It isn't working, obviously.

Forget linuxptp for the moment.  Use wirehark/tcpdump to see what
happens when you connect two sensors.

As you already know, there can be at most ONE peer in a P2P network.
If the switch allows two peers, then it is broken.

Unfortunately not.  I tried a Cisco switch that implemented E2E
correctly, but it had no P2P support.  I've seen a Lab-X switch that
did 802.1-AS (mostly) correctly.  I've never got my hands on a
commercial switch that implements P2P.

Also, there really aren't many choices on the market.  Sad.

Thanks,
Richard
