Override Default Application Values

You can override default application values using the commands described in this section.

  1. View existing values.

    ~(keystone_admin)]$ system helm-override-show ptp-notification
ptp-notification notification

  2. Create a yaml file and update the fields that require Helm overrides.

    cat ~/override.yaml
ptptracking:
 device:
   holdover_seconds: 25
   poll_freq_seconds: 2

  3. Apply the values.

    Application values can be added by the user and applied, using the following commands.

    Note

    The application could be in the "uploaded" or "applied" state.

    ~(keystone_admin)]$ system helm-override-update ptp-notification ptp-notification notification -–values <<override.yaml>>
    ~(keystone_admin)]$ system application-apply ptp-notification

    where the values are:

    simulated

    value must be 'false' for a normal operation (used only for troubleshooting).

    holdover_seconds

    value is the holdover time provided by the specification. The default is 15 seconds.

    poll_freq_seconds

    is the frequency that the tracking function monitors the ptp4l to derive the sync state. The default is 2 seconds.
