Hi, I'm trying to set up channel bonding with ptp4l. Few things are not clear to me:
1. I guess the only supported mode is active-backup !? 2. Which interface(s) do I specify to ptp4l? The bond or the slaves? If it is the slaves, do I run one or two instances of ptp4l? 3. Any other restrictions, e.g. ports must share the same PHC? And more in general: are there other recommended ways to achieve redundancy (using default profile, E2E, HW timestamping and UDP multicast). I used timemaster with 2x ptp4l --> phc2sys --> SHM --> chrony - this worked for me, but I didn't get to test performance yet. Could something similar be achieved just with phc2sys somehow switching between two ptp4l instances/ports? many thanks for your help! Christian Soenke
