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

Run system-view
The system view is displayed.
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.
Run clock alarm-threshold frequency-offset frequency-offset-value
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 frequency offset is 9200ppb.
