Description
This message allows the user to specify a priority for each line interface. When
configured to recover clock from the line interfaces, this priority is used to decide
which line interface to use as the clock source. The highest priority in-sync line
interface is used, with the board automatically moving through the list of clock sources
as line interfaces lose synchronization or are deemed stable again. If no interfaces are
in sync, the board remains in holdover mode, based on the last valid clock that was
recovered.
The confirmation message (if requested) indicates success with a status value of 0.
