Configuration Tsunami MP.11 5012-SUR Installation and Management
Network Parameters
If SNTP feature is enabled, the device will attempt to retrieve the time of day from the configured time servers (primary or
secondary). If successful, the TMP device will periodically poll the timeserver it has communicated with to synchronize
the time of day information. If SNTP is disabled, or if it fails to communicate with the configured time servers, it will use
the system uptime to update the relevant time objects. If this feature is disabled, then you can manually configure the
date and time parameters. If you do not configure these objects manually, then they will be populated with the device’s
system uptime.
NOTES:The time servers can be configured using either the host name (Domain Name) or the IP address. If these
servers are configured with the host name, then the DNS client feature must be enabled and configured properly.
• If a time server is configured with a 0.0.0.0 IP address, then the SNTP client in the TMP device will not send a
time request to that server.
• When SNTP is enabled, it will take some time for the device to retrieve the time of day from the configured time
servers and update the relevant date and time parameters.
Primary and Secondary SNTP Servers
The SNTP client first attempts to retrieve the time of day from the configured primary server. If the device does not
receive a response from the primary server, then it tries the secondary server. If the device does not receive a response
from the secondary server, then it again attempts the primary server. The device retries a total of three times the primary
and secondary servers.
DNS Server requirement
When you configure the Domain Name of the SNTP server, the device resolves the SNTP server address with either
primary or secondary DNS server.
Synchronizing Time of Day
If the SNTP client is successful in retrieving the time of day information, then it resends time of day requests to the server
it is communicating with every ten minutes. This is a fixed value and is not configurable. This is done in order to
synchronize the time.
Configuring SNTP-DNS
Click Configure > Network > SNTP-DNS to enable the SNTP-DNS feature.
The following parameters are configurable.
1. DNS Client
• DNS Client Status: Enable DNS Client by selecting Enable from the DNS Client Status drop-down menu.
• DNS Primary Server IP Address: Represents the primary SNTP server IP address or host name.
• DNS Secondary Server IP Address: Represents the secondary SNTP server IP address or host name.
• DNS Client Default Domain Name: Represents the default domain name of the DNS Client.
2. SNTP
• Enable SNTP Status: Enable SNTP Status by selecting the Enable SNTP Status checkbox.
NOTE: The following fields are configurable only when SNTP Status is enabled.
• Address Format: Specifies whether the host name or IP address is used in configuring the primary and secondary
SNTP servers. By default, IP address is used in configuring the primary and secondary SNTP servers.
• Primary Time server: Represents the primary SNTP server IP address or host name.
• Secondary Time Server: Represents the secondary SNTP server IP address or host name.
• Time Zone:Select the appropriate time zone for your device.
