You can specify both interfaces using the [<ifname>] syntax. I believe all configuration options can be supported in each per-interface domain so you can set the configuration options you want for each interface separately, rather than putting them in [global]?

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.

You can run: - one ptp4l instance as a Boundary Clock with 1588 on the slave port and gPTP on the master ports (using a configuration file) - one phc2sys in "automatic" (-a) mode with --boundary_clock_jbod That will make the gPTP clients synchronize to the 1588 IPv4 master.
