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 by status of zero.
