Configure the system time synchronization

To configure or change the system time synchronization:

  1. Choose the management interface you want to use to access your device. Click a dropdown for instructions.

    1. Log in to Digi Remote Manager.

    1. Navigate to the device's dashboard.

    1. Log in to your device's Web UI.

    Log in to your device's Admin CLI via an SSH client, Telnet client, or terminal emulator.

  2. Configure the settings.

    1. Click to open the device's configuration menu.

      • In Digi Remote Manager, on the device dashboard, click Settings.

      • In the Web UI, click Device Configuration.

    2. Click System > Time.
    3. Modify the settings.

      CAUTION! If you enable the NTP service, either disable the server configured in system time or make sure to match the server(s) configured in service ntp server. If you do not do one of these options, then the System time synchronization may fail, which could result in the following error message: ntpdate[2901]: the NTP socket is in use, exiting.

      4. System time setting UI Configuration

      Timezone

       

      Choose the time zone closest to where the device is located.

      The default time zone is UTC.
      Resynchronization interval

      Type the frequency of the daily update.

      The default is 1d (one day).

      Set to O (zero) for no synchronization.
      Time sources

      1. Click to add a new time source.

        The time source is now enabled by default.

      2. In Type of time source, choose whether you want to use an NTP or Modem as the external source to which the device synchronizes.

        • If using an NTP, click to add the Server hostname.

          The default is time.devicecloud.com.

          Note If multiple NTP servers are added, time samples are obtained from each server. Selection algorithms are used to determine the most accurate time.

        • If using a modem, specify the Modem and Modem time offset.

          The default offset is Local.

    4. Click Apply to save the configuration and apply the change.

    1. At the CLI prompt, type config and then press Enter.

    2. Type system time to enter configuration mode for system time.

       > config system time
(config system time)>

    3. Add a new time source or modify the settings.

      CAUTION! If you enable the NTP service, either disable the server configured in system time or make sure to match the server(s) configured in service ntp server. If you do not do one of these options, then the System time synchronization may fail, which could result in the following error message: ntpdate[2901]: the NTP socket is in use, exiting.

      System time setting UI Configuration

      Timezone

       

      (Optional) Set the timezone for the location of your IX10 device. The default is UTC. 

      (config)> system time timezone value
(config)>

      Where value is the timezone using the format specified with the following command:

      (config)> system time timezone ?

Timezone: The timezone for the location of this device. This is used to adjust the time for log
messages. It also affects actions that occur at a specific time of day.
Format:
  Africa/Abidjan
  Africa/Accra
  Africa/Addis_Ababa
  ...

(config)>

      Resynchronization interval

      Type the frequency of the daily update.

      The default is 1d (one day). Set to O (zero) for no synchronization.

      (config) system time resync_interval value
(config) >

      Where value is {w|d|h|m|s}. For more information:

      (config)> system time resync_interval ?

Format: number {w|d|h|m|s}...
Optional: yes
Dafault value: 1 d
Current value: 1 d
(config)>
      Time sources

      Add a new time source, either an NTP server or a modem.

      Note The default NTP server is time.devicecloud.com.

      • If adding one or more NTP servers:

        add service ntp server 0 time.server.com

        Note If multiple NTP servers are added, time samples are obtained from each server. Selection algorithms are used to determine the most accurate time.

        Note This list is synchronized with the list of servers included with NTP server configuration, and changes made to one will be reflected in the other. See Configure the device as an NTP server for more information about NTP server configuration.

      • If adding a modem, specify the mode and time offset:

        The default offset is Local.

        (config system time source)> add end
(config system time source 1)>
(config system time source 1)> type modem
(config time source 1) > modem modem

      • To see the modem and its settings:

        (config system time source 1)> show
enable true
no label
modem modem
offset local
type modem
    4. Save the configuration and apply the change.
      (config)> save
Configuration saved.
>
    5. Type exit to exit the Admin CLI.

      Depending on your device configuration, you may be presented with an Access selection menu. Type quit to disconnect from the device.

Test the connection to the NTP servers

The following procedure tests the configured NTP servers for connectivity. This test does not affect the device's current local date and time.

To test the connection:

  1. Choose the management interface you want to use to access your device. Click a dropdown for instructions.

    1. Log in to Digi Remote Manager.

    1. Navigate to the device's dashboard.

    1. Log in to your device's Web UI.

    Log in to your device's Admin CLI via an SSH client, Telnet client, or terminal emulator.

  2. Configure the settings.

    1. At the CLI prompt, type config and then press Enter.

    2. Test the configured NTP servers for connectivity

      > system time test
Testing NTP server time.devicecloud.com on UDP port 123...

    3. Type exit to exit the Admin CLI.

      Depending on your device configuration, you may be presented with an Access selection menu. Type quit to disconnect from the device.

Manually synchronize with the NTP server

To perform an NTP query to the configured servers and set the local time to the first server that responds:

  1. Configure the settings.

    1. At the CLI prompt, type config and then press Enter.

    2. Select the device in Remote Manager and click Actions > Open Console, or log into the IX10 local command line as a user with full Admin access rights.

      Depending on your device configuration, you may be presented with an Access selection menu. Type admin to access the Admin CLI.

    3. Synchronize the device's local date and time: 
      > system time sync
24 Aug 22:03:55 ntpdate[2520]: step time server 52.2.40.158 offset -0.000487 sec
NTP sync to time.devicecloud.com successful
>
    4. Type exit to exit the Admin CLI.

      Depending on your device configuration, you may be presented with an Access selection menu. Type quit to disconnect from the device.
