4.4.1 ADVANCED - SNTP
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.
Place a check at Enable SNTP to enable the SNTP functionality.
When the SNTP feature is enabled, your ARM-104_v3 ADSL2/2+ Router 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.
Enable SNTP: Place a check to enable SNTP feature.
Primary SNTP Server: The IP address or the host name of the primary SNTP server.
Secondary SNTP Server: The IP address or the host name of the secondary SNTP server.
Tertiary SNTP Server: The IP address or the host name of the tertiary SNTP server.
Timeout: A time limit for an operation. If the ARM-104_v3 ADSL2/2+ Router failed to connect to a
SNTP server within the “Timeout” period, it will retry the connection.
Polling Interval: The length of time (In Minutes) the ARM-104_v3 ADSL2/2+ Router retrieves the
time from the SNTP Server. Time between a successful connection with a SNTP server and a new
attempt to connect to an SNTP server.
Retry Count: Enter the Retry Count to access the SNTP Server. The number of times the
ARM-104_v3 ADSL2/2+ Router will try to connect to an SNTP server before it try to connect to the
next server in line.
Time Zone: This specifies the time zone ( Geographical location ).
Day Light: Place a check at the Day Light to activate Daylight Savings Time.
