Setting the System Time

Scenarios

The edge device supports time synchronization from a unified time server to meet the video data time synchronization requirements in typical scenarios, such as smart transportation, smart parks, and smart retail.

Parameter Description

Setting the System Time

You can set the system time by manually adjusting the time or automatically synchronizing the time with the NTP server.

• Manually correct the time.
  1. Choose Management > Time > Set System Time.

  2. Click the time drop-down list box to set the date and time.
     

     • The time supported by the system ranges from 2015-01-01 00:00:00 to 2099-12-31 23:59:59.
     • Changing the time may cause the certificate and password to expire. If the certificate expires due to time change, log in to the background and restart the system.

     Parameter	Description
     Enable NTP	Enables or disables the NTP function of the edge device. If the NTP function is enabled, the time can be synchronized with the NTP server. Click or to enable or disable the NTP function, and then click Save. indicates that the NTP function is enabled. indicates that the NTP function is disabled.

  3. Configure the NTP server address as prompted. For details about the configuration items, see Table 3.

     Table 3 NTP server address parameters

     Parameter	Description
     Preferred NTP Server Address	IP address of the NTP server that is preferentially selected. Value: an IPv4 address
     Alternate NTP Server Address	IP address of the NTP server that is alternatively selected. Value: an IPv4 address

  4. Click Save.
     A dialog box is displayed in the upper part of the page, indicating that the settings are saved successfully. The device time is the NTP server time.

     If a terminal device is connected to the edge device, the terminal device can be configured to synchronize time with the NTP server based on the networking scenario.

     Prerequisites: The IP address of one NIC of the edge device can connect to the NTP server.

     • Atlas 200I A2 IP: a200I_ip1 (IP address for connecting to the NTP server)
     • IP address in the same network segment as the device: a200I_ip2
     • Device IP address: device_ip

     Configuration procedure:

     1. Configure the device IP address.
        • Scenario 1: The IP address of the device is in the same network segment as the IP address of the NTP server connected with the edge device.

          The route of the device is the same as that of the edge device by default. You only need to set the NTP server IP address in the NTP configuration.

        • Scenario 2: The device IP address and the IP address of the NTP server connected with the edge device are in different network segments, but are in the same network segment as the IP addresses of other NICs of the edge device.

          Configure the device route that is destined for the IP address in the same network segment of the edge device: route add -net 0.0.0.0 gw a200I_ip2

     2. Configure the reverse route on the NTP server: route add -host device_ip gw a200I_ip1
