SNTP

SNTP (Simple Network Timing Protocol) is a protocol used to synchronize the system time to

the public SNTP servers. When the SNTP feature is enabled, your DSL600EW 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 DSL600EW 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 DSL600EW 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 DSL600EW.
