Configuring Frequency Offset Check

Configuring Frequency Offset Check

Context

If the frequency offset value of a clock source is out of scope, the clock source is considered invalid and does not participate in clock source selection.

You can set the valid range of frequency offset to affect the result of clock source selection.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run clock freq-deviation-detect enable

    Frequency offset check is enabled to affect clock source selection.

    By default, frequency offset check is not enabled for clock signals.

  3. Run clock freq-deviation-detect-range left-range right-range

    The valid range of the frequency offset is set. If the frequency offset of a clock source is out of the specified range, the frequency offset is too high.

    By default, the maximum left frequency offset is -9.2 ppm, and the maximum right frequency offset is 9.2 ppm.
