, it starts querying Tertiary SNTP server.
If it fails to get a valid response from all the servers, then the program
stops. When a valid response is received from one of the server, the program
sleeps for “Polling_interval” amount of minutes, before starting the whole
process again.
Use the following procedures to enable SNTP.
1.
Check Enable SNTP.
2.
Primary SNTP Server - The IP address or the host name of the primary
SNTP server.
3.
Secondary SNTP Server - The IP address or the host name of the
secondary SNTP server.
4.
Tertiary SNTP Server - The IP address or the host name of the tertiary
SNTP server.
5.
Timeout - If the DSL600EU failed to connect to a SNTP server within the
‘Timeout’ period, it will retry the connection.
6.
Polling Interval - Time between a successful connection with a SNTP
server and a new attempt to connect to an SNTP server.
7.
Retry Count - The number of times the DSL600EU will try to connect to
an SNTP server before it try to connect to the next server in line.
8.
Time Zone - The time zone of the DSL600EU.
9.
Day Light - Check/uncheck this option to enable/disable day light
saving. See Fig 1-23.
