I apologize for my ignorance but I'm not sure how to implement that all in a single configuration file. I currently have two very generic configuration files. The first is used on the primary interface as the 1588 slave:
*[global]* *slaveOnly 1* *time_stamping hardware* *step_threshold 1.0* *delay_mechanism Auto* *network_transport UDPv4* *[enp11s0]* The second configuration file is the default automotive-master.cfg profile: https://github.com/richardcochran/linuxptp/blob/master/configs/automotive-master.cfg I run the primary configuration file like this: ptp4l -f <path_to_file> For the other interfaces I run: *ptp4l -f /etc/automotive-master.cfg -i <interface_name>* I can add --boundary_clock_jbod to my automotive-master.cfg file and add the automotive interfaces and a boundary clock is properly formed between them. However, I don't know how to create a configuration file of dissimilar PTP instances on different interfaces. I will keep investigating and experimenting while I await a reply.
