Learn how to configure NTP services to ensure accurate time synchronization across network devices, which helps improve security, data integrity, and overall network performance.

Configuring an NTP server ensures accurate time synchronization across network devices, enhancing security, data integrity, application performance, compliance, and troubleshooting efficiency.

To configure the NTP server, follow these steps:

Procedure

  1. Open the terminal on Cisco IoT FND or the TPS server.

  2. Run the following command to edit the chrony.conf file:

    Example:

    nano /etc/chrony.conf
    This command opens the file in the nano text editor, displaying the current configuration details.

  3. Add the NTP server IP address:

    Example:

    server 209.165.200.225

    Replace 209.165.200.225 with the actual IP address of your desired NTP server.

  4. Save and exit.

  5. Restart the chrony service to apply the changes using the following command:

    Example:

    systemctl restart chronyd

  6. Verify the configured NTP server details using the following commend:

    Example:

    chronyc sources
    MS Name/IP address         Stratum Poll Reach LastRx Last sample
