SNTP Client and Clock Configuration
In the System Management section of the Configuration Menu, click on the SNTP client hyperlink. In this win-
dow, you may
configure the unit to get its time from a Simple Network Time Protocol (SNTP) server. If configured,
when the unit boots up, it will obtain its time from an SNTP server. In addition, during operation the unit will periodi-
cally resynchronize its time to the SNTP server to prevent its clock from drifting.
Configuring the SNTP Client Mode Parameters
Figure 26. SNTP Client Mode Configuration
Enable/disable the following parameters to configure SNTP client mode:
• Unicast Mode: In unicast mode, the unit periodically requests the time from the configured SNTP server.
In this mode, the unit always initiates communication with the server.
• Anycast Mode: In anycast mode, the unit sends a sync request to the local subnet broadcast address. It then
begins to operate in unicast mode with the first server to respond.
• Broadcast Mode: In broadcast mode, the unit listens for the time to be sent from a multicast NTP server.
In this mode, the unit only listens, but never replies to the server.
Click Set Mode to save your settings.
• Configured IP Address of SNTP Server:
- In unicast mode, this should be the IP address of an SNTP server reachable by the unit.
- In anycast mode, this should be the local subnet broadcast address.
- In broadcast mode, this field does not apply and may be set to 0.0.0.0.
