Not sure if these actually have anything to do with each other - but with my limited insight, it seems like they do. Some help please.
In the man page it says: > With the *-a* option, the clocks to synchronize are fetched from the running *ptp4l* daemon and the direction of synchronization automatically follows changes of the PTP port states. Is this talking about multiple PTP ports (clocks)? Is it saying that phc2sys will follow the roles decided by the PTP protocol, and set the PHC on ports that happen to be masters from a port that is a slave? All I can think is that this applies when the node is a boundary clock. Can someone comment? How does this play with the scenario where the node is the grandmaster? What is the direction of time synchronization in that case?
