Hi Linux PTP Users, We have pmc tool to query the ptp4l master offset. But is there a similar tool to check phc2sys offset?
I think we can use phc_ctl cmd using "cmp" cmd to get the offset between CLOCK_REALTIME & PHC. But I am looking for a tool like pmc which is capable of querying all devices in the network by setting the "-b" to non zero to go beyond the boundary clock. Please help. Another question, My ptp4l config uses the link local mac address (ptp_dst_mac 01:80:C2:00:00:0E) as I am using AUTOMOTIVE (slave-only) profile. The management msg generated using pmc cmd from ptp4l with -b option set to non-zero value is going out of the device, but it is getting discarded/consumed by the switch that's operating as Time Aware Switch. I am thinking if this could be due to the link local MAC addr I use. Is there a way (config ptp4l) to use the forwardable MAC addr (01-1B-19-00-00-00) just for the PTP Management messages? Thanks, Nemo
